CJ 320 Series

Heat shrink medium voltage joints​

CJ 320 series joints are three core, 5 kV to 35 kV heat shrink joints for XLPE and EPR extruded dielectric, metal tape and wire shielded power cables. The CJ 320 series joints are supplied with three single core joints plus a railed wraparound sleeve with stainless steel channels to form a tube.

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 320 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 320 series joints with wraparound outer jackets.

Test reports are available as follows:

• CJ 3820 series: HVS020079
• CJ 31520 series: HVS020080
• CJ 32520 series: HVS020081 and HVS020083
• CJ 33520 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 the dimension ranges for the primary insulation and connector dimensions, and the jacket diameter.
• 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 31522P.
