The 3 core steel wire armored cables manufactured at the ZMS factory are commonly used in the electrical industry and strictly conform to specific British Cable Manufacturing and Testing Standards.

• Used as an electrical power supply and auxiliary control for equipment, 3-core armored power cable transmits mains power to a residential building or commercial facility, so it can also be referred to as a 3-core power cable, and is abrasion-resistant for use in applications where the cable may be damaged or exposed to UV radiation.
• Traditional 3-core steel wire armored (SWA) cables are ideal for exterior electrical applications. Since such applications must often withstand natural forces, SWA outdoor 3-core cables add an extra layer of sleeving (usually wire mesh) to provide greater mechanical protection to the inner core of the cable.
