Making Your Medium Voltage Cable Joint Secure and Stable

When an old cable undergoes damage and needs a replacement you will need several things. One of the most important things is the cable joint tools. Cable joints are an indispensable part of the electrical distribution network. You can replace a cable with a new one or extend an existing one by cable jointing.

Things we need to make the cable joint

You use only standard tools to make the cable joint. This would consist of the cable strippers and cable sheath jacket stripper. Then, you need semi-conductive screens and cable insulation removers. However, we have many types of medium voltage cable joints and we see how they differ from each other.

Various types of joining cables

We can do the jointing of the cables with different material. Each of them has its uses and drawbacks.

Use of the tape

The tape is an effective way to make connections. You can use the tape at almost any place you want. The size of the cable does not matter and you can use any brand of tape since they have the same properties. The only shortcoming is that it takes a long time to wind the tape over the entire splice. The effort needed is much more than normal. If the person doing the cable jointing is not careful in his work, the quality of the joint will be poor.

Use push on

You can make joint with a push in less time than if you were to use a tape. These splices are factory tested and have standard strengths. However, you will require a special connector to make the push on. For this reason, this type of jointing is not applicable for all connections. You must knowledge of the cable and its properties before you undertake to make a connection. Further, one should have enough space on the cable to use the push on. One must use asymmetrical cutbacks for the push on.

Use heat shrink

The push on splice restricts the number of applications for which you may use to make the joint. The tape process is laborious. One a comparative note, you may use the heat shrink in more places and the work involved is not tedious. One uses the torch to make the joint and this restricts the usage a bit. In places, where the use of a torch is risky, you cannot use this joint. You need good workmanship as the application of the heat must remain uniform.

Cold shrink methods

We do most of the cable jointing through the cold shrink method. This kind of splice keeps the pressure on the cable and the connector. You can make a joint under any weather conditions at any place. Most of the work is already done and you need not use a torch for this. The only criterion is you should have the space to use the splice.

When making the choice of the type of splice you make for the cable, the conditions you check include worker safety, cost, value, and reliability. You must consider the cable types and the voltage class. Added to this, you consider the fault duty, bonding needs, and environmental variables.
