Guide To Understand Heat Shrinkable Cable Termination and Joints

 Cables across the vast electrical and telecommunication network play a key role in our lives. Many aspects of our daily activities are dependent on the quality of cable and how they are distributed. As the power flows from the generation end to the consumer end, there are a large number of cables in a huge number at successive points. In the vast network, there are junction points such as transformers, switchgears or poles. These are the terminating points of the cables. If you are wondering why this is important for our topic, these are the very points at which the Heat Shrinkable Cable Termination is used. Yamuna Cable Accessories is a reliable manufacturer of power cable termination and joining essentials. In this blog, we are sharing our insights on the various aspects of termination and joints.

Why is Heat Shrinkable Cable Termination Needed

When the cables need to be joined to the terminal, load or equipment, it is called termination, while joining two or more cables is called joints. The cables' ends in either case are open, making the current flow poorer and dangerous also. The ends can’t be laid open else it can cause serious accidents. Heat shrinkable cable termination is a method to cover the cable ends. These are used to tighten the joint, prevent moisture, chemicals, and dust from entering the connection, and prevent accidental contact.

This termination kit has tubing, stress control mastic, anti-tracking tubing, sealant, and accessories such as lugs, tape, cleaning solvent, worm clips, and an end cap. The steps in this method are performed by experts. The cross-linked polymer shrinks under the influence of heat, which creates a tight seal on the cable end. Before applying the heat tubing, the cable end should be stripped of insulation and cleaned. The application of a heat gun must be done with a focus on uniform heating.

Properties of Heat Shrinkable Cable Termination

●     The material of heat shrinkable cable termination has high dielectric strength. Due to this, it is able to prevent electrical arcing, corona discharge, and short circuits in low to high-voltage environments.

●       Water and moisture can cause short circuits and fire accidents; therefore, they must be prevented at any cost. The strong, leakage-proof sealing created by the cable termination is watertight, which doesn't allow any moisture and other contaminants from contacting the cable conductor.

●       There is a certain stress at the termination points, especially at the high poles. These put strain on the cable points. Other forces like abrasion, impact and vibration can also damage the function of cables. But with the shrink tubing, sufficient mechanical protection is given.

●       Harsh temperature conditions, winds and other environmental stressors are dealt with by the termination. Overall, this method makes the joints and terminations safe, durable and long-lasting.

Conclusion

Heat shrinkable cable termination is the method of using a polymer that shrinks under heat on the cable terminals and joints. This is one of the most popular methods for safeguarding the cables from stress, water, environmental factors and electrical faults. These have high dielectric strength and tensile strength.
