New heat shrink tubing from Amphenol used in transmission, distribution and insulation protection

10 March 2015

Amphenol Industrial Products Group, a global leader in interconnect systems, has introduced a new line of heat shrink tubing for the electronics, energy, rail mass transit, heavy equipment, hybrid/electrical vehicles, telecommunications, mining and oil and gas markets.

The RoHS-compliant Amphe-HST (heat shrink tubing) is widely used in low-voltage applications and medium-voltage transmission and distribution, as well as insulation protection.

This new HST line comes in a variety of styles including thin wall tubing to protect all types of electronic and electrical applications and dual wall tubing that seals and insulates splices, junctions, Ys and Ts, back shells and terminations where environmental protection is required.  In addition, our high temperature products operate in environments up to 260°C. Medium and heavy wall tubing for energy markets, as well as medium voltage tubing and tape for bus bar applications are also available

The UL/CSA-certified thin wall tubing has a maximum operating voltage of 600 V and an operating temperature range of -55°C to +135°C.  It is offered in multiple colors, has heat shrink ratios of 2:1, 3:1 and 4:1. It comes in flame retardant and non-flame retardant material as well as halogen free or low smoke option and is resistant to common fluids, solvents and UV rays. It’s available in multiple colors and in flame retardant, non-flame retardant, UV resistant materials with the dual wall tubing featuring the same maximum voltage, operating range and certifications as the thin wall tubing. It also meets SAE-AMS-DTL-23053/4 and has heat shrinking ratios of 3:1 and 4:1. 

Amphe-HST’s medium and heavy wall tubing have a voltage range of 1 kV to 36 kV and an operating temperature range of -55°C to +110°C.  The tubes are UV and oil resistant, halogen free and give stress control as well as high insulation.  They are certified to ISO 4589 = 25 and are made from cross-linked polyolefin and modified polyolefin. Amphe-HST provides economical and effective insulation to protect all functional parts, components, harnesses and systems where it is used.

In addition to shrink tubing, the Amphe-HST line also includes molded parts for low to medium voltage breakouts, cable feed throughs and insulation marker sleeves and application equipment like heat guns and conveyor ovens.

Manufactured from cross-linked polyolefin and fluoropolymer materials, the majority of Amphenol’s shrinkable products have been tested and comply with UL/CSA, IEC, ASTM, MIL and ISO specifications. Amphe-HST can easily be used in electrical insulation, strain relief, environmental protection, splice sealing, mechanical protection, wire bundling and identification applications.
