20kV Single Core SWA Armoured Cable IEC Standard for Industrial and Underground Power Transmission
20kV Single Core SWA Armoured Cable is a medium voltage XLPE insulated power cable designed for reliable electrical transmission in utility networks, substations, renewable energy projects, industrial facilities, and underground distribution systems. The cable combines excellent electrical performance with strong mechanical protection, making it suitable for demanding installation environments.
Manufactured according to IEC international standards, the cable is widely used in medium voltage power systems requiring stable current carrying capacity, long service life, and enhanced protection against external mechanical impact.
What Is 20kV Single Core SWA Armoured Cable?
A 20kV Single Core SWA Armoured Cable is a single conductor medium voltage power cable protected by galvanized steel wire armour (SWA). The cable is designed for fixed installations where high mechanical strength and reliable power transmission are required.
The cable structure typically includes:
Copper or aluminium conductor
XLPE insulation
Metallic screen
Bedding layer
Steel wire armour
Outer sheath
SWA protection helps the cable resist:
Mechanical damage
Compression force
Impact during installation
Underground environmental stress

Important Installation Note
For AC single core systems, non-magnetic armour such as AWA (Aluminium Wire Armour) is commonly recommended to reduce eddy current losses. However, SWA single core cables may still be used in specific DC systems, grounding systems, or project-specific applications depending on engineering requirements.
