Splicing Kits and Process of Cable Splicing

Splicing-Kits-and-Process-o

Splicing kits help to make repairs to cables or add extra length to them. Splicing is the process where the two ends of the cable are joined. Typically, electric cables have twisted pairs of conductors shielded. A copper drain is provided alongside. There are many kinds of cables such as vented cables or reinforced cables.

Instance of splicing

When one splices with a kit, one uses a sleeve made of PVC or stainless steel. This sleeve is entirely watertight. One must resort to splicing only when there is no other option. The spliced cable is not as watertight or solid as the original cable.

When one uses electrical equipment in area where lightning is heavy, one has to make sure there is adequate lightning protection. Grounding methods for all the instrumentation, adequate surge protection, and providing shielding for wiring will help to deal with the problem of lightning. One can add gas tube surge protectors if needed.

Uses for the kit

This is used to connect a whole range of applications existing in different environments to the electrical transducers. The cables need splicing using the cable splicing kit. The cables could be shielded twisted pairs of 2 to 12 conductors. They have an outer covering of polyethylene, PVC, polyurethane, or rubber.

Splicing the cable

One may identify the different cables by their model and cable length. The cables may be armoured or unarmoured. The cables are stripped from 4” to 6”at the ends. The conductors are cut in staggered pattern so that the joints do not come near each other. The exposed conductors must be of 3/8”.

Crimp butt connectors to the first cable. Then crimp the butt connectors to the second cable. Twist the cable without any force and put inside the mould. Place the other half of the mould over the first and snap shut. Wrap scotch tape over the ends of the mould.

Now place pouring spouts on the mould body. This is to pour the epoxy resin into the mould. The epoxy must be mixed in the specified ratio only. After pouring, the mould is allowed to set. Then you can remove the spouts.

Types of cables

Usually in a cable you have a conductor or several conductors covered by an insulating sheath. Several conductors are placed inside one common cable jacket. You have different cables as given below:

  • Non-shielded dry cable
  • Non shielded wet or dry cable
  • Single conductor portable cable
  • Multiple conductor portable cable
  • Concentric neutral cable
  • Jacketed concentric neutral cable

Cables could be classified according to their application as:

  • Electrical cables
  • Telecom cables
  • Fibre optic cables

The electrical cable could belong one of the types given below as:

  • Direct buried cable
  • Flexible cable
  • Paired cable
  • Multicore cable
  • Metallic sheathed cable
  • Non metallic sheathed cable
  • Ribbon cable
  • Portable cord
  • Submersible cable
  • Communication cable
  • Shielded cable

Hybrid and optical cables find use in fibre-to-the-antenna applications. Here the electrical conductors carry the power while the fibre cable carries the data to be conveyed. The voltage used is nominal however this depends entirely on the application. Because of the variation in the levels of the signal and the power carried in the cables, this type of cable is termed as power cable.
