- Product Details
Steel Wire Armoured Cable (Swa Cable) is a high-strength electrical cable designed for use in harsh environments, where mechanical protection, corrosion protection and long-term durability are required. Its use of galvanized steel wire armour and multi-layer insulation material makes it the preferred electrical wire for underground laying, direct burial installation and outdoor exposure in industrial or construction. Steel wire armored cables are available in sizes 1.5mm²-300mm². Some of the common ones are 6mm armored cables, 16mm armored cables and 70mm armored cables.
Key Advantages
- Spiral-wound galvanized steel wire provides 360° protection against external impacts, crushing, rodent bites and construction damage. Reliable performance over decades with minimal maintenance costs.
- It provides excellent fire resistance and low smoke emissions. Prioritizes the safety of people and property in high-risk or densely populated environments.
- Steel wire armored cables applications meet a variety of installation conditions, providing consistent power transmission across different climates and demanding applications.

FAQ
Can SWA cable be buried directly in the ground?
Yes. The steel wire armor provides sufficient mechanical protection against impact (e.g., from spades), allowing it to be buried directly without a conduit. It should typically be buried at a depth of 450mm to 600mm with marker tape above it.
What is the minimum bending radius of SWA cable?
Generally, it is 8 times the overall diameter of the cable. Bending the cable tighter than this can damage the internal insulation or cause the steel wires to splay
Can you bend a SWA cable?
Yes, but strictly limited. SWA is rigid and designed for fixed installations, not repeated flexing.
