Detail
Size specification
  • Name: S1(n)-10 Halogen Free Bus Bar Insulation Heat Shrink Tube
  • Colour: Standard color : Red
  • Temperature: Operating temperature: -40~105 ℃;Shrink temperature: 125 ℃.
    • Icon:
    • Features:
         Medium wall cross-linked polyolefin ;      Bus bar insulation and protection;
        Reduces bus bar clearance requirement ;      Shrink ratio: 2.5:1;
        Halogen free, RoHS compliant ;      Voltage class: 6~24KV;
         Protects against short circuit and electrical leakage caused by small animals.  
       Typical application:
         Suitable for insulation and protection of bus bar against accidental flashover up to 24 KV;
         Ideal for using in switchgears cabinets where space is limited and air spacing between busbars need to be kept at minimal.
      Dimensions:
