railway power cable

The AS/NZS 1802 Type 241 3x35mm² 1.1kV mining cable has a total weight of approximately 2,980 kilograms per kilometer, with copper content contributing roughly 1,500 kilograms per kilometer of that total. This cable has a 43.1 millimeter nominal outer diameter (tolerance range 41.5–44.5mm), carries an ampacity rating of 147 amperes in free air at 90°C conductor temperature, and is constructed from three 35mm² power conductors, three 16mm² interstitial grounding conductors, and one 16mm² central extensible pilot conductor (the latter typically used for remote control signaling in mining equipment). The cable is built to AS/NZS 1802 standard using EPR (ethylene propylene rubber) insulation and heavy-duty HD-85-PCP (polychloroprene) outer sheath, making it ideally suited for the extreme mechanical and thermal stresses of underground coal mining trailing cable applications—continuous miners, pump power supplies, and general mining equipment feeder systems. However, this specification applies exclusively to authentic AS/NZS 1802 Type 241 cables. Understanding this distinction is critical because many engineers and procurement teams encounter confusion when they search for “Olex Type 241” or “Versolex Type 241 equivalent,” terms that conflate two fundamentally different product families with completely different material systems, standards, and field applications.
