The W-7B Socket Fitting (Bowl Head Fitting) is designed to connect the insulator string to the tower crossarm in overhead transmission lines. Its bowl-shaped head accommodates the ball pin of the insulator, allowing flexible angular movement while maintaining secure attachment. The fitting is made of high-strength malleable cast iron or forged steel, with all ferrous parts hot-dip galvanized for excellent corrosion resistance. Stainless steel cotter pins ensure reliable locking. The W-7B socket fitting offers easy installation and reliable load transfer under tension, making it an essential component for suspension and tension insulator assemblies. It ensures long-term mechanical stability and safety in outdoor power line applications.
