The place of cable accessories cannot be undermined in any power distribution system. Cable accessories play an important role of connecting and securing differently sized and shaped cables and offer total protection to the internal and external power equipment.

A wide variety of cable accessories exists in today’s times with several entrepreneurs involved in their manufacture. All of them provide high quality cable accessories in order to ensure better performance and stability of the entire power network. These accessories are tested on a series of parameters by the manufacturers for ensuring their perfect working. Besides the standard cable accessories, the manufacturers also offer customized versions to suit specific requirements of the customer. Customized versions include accessories made from special materials and odd sizes. Some components that form part of cable accessories are cable end caps, cable breakout boots, medium wall tubing, medium voltage insulation tape, breakout shapes/boots, cable repair sleeve etc.

Cable end sealing caps are one of the most important items of cable accessories kit and rightly so! The number of advantages offered by them are plenty with the greatest being lifelong protection to cables from weathering, dust and moisture contamination. They offer long term and reliable environmental sealing to regular power and telecommunication cable types. Unused ends of electrical cables that are connected to electric supply are insulated by cable end caps which come in different materials. They can be easily installed in small spaces and they go with different types of cable jackets. Optimum performance is thus guaranteed under severe environmental, thermal and electrical stress by use of cable end caps of good quality.

Cross linked polyolefin is normally used for the manufacture of cable end sealing caps and this is lined with an adhesive besides being thermally stabilized to enhance its protective sealing capacity. The raw material is smeared with chemical additives and this provides extra protection against oxidation, ozone or UV radiation. Sometimes semi-conducting or non-tracking materials of high voltage are used in the manufacture of cable end caps. In order to make the high voltage non-tracking variety water-proof, insulating and non-tracking it is coated with butyl rubber mastic. For the semi-conducting variety, a coating of semi-conductive mastic or a poly-amide based hot melt adhesive is given or a suitable blend of the two may be used. Telecommunication cables that are pressurized require film form coating for their cable end caps whereas the non-pressurized telecommunication cables require spiral form coating. One of the most useful varieties of these end caps are the heat shrink cable end caps. These offer insulation to insulated wire and cable ends that are cut and exposed. The heat shrink type is available in several shrink ratios and is therefore suitable for cables of differing diameters. In addition to the end caps, the other items that go under cable accessories also have an important role to play in the electrical systems.

Whatever, cable accessory you choose, it is very essential to approach a reputed manufacturer who makes them from sturdy materials as only they stand the test of time.
