 types of lugs

Electricians these days are making use of various Types of lugs on the electrical cables that provide a firm connection between the cable and the equipment. There are four types of cable lugs which are commonly used in electrical construction. Different types of cable lugs are also available based on their size. When a permanent connection is needed, then a cable lug or connector is used however a direct one is inconvenient or next to impossible to attain. Lugs comprise high-grade electrolytic (ETP Grade) and are available in a variety of diameters and mounting holes, with wire sizes that range from #8 AWG to 1000 MCM.

Types of cable lugs

Depending on the application and the industry, the usage of cable lugs differs. There are several alternatives for every installation framework. Types of lugs are categorized on the basis of their body structures, insulation and cross-sections.Copper lugs

Copper lugs are mostly used for power draw or grounding in large gauge applications. The wire can be mended or crimped to every copper lug. Subject to the specific type of lug used, one point of the copper lug takes the cable by welding, soldering or crimping. The other point of the copper lug is attached to a very end or connection point by a bolt, screw or spring clip.

Copper cable lugs provide simple installation and long-lasting authenticity. Pioneer copper lugs are made from high-grade copper material and tinned in order to protect them from corrosion. It is considered a brilliant option for any external application or in a marine environment.

Copper lugs are way better in several ways, however, copper lugs are a little more exorbitant compared to aluminium lugs. Flat-type lugs are largely used in the electrical industryAluminium lugs

Aluminium lugs are made from the solid aluminium rod using high conductivity (99.6 % pure) aluminium. The aluminium lugs are manufactured from solid and firm material and are apt for external usage due to the palm ends being sealed. The aluminium cable lugs are equipped with jointing compounds in the barrels and are sealed with a cap at the endpoint. Pioneer has a list of basic sizes but can produce aluminium lug types as per the needs.

Aluminium lugs are barrel entry chamfered at the end to allow for simple insertion into a barrel and are tinned with a middle layer of copper coating for corrosion protection.Mechanical lugs

The ideal approach for joining cable conductors is mechanical connection technology, which uses cutting-edge components like shear-off bolted connectors. At a preset torque, the bolt head is sheared off in this case. Certain alloys are used to make these mechanical connectors or shear bolt connectors. These connections consist of high-tensile aluminium alloy lug bodies and sleeves. The internal sides of the connectors are adapted and the sleeves are apt for underground use. These lugs are available in various palm hole sizes and are relevant both externally and internally. These products can be availed in low voltage, medium voltage and high voltage versions.Pin type lug

The connection part of pin-type lugs consists of a thin and elongated structure. It is found in the shape of a needle. It is designed to cut off conductors into contact blocks. It is used with respect to the termination of blocks and some electronic components. Pin type lugs are available in different sizes such as 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120.

Types of lugs and their application

Lugs types and size also matter in order to ensure the efficiency and effectiveness of an electrical appliance.

One of the primary functions of copper lugs is the connection of wires to electrical devices. Both power cable systems and electronic equipment can benefit from the usage of copper lugs.

Copper lugs work well in both power cable systems and electrical equipment. Insulated lugs consisting of pin terminals, blade terminals, hook terminals, fork terminals and ring terminals are utilized in the wire, automation, control panel and instrumentation industries.

Butt and parallel connectors are other types of lugs that connect and cut off two cables. Among the most commonly used butt and parallel connections are PVC insulated, butt type, heat shrinkable and close-end type.

In solar plants, bimetallic lugs are used to join copper busbars and aluminium conductors in a variety of electrical applications, including combiner boxes, switchgear, and control panels. Whereas ring type of lugs is used in blot & nuts plotted areas. We use this type of connector in MCB, MCCB, ACB, OCB, and the electrical panel areas.

Boot-type connectors are frequently used for control and instrument cables. U type of lugs is used in the relays, timer, contactor and MCB areas. Understanding the types of lugs and their application is essential to choosing the right kind of lug for the required appliance.

Different types of cable lugs and sizes of electrical lugs

Ring type cable lug sizes: 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120 (Diameter of the hole depends on bolt size such as 8 or 10)
Cable lug sizes of U type : 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120
Boot lace type cable lug sizes: 1, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 90, 120
Copper lug cable sizes range from: 1.5 sq mm to 1000 sq mm

Cable lugs sizes help to select the right kind of lug for a particular electrical appliance which helps in the efficient functioning of a particular system.

FAQs

What are cable lugs?

Cable lugs are connectors used to connect/cut off cables together constituting a significant part of an electrical system. Cable lugs are usually made up of one of two metals – copper or aluminium or their respective alloys.Why are cable lugs used?

Cable lugs help in the installation, restoration and maintenance of electrical gadgets and cables simple. They join two wires together or link more than two cables. They also connect load switches, fuse sockets and electrical equipment.Why are bimetallic cable lugs used?

Bimetallic Lugs are primarily handy where an aluminium cable has to be cut off by a copper bus bar or copper contact. The usage of bimetallic lugs assures a technically sound and lasting joint.What are cable lugs made of?

Cable lugs are usually made up of two metals – copper or aluminium or their respective alloys.How many types of lugs exist?

As per various installation processes and structural forms, lugs are divided into two types: bolt type and compression type.

Lugs form the most important part of an electrical system. Copper lugs are used for connecting/terminating wires and cable ends to electrical equipment. Its design allows it to easily secure and detach electrical joints permanently or for maintenance purposes. Since they connect devices seamlessly, they are essential for using electricity across different applications. Owing to its ubiquitous nature across devices, one must account for the quality of material used, correct type of lug, tools, and dies as they are crucial factors in determining the durability and reliability of the connection established.Classification Of Copper Lugs:

According to the structure, design, and types of connection established, the lugs can be distributed under two categories.Compression lugs-

The lugs are compressed along with the cable to establish a seamless connection. The joints between the wires and electrical equipment are crimped using relevant tools and dies which leads to lesser current loss.Mechanical lugs-

These lugs are designed to hold the bolts on one end and support the cable on the other. The bolts are then tightened for endpoint connection.

Cable Lug Design Specifics:

The two ends of the lugs are manufactured in a structure that supports cable and terminal connection on either end respectively. The cable is connected on one end using soldering, crimping, or welding. The use of any method depends on the connection to be established.

The other end is attached to the terminal point with a screw, bolt, or spring clip. The latter is selected on the basis of compatibility with the terminal type and method of connection.

Cable Lugs Installation Process- Things You Should Know

Step 1- Correct Identification

In accordance with four international standards, the cable lugs are available in different sizes and specifications. It follows:

• Indian Standards
• DIN Standards
• BS Standards
• AS/NZ Standards

Step 2- Preconditions

• Any personnel involved must follow appropriate safety precautions.
• The personnel must correctly identify the right type of lug for the required connection.
• The crimping device must be of the recommended dimensions to create the perfect compression.
• The insulation around the cable should be removed in accordance with the insertion depth of the connector and the wire strands should not be disturbed.
• The surface should be brushed to remove any oxides.
• Insert the cable strands into the barrel in its entirety and crimp it throughout.
• Lugs should be used as per the recommended size and structure.
• The cable insulation should not be stripped more than the recommended length to ensure an efficient and safe connection.
• The crimping dies should be used as per the lug shape and structure.
• The strands of the cable must be inserted into the barrel end of the lug. Once done, it should be made into a joint using crimping tools and die.
• The barrel of the lug must be tightened around the uninsulated cable strands to maximize connection efficiency.
• Every lug has a different crimping style and thus demands a different crimping tool. The proper crimping tool dies do not allow any loops for air space thus reducing resistance, increase in temperature, or fire risk.

Mechanical lugs form a core part of the home electrical system. These lugs are primarily used for the purpose of connecting cables. Clamps that connect wires to an automotive battery are a simple example of lugs. They constitute two metals- Aluminum and copper. As far as the functionality of these lugs is concerned, copper and aluminium lugs are sort of similar to each other. In brief, they serve the same purpose. The only difference is the nature of the lugs and their application in the system.

What are Aluminum lugs?

Aluminum lugs are the most prevalent and most used kind of lugs. Aluminum lugs are more cost-effective than copper lugs. Aluminum lugs have lower productivity and require higher maintenance. Aluminum is used in many industries. An example of such a sector is energy distribution.

Back in 1960, aluminum was commonly used and was profusely used in each wiring system. Aluminum lugs are easy to install and maintain in good condition. There is a protective coating on them. This coating protects them from shocks and destruction to nearby conductors and equipment. The Aluminum U Lug is one of the four kinds of lugs which is preferred by electricians. These U Lugs are usually used in relays, timers and other electronic devices. A variety of insulation colours and sizes are available. Since all the electric wires are made up of aluminum metal, it is better to use aluminum lugs at the connection juncture.

When aluminum is heated, it expands and contracts and cools fast. Due to the aluminium wiring, lugs can wear out easily and quickly in comparison to copper lugs. One of the drawbacks of using aluminum lugs is that there are too many terminations. Aluminum connection junctures often fail as a result of which electrical fires take place frequently. Aluminum lugs are not considered to be quite safe. Thus, aluminum lugs are not an apt fit for electrical functioning. And thus, copper is regarded as a more reliable and effective substitution.

What are copper lugs?

A copper lug also called a Copper Cable Lug is a significant component of an electrical tool that is used to connect the wire with electrical gadgets such as cables, devices etc. Copper lugs can be used on fuse blocks, distribution blocks, starters etc.

What are copper lugs made of?

All the copper lugs that are available are made of E- copper. E -copper is a sort of copper that has the features of high conductivity i.e it has the ability to handle a great amount of electrical current and also has comparatively high corrosion resistance indicating that it consists of strong resistance against negative elements that can destroy the product.

Why are Copper lugs better?

Copper lugs gained recognition due to the convenience it offers. Copper lugs can end all the issues that are found in aluminum lugs. It does not lead to any hazards that can be dangerous such as aluminum. At present, copper wiring systems are being utilized globally. Copper consists of low resistivity, making it a brilliant conductor. As compared to other metals, it is less oxidative and thus copper does not rust easily. One does not need to be bothered by the rust if copper lugs and wires are used. When direct fastening methods are not required or viable, then copper lugs come useful.

Copper lugs are more reliable than aluminum lugs in several ways. However, copper lugs are not as cheap as aluminum lugs. Copper lugs are still considered more convenient in terms of work or repairing or fixing something. Copper lugs are apt for massive gauge applications such as grounding and power draw.

Application of copper lugs

• Copper lugs are used to connect cables to electrical devices which is one of the chief uses of copper lugs.
• They transmit electrical current between two or more electrical wires. Copper lugs offer the best electrical performance and therefore they are considered the most suitable for high voltage connections.
• Copper lugs can be effectively used in electronic appliances as well as power cable systems.
• There is sufficient safe handling with respect to copper lugs and they are efficiently used in fuse sockets, switches, electrical mechanisms, power circuits etc.
• An electrical tool is connected by a copper lug on one end while the other ends are connected to the terminals of the electrical gadgets.
• The diameter of a thick cable can be reduced with the help of copper lugs in order to attach it to a cable of a smaller diameter.

Some of the areas where a copper lug is extensively used:

Power distribution cabinets – Shipyards, distribution boxes, household appliances, machine room line.

Mechanical equipment factories – factory equipment, electrical equipment factories, metal processing, production processes.
