Busbar Insulation Tube Suppliers

Applications:
Heavy wall HB3 has reliable insulation protection. It can provide the insulation and anti-flashover protection for busbars up to 36kV. 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:
  • Operating temperature: -45˚C~105˚C
  • Minimum shrink temperature: 100˚C
  • Full recovery temperature: Above 135˚C
Color:

red

Standard color: red (Busbar width will vary depending on the design of the manufacturer. The recommended size is for reference only.)
