Armored cables have specific features that make them suitable for various applications.
Key Specifications:
- Conductor Material: Copper or aluminum, with copper being more conductive.
- Insulation Material: Cross-linked polyethylene (XLPE) or polyvinyl chloride (PVC), with XLPE offering higher current ratings and longer service life.
- Armour Material: Steel wire armour (SWA), steel tape armour (STA), or aluminum wire armour (AWA), providing mechanical protection and tensile strength.
- Sheath Material: PVC or low smoke zero halogen (LSZH), offering protection from external stresses and environmental factors.
- Voltage Rating: Typically 600/1000V, 6.35/11kV, 8.7/15kV, and 19/33kV, depending on the application.
- Temperature Rating: Up to 80-250C, depending on the insulation material and application.
- Bending Radius: Typically 6-8 times the overall diameter, depending on the specific type ² ³.
Types of Armored Cables:
- Steel Wire Armoured (SWA) Cable: Suitable for power distribution, outdoor use, and underground installations.
- Steel Tape Armoured (STA) Cable: Used for buried laying and can withstand external mechanical forces.
- Aluminum Wire Armoured (AWA) Cable: Used in single-core cables to avoid eddy currents and suitable for power systems and substations.
Applications:
- Industrial Settings: Factories, warehouses, and manufacturing plants.
- Outdoor Installations: Construction sites, parks, and exposed areas.
- Underground Systems: Buried cables, tunnels, and cable ducting.
- Power Distribution: Power networks, substations, and electrical distribution systems
