Longwall shearer & Bretby handler
Type 241 / 275 screened cables are purpose-built for longwall shearer Bretby handlers.
Product
Elastomer-insulated, heavy-duty HD-85-PCP sheathed reeling, trailing and feeder cables for underground coal mines to AS/NZS 1802. Select the type by screen, earth, pilot and flexibility class across 1.1/1.1 kV to 11/11 kV.
Typical values for this cable type, based on AS/NZS 1802 — confirmed in the datasheet and quotation for your order.
Application fit
Australian/New Zealand standard AS/NZS 1802 elastomer-sheathed trailing and reeling cables (Types 209, 210, 240, 241, 275) for underground coal shearers and shuttle cars.
Type 241 / 275 screened cables are purpose-built for longwall shearer Bretby handlers.
Type 210 / 275 shuttle-car reeling cables withstand continuous spooling under tension.
Direct underground roadway and face trailing behind continuous miners, bolters and LHDs.
Gate-road flitting loops and DC/AC mobile face feeders.
Flexible trailing construction — for fixed roadway or shaft feeders use AS/NZS 1972.
