Physical & electrical characteristics
11 kV Single Point Suspension Cable
22 kV Single Point Suspension Cable
Single Point Suspension cables, also known as Borehole cables, play a vital role in both underground coal and metalliferous mining operations. Designed to be self-supporting when lowered vertically down shafts or boreholes, these cables transfer the mechanical strain from the suspension components — not the electrical conductors — ensuring durability and reliability. Featuring double armour construction engineered to resist torsional forces, SPS cables can be customized to include earth cores and fibre optic cables as required. Commonly applied in extensive overhead networks across mining sites, they provide power supply to remote working areas with typical voltages of 6.35/11 kV and 12.7/22 kV, conforming to AS/NZS 1972 and AS/NZS 1429.1 standards.
Product Features
Self-Supporting Design: Engineered to bear mechanical suspension strain through built-in components, protecting electrical conductors.
Double Armour Construction: Provides high resistance to torsional forces during suspension in vertical shafts or boreholes.
Versatile Core Options: Can incorporate earth cores and fibre optic cables as per project requirements.
Compliance and Safety: Meets Australian standards for underground coal and metalliferous mining environments (AS/NZS 1972 and AS/NZS 1429.1).
Durable Materials: XLPE insulation, semiconducting screens, and galvanised steel armour ensure high mechanical, chemical, and environmental resistance.
Application Areas
Primarily used in underground coal and metalliferous mines as suspension cables for overhead power networks, providing power to remote working areas via boreholes drilled at strategic points in the mine.
Quality Certifications
AS/NZS 1972
AS/NZS 1429.1
Installation and Maintenance
Designed to be suspended vertically from surface installations down mine shafts or boreholes. Proper installation ensures mechanical strain is absorbed by the cable armour and suspension system. Periodic checks recommended to maintain cable integrity and ensure optimal performance.
Customization Services
Options available to include earth cores, fibre optic cables, and tailored cable lengths according to specific project needs.
