This is a Brass Cable Gland (Type BW), typically used for armoured cables in indoor installations. It provides mechanical support and ensures earth continuity through the armouring. Made from high-grade brass, this gland ensures durability, corrosion resistance, and a secure grip on the cable. The BW type is suitable for dry, indoor environments and helps maintain a safe, tight seal where the cable enters electrical equipment or enclosures. Commonly used in power distribution, switchgear, and control panels.
