Physical & electrical characteristics
This 11/11 kV paper insulated, paper belted, lead sheathed, galvanised steel wire (GSW) armoured cable is designed according to AS1026 and AS/NZS 1972 standards. It is widely used as a high voltage feeder cable in power reticulation systems throughout mines and industrial networks. Suitable as a primary power supply cable for systems requiring high earth fault current capacity. Note that the 12.7/22 kV XLPE cable variant offers alternative advantages such as higher temperature rating allowing cable size reduction, with associated cost, size, and weight savings.
Product Features
High Voltage Capability: Designed for 11/11 kV power reticulation systems in mining and industrial environments.
Robust Construction: Paper insulated and belted cores with lead alloy inner sheath and galvanised steel wire armour provide mechanical strength and excellent electrical performance.
Durable Outer Layer: PVC outer sheath in red for environmental protection and identification.
High Earth Fault Capacity: Suitable for systems requiring high earth fault current capabilities.
Wide Installation Options: Suitable for installation in free air, ducts, or direct buried applications.
Traditional Design: While effective, the cable is rigid and has no fire performance rating compared to modern XLPE alternatives.
Application Areas
Used extensively across mining power reticulation networks as primary power supply cables, especially where high earth fault values are expected.
