CJ R10 Series

CJ R10 series joints are single core, 15 kV to 35 kV, heat shrink repair joints for bare and jacketed concentric neutral cable. They are designed to repair faulted cables or joints by replacing the damaged area with a longer make-up connection. The CJ 10J series joints use the same joint components as the CJ R10 joints but are supplied with a wraparound jacketing sleeve to seal from cable jacket to cable jacket on jacketed concentric neutral cables.

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


  • IEEE 404-2000

Test Reports

The CJ 10 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 R10J series joints with jackets.

Test reports are available as follows:

  • CJ 1510 series: HVSO20080
  • CJ 2510 series: HVSO20081 and HVSO 20083
  • CJ 3510 series: HVSO20082


  • 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 CJ R10 series joints are for bare concentric neutral cables. The CJ R10J series joints are for repairing jacketed concentric neutral cables. 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.
