Detailed Description
Reel Cable for Scraper-Type Machines — Smaller, Smarter, Same Reliability
The bucket wheel stacker reclaimer reel cable carries 3.6/6 kV at 400 mm² over 500 m — it is a heavy-industry main power feeder. The scraper-type stacker reclaimer reel cable carries 0.6/1 kV at 35–95 mm² over 50–200 m — it is a medium-power, medium-travel cable for the workhorse machines of smaller bulk handling operations.
The engineering is the same — steel wire tensile core, EPR insulation, CR or PUR jacket — but scaled to the actual machine requirements. Over-specifying a bucket-wheel-grade cable for a scraper reclaimer adds cost without adding value.

Coal Yard — The Most Common Application
Coal-fired power plants typically use scraper reclaimers, not bucket wheels, for fuel yard management. The coal yard cable environment is uniquely demanding:
- Coal dust is conductive: Carbon-based dust can create tracking paths across insulation surfaces if moisture is present. The cable jacket must maintain a clean, non-tracking surface
- Coal dust is potentially explosive: MSHA certification (CR jacket) verifies flame safety and anti-static properties
- Spontaneous combustion risk: Coal stockpiles can self-heat. The cable must not contribute fuel or toxic gas if exposed to elevated ambient temperatures
Cement Plant — Corrosive Dust, Not Abrasive Dust
Cement raw material (limestone, clay) dust is chemically different from coal dust:
- Alkaline (pH 10–12 when wet): Limestone dust + water = calcium hydroxide — attacks PVC and standard rubber
- Highly hygroscopic: Absorbs moisture from the air, forming a paste on cable surfaces
- Abrasive when dry: Acts as a fine grinding compound between cable turns on the drum
Why Choose Yichi Cable Reclaimer Reel?
- Right-sized engineering: 15 kN tensile, not 80 kN. 35 mm², not 400 mm². The cable matches the machine
- Material-matched jacket: CR for coal (MSHA + conductivity), PUR for cement/fertilizer (chemical resistance)
- Control + fiber integration: One reel, one cable, all connectivity
- Application review: Send us your machine type, travel distance, and material handled — we specify the correct jacket and tensile reinforcement
