Heat shrink Bus bar tubing ,Thin wall
2024/7/25 viewers
- BrandDEEM
- TypeDB-BL
Introduction
ApplicationsSuitable for insulation and protection of bus bar against accidental flashover up to 1
KV. Ideal for using in switchgears cabinets where space is limited and air spacing
between bus bars need to be minimized.
Features
Flame retardant thin wall cross-linked polyolefin
Bus bar insulation and protection
Reduces bus bar clearance requirement
Halogen free, RoHS compliant
Protects against short circuit and electrical leakage caused by small animals.
Various
Operating temperature: -40 to +105 °C. Minimum shrink temperature: 125 °C. Voltage
class: 1KV
Standard color: Black
