Heatshrink Tubing and Shapes

Heatshrink Tubing for Electrical Insulation & Corrosion Protection

ISP has developed a complete range of Heatshrink Tubing for the insulation of electrical connections and bus-bars ranging from 600 Volts to 36,000 Volts for both indoor and outdoor applications. All products are tested, certified and conform to international quality and performance standards: UL, BS, IEC, DIN, ASTM, ISO and Military specification.

Commercial Grade-E

hsp3  

Flame retardant thin-wall heatshrink tubing is excellent for insulation of electrical connections and bus-bars for low voltage (<600 Volts) applications. Features:

  • High temperature rating up to 125 degree C
  • High flexibility prevents wrinkling when bent
  • Excellent insulation capability
  • Highly flame retardant / self extinguishing (VW1)

Specifications: UL-224, 125 degrees C, VW1, CSA C22.2 No. 198.1, OFT

Medium & Thickwall Heatshrink Tubing

Ideal for:

  • Aerial & underground outdoor low voltage installations (0.6/1kV) - cable terminations, joints, cable duct enclosures, etc.
  • Thermoplastic adhesive lining provides excellent waterproof and moisture-proof seal
  • High resistance to decay, chemicals and corrosion

Specifications: Certified to BS6910: Part 1: 1988, Flammability conformance: ASTM-D-2671

  

hsp2

Anti-Tracking Heatshrink Tubing

hsp5  

Specially developed for insulation of bus-bars, bus-ducts and cable joints in medium voltage environment. Applications:

  • Insulation for bus-bars in switchgears and related equipment in outdoor substations
  • Safety protection against accidental bridging and environmental corrosion

Specifications:
DIN VDE 0303 Part 2 (Dielectric strength)
DIN VDE 0472 Part 602 (Tensile strength)
DIN IEC 112, IES 587 (Resistance to tracking)

Heatshrink Tubing Specially Designed for Wire Harnessing Applications

ISP range of thin-wall and dual-wall tubing are excellent for light and heavy duty harnessing applications. These products provide good insulation and protection for in-line components, terminals and splices. They are also ideal as strain-relief for electrical wire connections, bundling of wires and colour coding of cables.

Commercial Grade Tubing

hsp4  

This is produced from a specially formulated crosslinked polyolefin material with the following characteristics:

  • Low shrink temperature
  • High flexibility
  • Excellent insulation capability
  • Highly flame retardant / self extinguishing (VW1)

Specifications: UL-224, 125 degrees C, 600V, VW1, CSA C22.2 No. 198.1, OFT

Dual-Wall Polyolefin Tubing

With thermoplastic adhesive, this tubing environmentally seals and protects interconnections in a wide range of electronic, electrical and communications applications. Features:

  • High shrink ratio (3:1 and 4:1)
  • Excellent water and moisture proof
  • Excellent electrical insulation and mechanical protection
  • Highly flame retardant (Mil-1-23053/4 Class 3)
