Insulated Jumper Sets

Chance insulated jumper clamps are used for bypassing work areas where equipment is under repair, the line is being upgraded, and for making temporary or other emergency repairs.

Pre-assembled for popular distribution-system voltages, ten sets offer a choice of cable sizes. Based on cable size selected, continuous-current ratings for sets range from 200 to 400 amperes. All sets include cable listed below.

15 kV Jumper Cable
Size, AWG Continuous Current Rating, Amperes Reference Cat. No.
#2 200 S10043
1/0 260 S10044
2/0 300 S10045
4/0 400 S10046
25 kV Jumper Cable
Size, AWG Continuous Current Rating, Amperes Reference Cat. No.
1/0 260 S11272
2/0 300 S11273
35 kV Jumper Cable
Size, AWG Continuous Current Rating, Amperes Reference Cat. No.
1/0 260 S11274

Ampacity ratings are based on 90°C conductor temperature at 40°C ambient.

AWG size and voltage rating are embossed at 4-ft. intervals on EPR (ethylene-propylene) insulated jacket.

Insulation and conductor screen meet and exceed ICEANEMA standard S-68-516. Extra-flexible conductors are alloy-coated copper-stranded rope per ASTM B-189 or B-33.

Jumper clamps feature "floatingwasher" design and high-impact polyethylene handles with wide handguard flange.

  • Small 15kV clamp has 55/8" handle below handguard.
  • Large 15 kV and 25kV clamps each has 71/2" handle below handguard
  • 35kV clamp has 83/8" handle below handguard.

NOTE: Adequate rubber gloves must be worn when installing or removing jumper clamps.

All Chance® Insulated Jumpers meet ASTM F 2321 Standard Specification.
