Abstract

The invention discloses a tower cross arm member, comprising a frame, a protective layer covering the outer surface of the frame, and a shed group cast outside the protective layer. The section of the frame is D shaped, formed of two mutually perpendicular right-angle sides and an arc. The frame is formed by connecting steel angels or plates. The tower cross arm member according to the above manner has the advantages such as high mechanical strength, high rigidity, low deformation, weatherability, stressing reasonableness, material efficiency and cost efficiency and is applicable to 500 kV overhead transmission lines.

Description

technical field

[0001] The invention relates to the field of iron tower cross arms, in particular to an iron tower cross arm component. Background technique

[0002] At present, in the power transmission and distribution system, the cross arm is widely used as a supporting member in the application. The insulating cross-arm is generally equipped with silicone rubber umbrella groups or ceramic umbrella groups, so as to increase the creepage distance, improve the insulation level of the cross-arm, and reduce the transmission corridor of the cross-arm.

[0003] At present, there are two typical structural types of composite material towers in foreign countries: one is a tubular composite material pole developed by Canadian RS company, which is widely used in overhead lines of 10kV and 132kV voltage levels in the Alberta area. The second is a 220kV lattice composite tower jointly developed by San Diego Gas & Electric (SDGE) and Southern California Edison (SCE). Due to the compl...
