FAQs
Frequently Asked Questions
What is the Heat Shrink Shroud used for?
It is used for:
- Sealing the cable entry point on cable glands
- Strain relief and moisture, dust and water protection at gland entries
How is it installed?
Clean and degrease the surface, position the part, then shrink it with a gas torch or a hot-air gun: keep the heat moving round it with a smooth, brushing motion so it recovers evenly without scorching. Start at one end and work steadily along to the other.
Which standards and test methods are quoted for it?
These, with the values in the Technical Specification on this page:
- ASTM D638
- ASTM D792
- ASTM D2671
- ASTM D2240
- ASTM D570
- ESI 09-11
- ASTM D149
- ASTM D257
- ASTM D150
- IEC 216
