Rain sheds are used as creepage extenders on medium voltage cable termination and insulators in outdoor applications. The recommended number of sheds to be used varies according to the voltage rating of the cable.

Features and Benefits

  • Non-tracking
  • UV stabilised
  • Flame retardant
  • Rubber based red sealent seals the shed to the cable
  • Exceptional electrical and weathering properties
  • Suitable for outdoor & indoor terminations
  • Shrink ratio: 3:1
  • Continuous operating temperature: -40°C to 100°C
  • Shrink temperature: 125°C min.


  • HD 629.1 S2
  • IEC 60502-4
  • IEC 60055-1

Typical Applications

Creepage extension on medium voltage terminations up to 36kV, improved tracking resistance in harsh environments, suitable for the complete range of electrical cables with XPLE or PILC insulation


  • Industrial
  • Utility


Select a dimension which will shrink snugly over the application to be covered. If recovery is restricted the resultant wall thickness will be less than specified.

  • Select options:
  • Color: Red-brown (RD-BN)
  • Please specify the product name, order number and options you require
  • Example: CRSA 37/16, red-brown

Please contact your Customer Service Representative for information on custom colors, sizes, lengths and material data sheet.
