AG’s range of Heat Shrinkable Cable End Caps are used for sealing the ends of cables and ropes to protect from moisture, weathering and fraying ends.
Manufactured from highly durable cross-linked polyolefins, each end cap is lined with a thick layer of hot-melt adhesive that flows when heated, bonding the cap to the cable and forming the seal.
Each end cap is UV stabilized and exhibit excellent resistance to chemicals and other media. They also provide good electrical insulation properties with a dielectric strength >12kV/mm.
What applications are they used for?
Put simply, cable end caps are used to protect and seal the ends of cables. They will generally be used during the construction of plants, factories and other buildings or during the manufacture of machinery to protect electrical cable ends while they are held in storage or while being laid to shield from weathering influences, corrosion of the core wire or other direct damage and soiling.
They can be used on a whole range of cables. From PVC coated cables to silicone coated cables, electrical cords, data leads and fibre optic cables.
Heat Shrinkable End Caps can also be applied to the ends of ropes to prevent them from fraying.
How are Cable End Caps applied?
The end caps must first be exposed to a significant heat source. A heat gun is recommended if you have one, so that you can apply the correct amount of heat without melting the caps. Start at the closed end and move towards the open end once shrinking. You will find that once exposed to the heat, the caps will quickly shrink and the glue will run, filling the gaps and creating the air and water-tight seal. You may see a small bit of glue come from the end, this indicates a good seal.
What sizes are available and which one’s right for me?
AG carries a complete range of end cap sizes that will seal and protect cables all the way from 2mm Ø through to 158mm Ø. The end caps have about a 3:1 shrink ratio. So as long as your cable is not smaller than 1/3 of the diameter listed below, then the cap will work. They do not need to shrink all the way to 1/3 of the size to form a seal, as long as they shrink a little bit, the glue will create the seal. For example it would be fine to use either a 12mm or 14mm end cap for a 10mm cable.
Here is the complete list of sizes available:
- 8mm Ø
- 12mm Ø
- 14mm Ø
- 25mm Ø
- 40mm Ø
- 55mm Ø
- 75mm Ø
- 100mm Ø
- 130mm Ø
- 158mm Ø
