Underground Mining<br />
Problem:<br />
These high voltage cables will arc <strong>and</strong> “ground out” when electric digging shovels pierce through the<br />
rubber protective jacket of the cable. These cables carries 1KV to 5KV of electricity. This rubber jacket<br />
acts as an insulator <strong>and</strong> must be M.S.H.A. approved <strong>and</strong> flame resistant.<br />
Solution:<br />
The complete repair area was roughened using a small belt s<strong>and</strong>er. Surface area was then chemically<br />
cleaned using Cleaner Blend 300. FL20 Primer was applied <strong>and</strong> allowed to cure or dry for 15 minutes. A<br />
polypropylene mold jacket was clamped into position surrounding the repair area. Injection funnels were<br />
placed into the injection ports on the polypropylene mold jacket. Cable Cast (8 minute pot life),was<br />
injected into the mold using <strong>Devcon</strong>’s Auto Mix Application System. Following a 16 hours functional<br />
cure, the mold jacket was removed. Cable Cast provided a long lasting,flame retardant, M.S.H.A.,<br />
abrasion resistant, cable jacket repair accepted in the underground mining industry.
