Cabling work in industrial setups having harsh environments needs extra protection for long-term fault-free performance. Heat shrink tubes and corrosion protection tubes made of polyolefin to give a 2:1 or 3:1 shrink ratio protect the cables in extremely harsh industrial environments having the presence of chemicals, moisture, gases, high temperatures, etc. Selecting the right tubing size is crucial. Sizes of heat shrink sleeves/tubes are denoted as a ratio of expanded size; for example, a tubing with 3:1 shrink ratio shrinks to 1/3 of its original diameter; similarly, 2:1 ratio means the tubing will shrink to half the size of its original diameter when supplied.

Applications-Ready Heat Shrink Tubes for Electrical Cables Protection

The success of industrial setup highly depends upon the smooth performance of electrical cables because it directly reduces downtime and maintenance costs. Fault-free electrical cables contribute to success in achieving estimated production rates at optimal cost. Therefore, new electrical installations are designed with advanced protection techniques; and, using corrosion protection heat shrink tubes is one of those practices. Additional protection against all the odds is achieved by using application-ready heat shrink sleeves-

• GSC : Flame Retardant Tube
• GLC: Commercial Grade Tubing
• GLC3: Commercial Grade Tubing
• GDW : Dual Wall Tubing (co-extrusion of polyolefin and hot melt adhesive)
• Medium/Heavy Wall Tubes-Commercial (To be used in critical areas like tunnels / mines)
• Heat Shrink Co-extruded Tubing (Used for corrosion protection and insulation of underground & aerial connections)
• Red Insulation Tubes (Used in power cable joints for MV applications)
• Non Tracking Tubes (Used to achieve anti-tracking performance and corrosion resistance)

Reliable Insulation & Corrosion Protection by Heat-Shrink Sleeves

Available with shrink ratio 3:1 or 2:1, heat shrink sleeves meet RoHS compliance as well as other world-class standards like ASTM, IEC, MIL-1-23053/5 Class 2, CSA C22.2, IP 68, etc. The dielectric strength of these sleeves is more than 15kV / mm while the dielectric constant is around 3.0. Water absorption is about 0.15%. The leading manufacturers of corrosion protection heat shrink tubes, like Gala Thermo in Mumbai, use MIL-1-7444 testing practice to check fungus resistance, ASTM-D-2671-B testing practice to check copper corrosion, and ASTM-D-2671 testing practice to check chemical resistance. When heated, a heat shrink tube provides a tough but flexible water and chemical-resistant cover around the cable to keep it protected against the concerned environmental challenges; may it be corrosion, vapors, gases, moisture, mechanical impacts, exposure to sunlight, etc.

Is Heat Shrinking Really A Good Technology To Adopt?

Available up to 36 KV, heat-shrink corrosion protection tubes are available in custom-to-need specifications also. The key selection parameters are internal diameter (supplied and recovered), recovered wall thickness, cut lengths, and suitability to a particular voltage range. These are available in a variety of colors for easy coding and identification which saves time during maintenance; the standard colors offered by prominent top suppliers and exporters of heat shrink tubes are black, white, yellow, red, blue, green, and clear. The professional appearance that you miss otherwise also advocates adopting heat shrink technology for cable protection in tough conditions. The investment you make in buying corrosion-protective heat shrink sleeves comes back to you in the form of reduced maintenance costs, high production output, fewer accidents, additional safety for workers, etc.
