Use of Cable Joints in the Splices Make the Right Choice

Product Description

Cable splices help you make the needed extensions to the existing cable. This is needed in electrical networks to extend it. Other times, you use it to make repairs when the cable has suffered damage.

Conditions that influence the selection

The criteria for selecting the type of splice to use depends on the purpose and related factors. Safety of the workers, reliability, and cost of the life cycle are the next things one must take into consideration. You must check the cable type and grounding. The bonding requirements, fault duty, and voltage class make up the rest of the needs you must check.

Use simple to join cables

When selecting the brand one needs to see how complex the instructions accompanying the cable is. You should cable jointing accessories to make the splice. One might have to undertake complex operations even when the instructions remain simple. Though one may use different installation methods, one must consider installation and environmental variables.

Use of tapex

The common types of splices include use of tapex, which is common but not used in places where you have no time or need more safety. The work is tedious though there is enough safety. The other methods such as the heat shrink, the cold shrink, and the slip-on types of splices give more safety. In addition, the work involved is lesser.

Heat shrink and cold shrink splices

The heat shrink splice kit has a sleeve that you slip on to the joint after you have twisted the wires together in the desired fashion. Applying heat with a torch will shrink the sleeve on the joint and provide the protection. In the cold shrink splice, the method is similar except there is no application of heat.

The advantage of the cold shrink splice is that one may not be able to use the torch in all places. Other times, there may not be enough space to work with the torch. The tension in the cold shrink tubing will prevent water from seeping in and the joint becomes water proof.

The slip-on splice

The sleeve in the slip-on cable joint is pre-tensed and then placed over the joint. When the tension is released, it seals the joint. In this respect, the slip-on is the best and easiest joint to make. You don’t have to use heat or tension.


Check the specifications

You get a high degree of safety when you use silicone insulators in the electrical installations. You can use these insulators for the voltage range 11-36 kV. For more details, you should contact the silicone insulator manufacturer and supplier website. Look for those manufacturers who have ISO certification since then you are sure of the quality of the product.

Use of the tool kit

The other things you need when making a cable splice is the tools kit. This will include the cable sheath jacket stripper, cable insulation remover, semi-conductive screens, and cable strippers among other things.

The reason for the failure or success of the cable splice depends on the skill of the worker and the effort he puts into the work. Poor quality workmanship often results in the failure cases. One must use high quality tools or it could result in an improper cable splice.
