Trailing & towing
Built for trailing behind draglines, shovels, drills and pumps; Types 409 and 440 for long, abrasive runs.
Product
Elastomer-insulated, heavy-duty sheathed power cables for draglines, shovels, drills and pumps in open-cut and metalliferous mines. Choose the type by screen, earth and pilot design, then the voltage grade and size.
Typical values for this cable type, based on AS/NZS 2802 — confirmed in the datasheet and quotation for your order.
Application fit
All types power mobile plant. Pick the type for the machine's earth, pilot and screen design, then check the bending radius for the duty.
Built for trailing behind draglines, shovels, drills and pumps; Types 409 and 440 for long, abrasive runs.
Slow reeling (Types 441, 450, 451, 455); bending radius 12 × OD from 3.3 kV.
Ask engineeringDerate current on drums: 0.85 for one layer down to 0.35 for four layers.
Ask engineeringType 412 suits armoured feeder runs; other types are designed for mobile equipment in free air.
AS/NZS 1802 underground mining cableSheath rated for immersion and temporary water coverage, not for permanent submersion.
Ask engineeringFlexible unarmoured trailing construction — do not suspend in deep vertical mine shafts without support.
Use BS 6708 Type 20/21 ArmouredConstruction
Shown: Type 409 — three composite-screened phase cores around a central pilot. Other types differ in screen, earth, pilot and reinforcement (see Types in this range).
