The special purpose of power fittings is strictly required by national standards. Power fittings are metal components used to connect transmission line towers, conductors, lightning rods, and insulators, or to protect conductors, lightning rods, insulators, and other components.

Electric power fittings are generally made of cast steel and malleable cast iron. It is required that the circuit fittings should have sufficient mechanical strength and have good electrical performance for the parts of the fittings connecting the conductive body. During the manufacturing process of circuit fittings, there should be no burrs, burrs, sand holes, bubbles, cracks or deformations, the surface should be smooth and clean, and the galvanized layer should be uniform. The supporting hardware should be of suitable specifications, without missing parts, and without rust. The screws and nuts should be well matched, and the contact surface between the wire clamp and the wire should be smooth. The manufacturing quality and size should comply with national standards and specifications.
