Basic Requirements For Power Cable Connection Fittings

Basic requirements: aerial electrical fitting are generally made of cast steel and malleable cast iron. Requirements power line hardware should have sufficient mechanical strength, and the part overhead line fittings that connects the conductor should have good electrical properties. distribution line hardware During the manufacturing process, there should be no burrs, flash, sand holes, bubbles, cracks, deformations, the surface should be smooth, and the galvanized layer should be uniform. The matching overhead line connectors should be suitable in specifications, without missing parts, and without rust. The screws and nuts should match well, the contact surface between the clamp hull pressure plate and the wire should be smooth, and the manufacturing quality and size should meet national standards.
