Heatshrink Cable Glands

For The Support & Sealing Of Unarmoured Cables

It is imperative that LV MV HV cables terminated into railway signalling equipment should be protected against the risk of accidental damage caused by external forces pulling at the heat shrink cable termination connections and ingress of moisture which may result in equipment failure operating at Low, Medium or High Voltage.

The HCS series of heat shrink cable glands were developed to provide a cost effective method of ensuring a secure cable support and weatherproof seal on all types of non-armoured railway signalling cables – the cable glands are not suitable for steel wire armoured (SWA) or aluminium wire armoured (AWA) cables.

The high shrink ratio heatshrinkable collar enables suitability for a range of cable diameters shown in the below table. The heat shrink glands are manufactured in accordance with MIL-1-81765/1 and MIL-1-23053/15 specifications and provide a flame retarded adhesive lined body along with a male threaded bush to enable fixture to the cable gland plate of the electrical equipment, cable box or enclosures.

A range of cable glands are available complete with brass threaded adaptor, locknut and fibre washers to suit all types of rail signalling and switching equipment. The majority of cable glands with adaptors are intended to be clearance fit enabling them to be re-used upon servicing of electrical equipment.

Below is the Heat Shrink Cable Entry Sealing Glands application table.

The equipment application listed has been established with the cooperation of the NRS (Crewe) Technical Section.

Rail equipment cable entry apertures may vary depending on the equipment age, therefor it is highly recommended that this is taken into account when selecting a suitable heat shrink cable gland.
