CJT 80 Series

The CJT 80 series joints are trifurcating transition, heat shrink joints for splicing three conductor 15 kV and 25 kV jacketed or unjacketed paper and lead laminated dielectric cable (PILC or VCLC) to three each, single conductor XLP and EPR extruded dielectric, tape, wire shielded, bare or jacketed concentric neutral cables.

Features and Benefits

  • Fast, consistent installation means lower installed costs
  • No lead wiping required for positive oil stops
  • Installation environment: use of torch adds flexibility to cable preparation in any climate
  • Heat activated seals ensure maximum protection against moisture ingress
  • Reinforced wraparound sleeve with aluminum foil liner provides rugged protection and a moisture vapor barrier
  • Wide cable ranges reduce inventory
  • Pressure tested for continuous operation at 15 psig at 110°C
  • Slim profile allows installation in confined areas

Standards

  • IEEE 404-2000

Tests reports

CJT 80 series joint qualification is based on the testing of the 15 kV trifurcating transition joints where the oil stop was proven, and the dielectric tests in the 15 kV and 25 kV single conductor joint tests respectively, as tested to IEEE 404-2000 at an independent laboratory.

Test reports are available as follows:

  • CJT 1580 series: HVS031104
  • CJ 1580 series: HVS031103
  • CJ 2580 series: HVS040423

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(s) maximums are not exceeded.
  • For size transitions outside the listed range consult the factory.
