Electro-corrosion prevention ADSS optical fiber erecting structure

Abstract

The invention relates to an electro-corrosion prevention ADSS optical fiber erecting structure comprising a corner tower fixing member and a tower pole fixing member. The corner tower fixing member comprises a first U-shaped fitting. One end of the first U-shaped fitting is fixed on the corner tower, and the other end is connected with a first insulating ring. The first insulating ring is fixedlyconnected with a heart-shaped connecting ring which is connected with a strain clamp. The strain clamp is internally provided with an ADSS optical fiber. The external layer of the ADSS optical fiber is provided with a strain inner twisted wire. The external layer of the ADSS optical fiber is also provided with a first spiral shock reducer. The tower pole fixing member comprises a second U-shaped fitting. One end of the second U-shaped fitting is fixed on the tower pole, and the other end of the second U-shaped fitting is connected with a second insulating ring. The other end of the second insulating ring is connected with a suspension body which is internally provided with a rubber clamp block, a suspension outer twisted wire and a suspension inner twisted wire in turn. The suspension inner twisted wire is internally provided with the ADSS optical fiber. The ADSS optical fiber is also externally sleeved by a first spiral shock reducer.

Description

technical field [0001] The invention belongs to the field of optical fiber erection equipment, and in particular relates to an anti-electric corrosion ADSS optical fiber erection structure. Background technique [0002] ADSS optical cable has been widely used in power communication system because of its unique characteristics. Most of the ADSS optical cables are used for communication transformation of old lines, and are installed on the original power towers and below the high-voltage power lines through hoops, cross arms, suspension fittings or tension fittings. Although the ADSS optical cable has an all-dielectric structure, the optical cable is erected near the high-voltage wire, and there is an electric field in the space around the wire. Under certain conditions, it is very easy to cause electrical corrosion and cause the cable to break. [0003] Accidents caused by electrical corrosion of ADSS optical cables all occurred on 110kV lines, and the rod type was a steel p...
