Description

technical field

[0001] The invention relates to the technical field of electrical fittings, in particular to a special fitting for melting ice from ground wires. Background technique

[0002] Optical cable parallel fittings are used to melt ice for ground wires of overhead transmission lines. They have the advantages of strong flow capacity, light weight, portability, and flexible disassembly. Optical cable parallel fittings are used to break the connection between optical cables to form a closed loop.

[0003] The traditional parallel wiring device for melting ice uses ordinary parallel trench clamps. The body and the gland are processed by profile cutting, and the bolts are prevented from loosening by using traditional spring washers. When the ice is melted and passed through a large current, it is easy to loosen due to the difference in thermal expansion coefficient of the material, thereby generating more heat. Ordinary parallel trench clamps have a small current flow c...
