Heat Shrink End Caps & Sleeves: The Low-Cost Must Use Insulating Power Accessories

Insulating electrical installations in the best possible manner has been the top priority of engineers and industrial consultants. The increasing incidents of accidents and losses caused by poor insulation of cables and electrical components make the use of heat shrink insulation products a necessity. Heat shrink end caps and heat shrink sleeves are two such heat shrink insulation accessories that are affordable to accommodate in any industrial electrical installation. Electrocution kills 12,500 a year; yet, India’s power safety problem finds little attention. Don’t contribute to rising figure of electrical accidents in industries and commercial spaces; instead, plan for your electrical cable installations secured with heat shrink cable end caps, heat shrink sleeves.

Insulating Cables with Heat Shrink End Caps: Importance & Solutions

Cable end caps are crucial part of MV– HV electrical installations because they effectively prevent cables from fraying at the end and leaking current to cause accidents. Reusable heat shrink end caps, one of the important power cable accessories, extend the cable’s lifetime. The heat shrink end caps insulate and seal the cables and splice terminations to safeguard these against moisture, corrosion, chemicals, and abrasion. The leading manufacturers of heat shrink insulation accessories like Gala Thermo offer heat shrink end caps in a range of sizes including 3/8 inches to five inches to set fit at most of cable types and sizes used up 36 KV. INSULCAP cable end caps are available in different categories like   tamper proof application, valved end caps, live end caps, special relief valved end caps, etc. Conductive end caps are also available with conductive mastic cover.

Insulating Cables with Heat Shrink Sleeves: Importance & Solutions

Heat shrink tubes also called as heat shrink sleeves are shrinkable tubes made of Polyolefin having memory effect because of that these shrink radially when heated. The heat shrink tubes are used in different ways and for different objectives related to improving lifetime, protection, insulation, performance of wires and cables in electrical installations. These offer dependable protection to cables from abrasion, environmental impacts, corrosion, cutting, scuffing, and usage impacts. Protection against humidity and temperature increases lifespan of cables and sheathed components.

The maximum and minimum perimeters of the cable are the major selection parameters. The commonly available shrink ratio options are 2 to 1, 3 to 1, and 4 to 1. The length of heat shrink sleeves gets reduced 5-7%. Polyolefin heat shrink tubes can withstand temperature of 125°C – 135°C. For extra bonding and protection, adhesive lined heat shrinks tubes are also available. The leading manufacturers of heat-shrink power cable accessories offer a custom-to-need range of heat shrink tubes in different categories. Some popular categories are GDW dual wall tubing with 3:1 and 4:1 shrink ratio; medium / heavy wall tubes -Insultube commercial suitable up to 36KV cables; heat shrink co-extruded tubing premium for insulating underground and aerial connections; heat shrink bus bar sleeves for up to 36 KV; Red Insulation Tubes – INSULTUBE Red for MV applications; and stress control tubes to control electrical stress.

End Note

Innovation to provide better than the present heat-shrink insulation accessories for electrical installation is a continuous process at the top brands of heat shrink power cable accessories manufacturers like the one Gala Thermo. A slight investment with human centric approach to safeguard the workforce and establishment may contribute to your business growth rate.
