Different Types of Connectors Used in Electrical Networks

Product Description

In the electrical industry, the term termination means that point at which the conductive device begins or stops. This conductive device may be a cable or a wire. The need for a termination is to either extend the cable or to make repairs to it.

You need to choose the proper termination to make an effective connection in the electrical circuit. Here we look at the different types of connectors possible in electrical circuits.

Twist on connectors

First in this group is the wire and nut wire connectors. This has a spring inside that one may thread lightly for providing a reliable grip. The plastic is of self-extinguishing type. The second is the wire connector that is made of hard plastic. These shells are fire retardant and have a square steel spring to improve the life of the connector. The last one is the screw type wire connector. These are designed to hold 2-4 wires at a time. They are simple to use and have good safety and durability.

Splice connectors

You have many types of splice connectors. These save you time and effort since you do not have to do much work. The inline splice connector needs you to insert the wires and then slip the splice into place. The second type is the jelly-filled splice connectors is similar in the functionality. They have jelly in the joints to help make the joint better and improve the insulation.

 

Heat and cold shrink terminations

The heat and cold shrink joints find use in medium voltage cable terminations. In the heat shrink method, the splice is slipped over the joint and a torch is applied. This fuses the splice in place. The drawback of this method is that you might have places where you may not have the permission to use a torch. The alternate in this case is the use of a cold shrink joint.

In the cold shrink joint, we joint the ends of the cable and use a splice to keep it in place. Once the joint is secured, we use a pre-tensed sleeve over the splice that now tighten in place over the joint.

Lug connections

First, we have the compression lugs made of copper or aluminium. These helps improve the electrical connectivity. You can make precise cable terminations using accurately marked crimping points. Next in line we have the mechanical lugs. You can get these lugs in aluminium and copper as per the conducting material you use. They have shear heads that come apart as soon as the needed torque is reached in the head of the lug.

This way, you need not carry a torque measurement tool for making precise connections. For making connections where you have water, you use the buried power connectors. These provide reliable grounding and finds use in HVAC, solar applications, and swimming pools.

Push connectors

The push-in wire connectors are reliable, easy to use, and provide an easy means to make electrical connections. You do not require special skills as the operation is a simple push that anyone can do. You can use colour coding to indicate the wire rating. The higher variation of this type uses the same principle but has more cover for the joint.

Making an effective joint is imperative to providing a safe and dependable electric distribution system. Always use industry standard equipment so you have safety.
