Parting Note

The practice of using low-cost heat shrink cable joints for secured cable connections saves a lot in the long-term in the form of low maintenance, long life of electrical cable connections, reduced faults in electric supply etc; adapt heat shrink technology for growth-oriented transition in a new era.

The importance of insulation accessories for electrical installation can’t be undermined because making the electrical installation human safe is the top priority after the other major concerns like uninterrupted power supply, long life, low maintenance, minimum shut-down periods etc. Sensing the increasing acceptance of importance of cable insulation accessories, manufacturers are producing a range of cable insulation accessories; and, the heat shrink cable end caps are the low cost but highly useful often neglected accessories.

Heat Shrink End Caps- A Must Have Insulation Protection

As the name denotes, end caps are used to insulate cable ends. What will happen if you don’t use end caps? Taping the cable ends is a conventional practice but it is not effective for longer period especially in industrial and complex electrical installation. The normal PVC tapes don’t provide protection against environmental impacts; neither, these make the cable ends water/moisture resistant. Most of times, the PVC tapes become loose because of environmental impacts. PVC tapes are not good to resist mechanical stresses also that are very common in industrial installation. The use of electrical cable end caps provides a reliable long-lasting protection cover to cable ends.

Heat Shrink Cable End Caps Are Easy To Use

The increasing acceptance of heat shrink technology worldwide denotes that the heat shrink electrical insulation accessories are really effective to protect the installation and humans both from shocking incidents, cuts, and other hazards. The leading manufacturers of heat shrink cable end caps like Gala Thermo offers guarantee for optimum performance under severe environmental conditions and electrical stresses.  The use of cable end caps does not need any specific training; the manual automatically guides to use these small but must use accessories. Cross-linked polyolefin is the most used material. The adhesive layer inside the cable end caps keeps these sticked permanently. The shrinkage on heating property makes these caps tight around the cable ends; so, there is no harm to cable functioning because of water, dirt, moisture, chemicals, gases etc.

The Variety of Cable End Caps

Whatsoever kind of cable you might be using, Gala Thermo offers a perfect fit solution to seal the cable ends. The readily available range of cable end caps suits to XLPE, PVC, PILC or rubber sheathed cables.

Valved End caps are available for pressurized applications like in Telecom cables. Special Relief valve End Caps are available for degassing applications like in HV power cables. Live End Caps are available for sealing the live cables. Conductive cable end caps are also available with conductive mastic sealant. Cable end caps marked with custom logo created with non- removable ink delivers extra security and higher standards for electrical installation.

The key parameters for buying heat shrink cable end caps are – density, tensile strength, ultimate elongation, water absorption, accelerated ageing, shrink temperature, temperature limit etc. The parameters like dielectric strength, volume resistivity and dielectric constant etc decide the suitability according to a particular electrical installation.

Concluding Note

Heat shrink cable end caps are available in three categories- Live end cap kit, de gasing end caps, and cable end sealing cap (INSULCAP).  IP 68 is the ‘Ingress Protection’ standard that you should not miss to confirm.

Human safety against electrical installations is the top concern of electrical engineers and consultants.  All the best practices are applied to make electrical installations safe against all the possibilities. Insulation quality plays a vital role in making the electrical installations safe as well as long-lasting performing. The heat shrink electrical insulation products innovated and produced by Gala Thermo are getting high-end popularity because being application-ready and user-friendly.

Need for Heat Shrink Electrical Insulation Products

The insulators have been one of the most neglected elements of electrical installation in industrial sites. Most of the times, we forget about these until they fail to cause heavy loss. Contamination and water are the most powerful enemies of electrical insulation. Contamination creates a path of less resistance for isolated voltage to cause electrical breakdown and heavy loss. Water moisture penetrates the insulator´s body and other elements of electrical installations to reduce insulation capability for voltage isolation. The conventional insulation solutions are cheaper but these are not as effective as they should in challenging environments and working conditions. Here, heat shrink electrical insulation products being manufactured, supplied, and exported by Gala Thermo, win the trust of electrical engineers and industrial consultants.
