Cable joint kits are instrumental for most electrical distribution networks. They are typically used for the repair of damaged cable sections or to extend the existing cable to use it with other applications. These kits come equipped with a variety of cable joints, each with its distinctive features and function.

Here’s the list of different types of cable joints used in electrical networks. 

Heat shrinkable type:

This cable joint is made of a plastic shrinkable tube, mostly used for electrical insulation to provide environmental protection and make seals for cable entry. The heat shrink tubing material is either polyolefin or nylon that shrinks radially and not longitudinally. In this, wires or cables are uncovered and twisted one-on-another before applying the heat shrink. 

Tapex type:

It is a simple cable joint that includes twisting the wires and covering the joint with tape. In the process, wires are first stripped, then exposed wires are twisted one over the other as a rat-tail joint or a western union straight joint. When there are more than two wires use knotted tap joint. For this, trim the ends and lastly, tape the bare wires.

Tapex type outdoor termination cable joints offer higher insulation and help achieve continuity of semiconducting layer and control the stresses at the cut end of the screen. 

Slip-on type:

The easiest type of cable joint, a slip-up is used on the field with tubing inserted first, and then the wires are put in the joint. The slip-on tube is pushed in place and fused for the application. 

Pre-molded:

As the name suggests, this cable joint has pre-molded one-piece sleeves with good electrical and mechanical properties. It is made of ethylene-propylene rubber material that provides suitable insulation while holding the mechanical strength to keep the joint fixed. Pre-molded joints are used in tunnels and underground applications. 

Push-on:

Push-on cable joints are known for their reliable and durable life. They cover the cables that you can push on once the joints are made. These are used for all cross-sections of cables and are much in demand due to their high weathering quality and applicability in outdoor environments. 

Conclusion: 

To ensure the quality of the electrical connections, you need to use a proper cable joint. A mismatch can lead to damages and breakdowns. When you are procuring cable joints, be mindful of getting superior ones for longevity and safety.
