Single Wall Heat Shrink Tubing, WMPG
Model: WMPG
Heat shrinkable busbar insulation tubing
WMPG busbar insulation tubing is single wall heat shrink tubing made from cross-linked polyolefin. It is perfect for copper or aluminum busbars in switchgear and substation, providing insulation and protection against short circuit and electrical leakage. Various color options are available for busbar color distinction.
Features
- Shrink ratio: 2:1
- Made from cross-linked polyolefin
- Insulation and protection of busbars in switchgear and substation
- RoHS compliant
- Shrink temperature: start at 70℃, and fully recovered at 125℃
- Color: yellow, red, green, blue, black
- Busbar insulation
- Protection against short circuit and electrical leakage caused by small animals
- Reduction of busbar clearance
- Busbar color distinction
