Industry: Underground Mining
Associated Products: Jacket Repair Kit, Cable Cast FR

Problem:
These high voltage cables will arc and "ground out" when electric digging shovels pierce through the rubber protective jacket of the cable. These cables carries 1KV to 5KV of electricity. This rubber jacket acts as an insulator and must be M.S.H.A. approved and flame resistant.

Solution:
The complete repair area was roughened using a small belt sander. Surface area was then chemically cleaned using Cleaner Blend 300. FL20 Primer was applied and allowed to cure or dry for 15 minutes. A polypropylene mold jacket was clamped into position surrounding the repair area. Injection funnels were placed into the injection ports on the polypropylene mold jacket. Cable Cast (8 minute pot life),was injected into the mold using Devcon's Auto Mix Application System. Following a 16 hours functional cure, the mold jacket was removed. Cable Cast provided a long lasting,flame retardant, M.S.H.A., abrasion resistant, cable jacket repair accepted in the underground mining industry.
