Our 25mm² 5 Core Steel Wire Armoured (SWA) Cable is a highly durable and reliable solution for mains electricity supply in low voltage installation systems. Constructed with XLPE insulation, robust Steel Wire Armour (SWA), and a protective PVC oversweath, this cable is designed to provide mechanical protection and withstand various environmental conditions. Engineered for a rated voltage of 0.6/1kV, it is suitable for both internal and external fixed wiring applications.
Applications
This 25mm² 5 Core SWA Armoured Cable is commonly used for electricity supply in low voltage systems across diverse environments:
- Underground Laying: Suitable for direct burial thanks to its robust steel wire armouring, which provides enhanced protection from external mechanical damage.
- Power Networks: Essential for general power distribution within low voltage installations.
- Incoming Mains Supply: Often used as an incoming mains cable for residential, commercial, and industrial properties.
- Indoor & Outdoor Installations: Versatile for use in buildings, industrial plants, and various external applications.
The XLPE insulation offers excellent resistance to various fluids and chemicals, has good heat stability, and is UV resistant, further enhancing the cable's longevity and reliability.
Standards Compliance
Our 25mm² 5 Core SWA Armoured Cables are manufactured and tested to comply with or exceed the requirements of the following international and British standards:
- BS 5467: Electric cables. Thermosetting insulated, armoured cables for voltages of 600/1000 V and 1900/3300 V.
- IEC/EN 60502-1: Power cables with extruded insulation and their accessories for rated voltages from 1kV (Um=1.2kV) up to 35kV (Um=40.5kV) - Part 1.
- IEC/EN 60228: Conductors of insulated cables.
- Flame Retardancy: Compliant with IEC/EN 60332-1-2 (single vertical insulated wire or cable).
Construction Details
The cable's layered construction ensures high performance, durability, and safety:
- Conductors: Plain circular, compacted or shaped stranded copper or aluminium conductor (depending on selection), conforming to IEC 60228 Class 2.
- Insulation: Cross-linked polyethylene (XLPE), designed for a 90°C rated temperature, offering superior electrical properties and high-temperature resistance.
- Colour Identification (5 Cores): Typically Red, Yellow, Blue, Black, Green.
- Assembly / Inner Sheath (Bedding): The five insulated conductors are laid-up together with non-hygroscopic fillers and the assembly is bedded with an extruded layer of PVC.
- Armour: Galvanized Steel Wire Armour (SWA) is applied helically over the bedding, providing robust protection against mechanical stress and impact.
- Sheath: An outer layer of Extruded PVC Type ST2 as per IEC 60502-1 or Type 9 as per BS 6346/5467.
