Power cables are widely used in various electrical systems. Whether they carry low voltage or high voltage, their protection and safety are critical. When connecting power cables from one terminal to another or to equipment, there are a lot of safety considerations. Sealing the end cap, insulating the switchgear, core separation, sleeving, taping, etc. Therefore, there are a lot of cable termination accessories used whenever a cable is drawn and attached. In this blog, we are going to discuss why these are important and throw light on some of the main types.
Types of Cable Termination Accessories
Depending on the voltage levels, insulation, protection from environmental factors, and other factors, there are several types of power cable accessories. Here is the list of the main types:
- Connector
These physically link the electrical conductors to facilitate power transmission between the ends of a circuit. These are terminals, junctions, plugs and sockets.
- Terminations
The terminations are heat shrink or cold shrink, whichever is suitable. These are used to terminate the cable at the equipment, a junction or a terminal. The process may involve a speed gun in a heat-shrinking method. This is to secure the termination of the cable.
- Joints
The joints are used to connect two cables or wires to extend the transmission cable, repair it, or branch out. These are corrosion-resistant and have an unlimited shelf life.
- End Caps
These caps are used to close the open end of the cable when they are not being used. These protect the cable from dirt and moisture when being stored or transported.
- Tape
These are adhesive tapes used for insulation, protection, and identification of cables and wires to prevent electrical hazards.
- Gland
It secures the entry point of cables and seals the ends. It protects the cable from straining and pulling, providing mechanical security.
Importance of These Accessories
Cable termination accessories are important for several reasons. Firstly, they ensure electrical safety and the integrity of the connection. They safeguard the system from electrical failures that may be caused by loose connections or open ends. The stress at the joint is high compared to the rest of the cable, so it is distributed by one of these accessories. Secondly, these create an identifiable barrier between the different connections. Separate connectors for terminals, motors, switchgear, etc., are necessary for identification. Lastly, these help in ensuring the electrical system meets regulatory compliance.
Conclusion
To summarize, cable termination accessories are critical in securing connections, providing insulation and protecting the electrical system from damage. The purpose of these accessories is to protect, insulate and secure connections. These facilitate the power transmission by connecting the joints safely and terminating the cables. Some of the other accessories are bus sleeving, right-angle boot, straight boot, bus bar taping, etc. The heat shrink and cold shrink methods are two popular methods used in joining and terminating cables.
