The typical construction of an SWA Cable can be broken down as follows:
Conductor: consists of plain stranded copper (cables are classified to indicate the degree of
flexibility. Class 2 refers to rigid stranded copper conductors as stipulated by British Standard )
Insulation:Cross-connected polyethylene (XLPE) is utilized in various power cables since it has great
water obstruction and phenomenal electrical properties. Protection in cables guarantees that conveyors and
other metal substances don’t come into contact with one another.
Bedding: Polyvinyl chloride (PVC) bedding is utilized to give a defensive limit among inward and
external layers of the link.
Armour: Steel wire covering gives mechanical security, which implies the link can withstand higher
anxieties, be covered specifically and utilized in outside or underground activities. The armouring is
ordinarily associated with earth and can likewise be utilized as the circuit defensive conveyor (“earth wire”)
for the hardware provided by link.
Sheath: A dark PVC sheath holds all segments of the link together and gives extra insurance from outer
SWA Cable can be alluded to all the more by and large as Mains Cable, Armored Cable, Power Cable and Booklet
Armored Cable. The name Power Cable, in any case, applies to an extensive variety of links including 6381Y,
NYCY, NYY-J and 6491X Cable.
