DUWAI HB3 - Busbar Insulating Heat Shrink Tubing (Withstand Voltage Up To 35kV)
APPLICATIONS
Heavy wall HB3 has reliable insulation protection. It can provide insulation and anti-flashover protection for busbars up to 35kV. The cross-linked polyolefin material has UV resistance and flame retardant properties, and can provide long-term insulation and withstand voltage protection for busbars in harsh high temperature and chemical environments.
OPERATING TEMPERATURE RANGE
- Continuous operating temperature: -45℃ ~ 105℃
- Minimum shrink temperature: 100℃
- Full recovery temperature: Above 135˚C
COLOR
Standard color: red, (Busbar width will vary depending on the design of the manufacturer. The recommended size is for reference only.)
- Shrink ratio: 2.5:1
- Flexibility and corrosion resistance
- Excellent chemical resistance and insulation performance
The 35KV high-voltage insulated busbar heat shrinkable tube is made of environmentally friendly polyolefin heat shrinkable material cross-linked by high-energy electron beam bombardment. It has excellent flame retardancy, insulation and thermal stability, and can provide high insulation strength and electrical resistance. Carbon trace performance. It limits environmentally harmful substances such as PBB, PBBD, PBBE and heavy metals. It does not produce toxic gases and harmful substances when burned. It is suitable for anti-corrosion and insulation protection of busbars and electrical equipment. It has passed the certification of Wuhan High School and West High School. Products are widely used in the power industry, communications, automobiles, ships, aircraft manufacturing and other fields, and are often used for insulation protection of busbars in high-voltage environments such as substations.
