In industries, high voltage electricity is used extensively for many different purposes. In order to hold such high voltages of electricity, there are very sturdy and string electrical networks installed in industries. Without a string electrical system, no industry can survive for long time. It is the electrical system of the industry that supplies the power to the machineries of the industries to run them. For this reason, it is very important to take care of the industrial electrical networks and its components.
When the components of a high voltage electrical network work under such high voltages, there is a heavy stress that they have to bear continuously; hence they suffer wear and tear more than normal circumstances. For this reason, only the best quality electrical components should be used in any high voltage electrical network of an industry. Good quality of the components is also important for safety of the system, as well as the people who are working on that system.
One major component used in industrial systems is the cable jointing kits. When there is a joint made between two cables, the joint is weak and needs extra protection so that it could not be damaged from outer factors such as environments, chemicals, mechanical forces and stress due to cable weight.
Compaq is one of the finest cable jointing kits manufacturers in India The cable jointing kits offered by Compaq offer you the best solution for the protection of the cable joints in your electrical systems. The Compaq cable jointing kits are available in both heat shrinkable and cold shrink types and suitable for both single core and triple core cables. The working range of Compaq cable jointing kits is also very wide and starts from 3.3KV and goes up to 36Kv.
