The bonding clamp is used to ground OPGW to the tower by attaching to the tower grounding wire. Specific requirements vary from one utility to another. The product is an aluminum extruded parallel groove clamp. Application ranges from aerial, uct to buried. umber of over-head line applications for the transmission of information. We have been developing fittings for fib data transmission in such cables takes place via modulated. electric aerial ground wire and fiber communication. It is constituted of AS wire, AA wire and stainless steel tube op-unit. Parallel groove clamp (PG Clamp) is designed to connect two conductors in parallel and especially used to hold transmission conductors in. The engineering department compiles the OPGW cable engineering plan (or operation guide including spanning chart and schedule) according to the line, length, and pre-reserved joint position, checks the relevant data,masters the composition of the entire communication system and the detailed.
