4 core 150 mm² SWA armoured cable, generally abbreviated as SWA, is a hard-wearing power cable created for the supply of mains electricity. It is one of a number of armoured electrical cables– which involve low voltage Cable and medium voltage Cable– and is found in underground systems, power networks and cable ducting.
The common structure of an 4 core 150 mm² SWA armoured cable can be broken down as follows:
Conductor: includes plain stranded copper (cables are categorized to suggest the degree of flexibility. Class 2 describes stiff stranded copper conductors as stipulated by British Standard BS EN 60228:2005).
Insulation: Cross-linked polyethylene (XLPE) is used in a variety of power cables because it has good water resistance and excellent electrical properties. Insulation in cables guarantees that conductors and other metal substances do not enter into contact with each other.
Bedding: Polyvinyl chloride (PVC) bedding is used to supply a defensive border between inner and outer layers of the cable.
Armour: Steel wire armour provides mechanical protection, which implies the cable can stand up to higher tensions, be buried directly and used in external or underground projects.
The armouring is normally connected to earth and can sometimes be used as the circuit protective conductor (” earth wire”) for the equipment supplied by cable.
Sheath: a black PVC sheath holds all elements of the cable together and provides additional protection from external stresses.
4 core 150 mm² SWA armoured cable can be described more typically as mains cable, armoured cable, power cable and brochure armoured cable. The name power cable, however, applies to a wide variety of cables including 6381Y, NYCY, NYY-J and 6491X Cable.
Due to above 4 core 150 mm² SWA armoured cable structure,which has many advantages,as follow:
4 core 150 mm² SWA armoured cable has added protective armour can resist stronger mechanical forces and prevent damage from exterior forces that helps protect the cable core. This is essential in position where there could be unintentional harm to the cable due to mechanical tension or effect.
To put it in context, generally, armoured cables would be used when you require the cable to be buried directly underground for outdoor setup or in tubes. There may be instances where the ground is opened up again, and in the process, a shovel or mechanical excavator may hit the buried cable by accident. In this case, the armour would help protect the cable conductor core from being revealed easily and prevent electric shocks and disruptions in power distribution.

The armoured electrical cable’s outer layer has a tough structure that effectively shields the conductor from outside damage. In harsh environments, it is frequently used as a form of burial. It is resistant to corrosion dued to acid rain and animal bites and has high security efficiency, stability, and dependability.
Cross-linked cables use cross-linked polythene for the outer insulating layer of the cable conductor, whereas armouring describes wrapping the outer protective level of the cable with steel tape or steel wire to safeguard it from issue by external mechanical forces. It is possible to use an armoured XLPE cable, which has an armoured outer layer and is insulated with a cross-linked material.
Due to above 4 core 150 mm² SWA armoured cable Feature,which has many applications,as follow:
Utilized in transformer stations, switching blocks, in electric power plants and industrial plants. 4 core 150 mm² SWA armoured cable for static application in ground, within and outside facilities, outdoor, in cable canals, in water, in conditions where cables are not exposed to heavier mechanical tension and tensile strain.
To prevent the effects of external impact, the adhering semi-conductive layer extruded between conductor and insulation, together with concentric copper conductor, safeguards constraint of
electric area and resistance to partial discharges.
Because of its very low element of dielectric decrease, which remains continuous over its whole operating lifetime, and owing to excellent insulation property of XLPE-material, firmly longitudinally spliced with inner and external screen of semi-conductive material (extruded in one process), the cable has a high running dependability.
When it concerns armored cables, it is vital to consider factors for example, cable size, conductor material, type of insulation, and certification requirements. As professionals in this field, we are regularly updated with the latest industry standards and policies to ensure compliance and optimum performance.
