A 4 Core SWA (Steel Wire Armoured) Cable is an electrical cable that consists of four conductors surrounded by layers of insulation, steel wire armour, and an outer sheath. The four cores or conductors within the cable are typically color-coded for easy identification. The steel wire armour provides mechanical protection, making the cable suitable for use in harsh environments, such as underground installations or areas prone to physical damage. SWA cables are commonly used for power distribution, both indoors and outdoors, where durability and protection are required.
Conductors: The cable consists of four conductors, which are typically made of copper or aluminum. Each conductor carries an electrical current and is responsible for transmitting power or signals.
Insulation: Each conductor is individually insulated with a layer of material, such as PVC (Polyvinyl Chloride), XLPE (Cross-Linked Polyethylene), or EPR (Ethylene Propylene Rubber). The insulation provides electrical insulation and prevents leakage or short circuits.
Steel Wire Armour: The insulated conductors are surrounded by a layer of steel wires, which provides mechanical protection. The steel wire armour enhances the cable's resistance to impact, crushing, and external stresses.
Outer Sheath: The entire cable is covered by an outer sheath, typically made of PVC or LSZH (Low Smoke Zero Halogen) material. The outer sheath provides an additional layer of protection against moisture, chemicals, and environmental factors.
Based on the variation in insulating materials used, the 4 Core SWA Cable can be categorized into PVC SWA cable, XLPE SWA cable, and XLPE SWA LSF cable. The XLPE SWA cable finds application as medium voltage (MV) and low voltage (LV) armour cable, with a maximum operating temperature of 90 degrees Celsius. On the other hand, the PVC SWA cable is used exclusively for LV armour cable, with a maximum operating temperature of 70 degrees Celsius. The XLPE SWA LSF cable employs low-smoke and halogen-free XLPE insulation for its insulating material.

Power Cables: Copper vs. Aluminum Conductors
Conductors consist of materials that conduct electric current, or the flow of electrons. Nonmagnetic metals are typically considered to be ideal conductors of electricity. The wire and cable industry uses a variety of metal conductors, but the two most common are copper and aluminum. Conductors have different properties such as conductivity, tensile strength, weight and environmental exposure.
