rn

rn Type 11 0.64/1.1kV BS6708 Trailing Cable features an EPR rubber insulation which allows cable flexibility on site for frequent coiling and diverting to support the coal mining extraction process. 3M Scotchcast 82-F2 cable joints feature 2131 resin which is flexible, flame retardant and moisture sealing for damp working environments experienced in deep underground coal mines.

rn

rn 3M 82-F2 flexible cable joints allow trailing cable to maintain cable bend radius for handling, installation and reeling applications.

rn

rn 3M 82-F2 Cable Joints are suitable also for both indoor and outdoor installations : weather exposed, direct burial underground, submerged and cable reels.

rn Some Mining Cable Jointing Tips

rn
    rn
  • rn Cut out all kinks, twists and crushed spots - if several joints are located close together, remove them all and install a single cable joint to eliminate possible multiple weak spots
    • rn
  • rn Take care not to nick or cut the cable construction (conductor, insulation, shield)
    • rn
  • rn When preparing mine power feeder cable make sqaure, even cable cuts. Leave no loose threads or sharp points protuding as corona could be initiated within the cable joint
    • rn
  • rn Stagger connections (crimped or mechanical) on conductors to reduce bulkiness in the joint and prmote cable flexibility
    • rn

rn When The Going Gets Tough.....

rn

rn 3M Scotchcast resins are highly modified to resist degradation and contamination by acidic and alkaline dusts experienced in the global mining and quarrying industrial sectors such as coal, clay, china clay, chalk, gypsum and limestone. 

rn

rn Pictured : Mining & Quarrying Conveyors. Electrical plant, equipment and machinery in the mining industry is designed and manufactured to withstand harsh environmental conditions. Naturally, cables and cable accessories such as cable joints should be carefully specified to avoid downtime caused by installation of underspecified equipment.

rn

rn Global economic growth and infrastructure development depends heavily on mined and quarried natural resources such as minerals, metal ores and coal. Open-cut and underground mining operations require powerful electric machines and cabling to enable extraction. Electrical equipment and cable systems are routinely exposed to heavy dust pollution, high machinery vibration and G-forces. Large scale digging and excavation equipment for open-cut mines, such as electric power shovels and large scale conveyors, require trailing, level-wind cable reels. Drill and blast equipment used for hard rock and underground mining require rugged, compact cable management systems. Mobile power is also needed for shotcrete machines, blast-hole drills, ceiling bolters, and other underground equipment.
