BS7835 Standard Cable

BS7835 Cable Description

BS 7835 is a British Standard that specifies requirements and test methods for thermoset insulated armoured cables, particularly for medium voltage applications

BS 7835 single core cables typically use aluminium wire armour (AWA) and multi core cables use steel wire armour (SWA)

BS 7835 cables are typically used in public buildings, industrial facilities and power networks
