70mm 4 Core Heavy Duty SWA XLPE PVC Armoured Cable

Professional-Grade Power Transmission for Demanding Environments

This 70mm 4-core SWA XLPE PVC armoured cable is engineered for high-current power distribution where durability and reliability are non-negotiable. With four conductors each having a cross-sectional area of 70 square millimeters, this cable supports higher current loads and complex circuit configurations compared to single or three-core alternatives. The 4-core configuration makes this cable perfectly suited for three-phase AC power distribution, commonly used in industrial and commercial installations, and supports currents up to approximately 220–260A depending on installation method and ambient temperature.

Superior Material Construction for Long Service Life

Stranded plain annealed copper conductors deliver flexibility and low resistance, ensuring excellent electrical efficiency over long-distance runs. Modern XLPE insulation offers superior short-circuit withstand, lower dielectric losses, and higher temperature tolerance compared with traditional PVC, allowing maximum operating temperatures of 90°C. Galvanised steel wires are applied helically in a single layer with wire diameter typically 0.9 mm to 3.15 mm scaled with cable size to ensure near-100% coverage and high impact resistance.

Mechanical Protection That Prevents Costly Failures

The SWA armour provides excellent mechanical protection, making the cable highly resistant to physical damage, particularly beneficial for underground installations or environments where the cable might be exposed to mechanical stress or impact, and capable of withstanding external forces such as crushing and pulling during installation. The PVC sheath provides excellent resistance to chemicals, oils, and moisture, making the cable suitable for harsh industrial environments, and protects against corrosion, extending the cable's lifespan even in moist or corrosive environments.

Versatile Installation Options for Any Application

This cable is suitable for fixed installations for use indoor, outdoor or for direct burial. The steel wire armoured cable is the accepted standard for underground installations, designed for use in mains supply electricity. Common applications include large outbuildings such as on farms, industrial conveyor systems, high powered machinery, mains power supply to units and warehouses, three phase and earth circuits, and large three phase motors.

Performance Specifications Built to Standards

This cable is rated for 90°C maximum conductor operating temperature and 600/1000V voltage rating. These cables comply with BS 5467 (UK) for XLPE-insulated, PVC-bedded and sheathed armoured cables, and IEC 60502-1 for extruded solid dielectric cables rated up to 1 kV, ensuring regulatory compliance and predictable performance across diverse industrial applications.

Long-Term Cost Efficiency Through Durability

Due to its robust construction and resistance to environmental factors, the XLPE/PVC/SWA/PVC cable tends to have a longer service life, reducing the need for frequent replacements and maintenance and providing a cost-effective solution over time. Whether routing power to remote facilities, feeding heavy industrial equipment, or managing three-phase distribution in manufacturing environments, this cable delivers the mechanical protection and electrical performance required for mission-critical installations.
