Preferably, described support is ∏ shape support.
Preferably, described lightning arrester is metal oxide arrester.
Preferably, described wire is flexible conductor.
Preferably, described flexible conductor is copper cash or tubular bus.
Preferably, described wire clamp is device clamp and/or T-shape cable clamp.
Preferably, described fastening clip for cable comprises "Ji" type clamp and bolt, and the "Ji" type clamp blocks cable outdoor terminal, and is bolted on support.
Preferably, also be provided with the rubber blanket liner between "Ji" type clamp and cable outdoor terminal.
Preferably, on bolt also cover have and guarantee that when cable outdoor terminal expands with heat and contract with cold fastening clip for cable has the spring of certain clamping force.
Compared with prior art, the utlity model has following advantage:
