What is swa in the cable mean?

SWA stands for Steel-Wire Armored, referring to a type of electrical cable designed for durability and protection. It consists of conductors surrounded by a layer of steel wire armor, which provides mechanical strength and safeguards against physical damage. SWA cables are commonly used in outdoor installations and in environments where the cable may be exposed to harsh conditions. The armor also contributes to the cable's overall safety and reliability in electrical applications.
