CJ 3A20 Series​

​Heat shrink medium voltage joints

CJ 3A20 series joints are three core armored, 5 kV to 35 kV heat shrink joints for XLPE and EPR extruded dielectric, metal tape and wire shielded power cables. The CJ 3A20 series joints are supplied with three single core joints, a galvanized steel wraparound armoring system and a railed wraparound sleeve with stainless steel channels to form the outer jacket.

Features and Benefits

  • Fast, consistent installation means lower installed costs
  • Installation environment: use of torch adds flexibility to cable preparation in any climate
  • Heat activated seal ensures maximum protection against moisture ingress
  • Custom tailored with options to your exacting needs
  • Lightweight construction requires no additional support
  • Wide cable ranges for reduced inventory requirements
  • Tough abrasion resistant outer covering protects against damage from improper backfill
  • Slim profile allows installation in confined areas

Standards

  • IEEE 404-2000

Tests Reports

The CJ 3A20 series joints were design tested to IEEE 404- 2000 at an independent laboratory as single core unjacketed joints. This represents the worst case condition as the joints submerged under water were not afforded the added protection of the CJ 3A20 series joints with wraparound outer jackets.

Test reports are available as follows:

  • CJ 3A820 series: HVS020079
  • CJ 3A1520 series: HVS020080
  • CJ 3A2520 series: HVS020081 and HVS020083
  • CJ 3A3520 series: HVS020082

Ordering

  • Find the cables voltage class and conductor size(s) to be spliced. Select the kit order number that covers the conductor size range.
  • Confirm the dimensional data particularly when the conductor size is at the extremes of the range. The overlap in size ranges allows for size transitions when splicing different cable sizes. The determining factors for selection are that the minimum and maximum dimensions for the primary insulation and connector dimensions are met and that the jacket diameter maximum is not exceeded.
  • A cable preparation/cleaning kit can be included with the kit by adding the suffix to the end of the order number. FOR EXAMPLE: CJ 3A1522P.
