The heat-shrink power cable accessories are drawing wide scale attention of engineers, industrial consultants, contractors, technicians and others because of being a cost-effective solution to reduce accidents. Though the technology exists since decades but the increasing incidents of accidents because of short circuit, improper electrical insulation, current leakage, inaccurate connections, exposure of live-current cable ends, etc are making heat shrink cable joints, heat shrink tubes, heat shrink moulded shapes, and other accessories in high demand.

What is Heat Shrink Technology? How Reliable is it to Reduce Electrical Accidents?

Heat shrink technology has been around for over 60 years; most of us have used heat shrink products in one way or other but without paying attention over the technology involved. Today, heat shrink technology has become an indispensable part of the power cable industry. Elastic memory concept is used in specially formulated thermoplastic polymer materials to develop heat shrink electrical power cable accessories. Heat shrink materials have the modifiable ability to adapt a temporary shape on being heated and then back to their original shape to different degrees.

Resistance to thermal ageing, flame retardant, high thermal property, erosion resistance, hydrophobicity, resistance to on the surface electrical activity, excellent abrasion resistance, adhesive-lined insulation, excellent chemical resistance, etc make heat shrink cross-linking polyolefin polymers the perfect material for electrical insulating accessories. Dielectric Strength is more than 15kV /mm and Dielectric Constant is 3.0 (Max.). The polyolefin materials can withstand up to 105°C temperature. The heat shrink power cable accessories in compliance with IEC 60684-3-247 standard are time-tested insulation for low to 3.3KV.

Is It Easy & Feasible to Use Heat Shrink Moulded Shapes & Heat Shrink Tubes?

All the first time users of heat shrink products have this question in mind. The leading manufacturers of heat shrink moulded shapes and tubes, like Gala Thermo offer application-ready solutions. The heat shrink moulded shapes get fit over various components of electrical installations. Internally coated with hot melt adhesive, heat shrink low voltage cable breakouts provide 100% water/moisture proofing to the connection according to IP 68 (For reference, you can refer Technical Qualification Report No.: QR 1012). The ever-expanding product-line of heat shrink moulded shapes includes- cable end caps, cable end sealing caps, de- gassing end caps, live end caps, PVC Caps, low voltage breakout, anti tracking breakout, semi conductive cable breakout, rain sheds, right angle boot, straight boot, etc.

Similarly, heat shrink tubes are available in different categories to suit the electrical installation of different voltage range – low, medium, and high. Using medium / heavy wall tubes is a perfect solution for environmental protection of low voltage cable terminations. These are ideal insulation for low voltage straight through joints/splice rated up to 3.3KV. Gala Thermo, the top manufacturer, supplier, and exporter of heat shrink tubes offer maximum cut length up to 1500 mm. A range of options is available for thin wall heat shrink tubes also- GSC: Flame Retardant Tube, GSC/YG Series, GLC Series, and GLC3: Commercial Grade Tubing.

Pro-Note

All the heat shrink cable joints, heat shrink moulded shapes, and power cable accessories come with the instruction book detailing about how to use these ensuring the maximum insulation protection. Gala Thermo, the top manufacturer and supplier of heat shrink accessories, provide online guidance also to help you buy the right product and use it in a right way.
