Heat shrink insulation technology is a specialized designed method used to provide robust electrical insulation and protection for various components and connections in electrical installations and industrial mechanical settings. This technique involves the application of heat-shrinkable polyolefin materials made from cross-linked polymers that tend to shrink when exposed to heat. On being heated up to a particular temperature, these materials shrink tightly around the object they are covering, creating secure and durable insulation against environmental factors such as moisture, dust, and mechanical stress. Time-tested heat shrink technology in being embraced globally with a consistent rise in demand for low-cost heat shrink insulation products like heat shrink end caps, cable terminations, heat shrink tubes, etc. Easy to accommodate on a budget, the heat shrink insulation products enable you to save on many accounts besides making the environment safe for workers. In this blog, I will spill the beans about easy-to-use cable end sealing caps, cable terminations, heat shrink sleeves, and power cable insulation cable accessories.
What Are Heat Shrink End Caps Or Cable End Sealing Caps? In professional settings, heat shrink end caps are widely used by electricians, engineers, and technicians to ensure the integrity and longevity of cable terminations. By using heat to shrink the end caps, a secure and waterproof seal is formed, safeguarding the connections from potential damage and ensuring reliable performance. The heat shrink end caps provide a protective covering for the ends of cables, wires, and other objects, offering insulation and sealing against moisture, corrosion, and other environmental factors. The leading manufacturers of heat shrink insulation products offer a comprehensive range of heat shrink cable end sealing caps to secure cable terminations-
De gassing End Caps: De gassing end caps are designed with Relief Valve (RV). These are used for sealing the terminations of high voltage and extra high voltage cables to release the gas generated inside the cable during transportation and storage because of hot climate conditions. De gassing cable end sealing caps provide additional security to cables by relieving the pressure developed by residual gases.
Live End Caps: Live cable end sealing caps are used to seal the live cables by sealing each core separately. By sealing each core separately, the outer heat shrink cap is applied.
What Are Heat Shrink Cable Terminations? Heat shrink cable terminations are used for indoor and outdoor LV-MV-HV power cables. High-quality heat shrink cable terminations are lab-tested for having excellent strength and resistance to solvents, chemicals, & extreme temperatures. Some easily available variants of heat shrink cable terminations are GLT – 1100 – Series, GXO/E – 1112, GXOS/E – 1236, GPO/E – 1112, and others.
What are Heat Shrink Sleeves? Heat shrink sleeves are widely used in various industries to provide long-lasting protection and insulation for electrical and electronic components, cables, and connections. Made from polyolefin, these offer excellent insulation and protection against moisture, chemicals, and abrasion. Leading manufacturers of heat shrink tubes offer an application-oriented range of thin wall flame retardant tubes, dual wall tubing, medium/heavy wall tubes, non-tracking tubes, and others.
Besides the above, the commonly used power cable accessories include heat-shrinkable joints, insulation enhancement products, heat shrinkable moulded shapes, heat shrink boot, busbar tubes, etc. The numbers of manufacturers of heat shrink power cable accessories offer industry-specific solutions; one of these is Gala Thermo. Gala Thermo Shrink Pvt. Ltd., established in 1979 has proven specialization in manufacturing and supplying heat shrinkable range of insulation products.
