Novel composite insulated cross arm for power transmission line pole tower

Abstract

The invention discloses a novel composite insulated cross arm for a power transmission line pole tower, and relates to the technical field of cross arms. The novel composite insulated cross arm comprises a cross arm horizontal rod and a connecting plate; the top of the cross arm horizontal rod is fixedly connected with the bottom of the connecting plate, and the two sides of the top of the cross arm horizontal rod are fixedly connected with a vertical stable box; and fixing clamping grooves are formed in the two sides in the vertical stable box correspondingly. According to the novel compositeinsulated cross arm for the power transmission line pole tower, after the insulated cross arm is mounted completely, a worker can make an extending clamping rod be separated from the fixing clampinggroove by pulling a lifting block according to the specific horizontal height of a power transmission cable, thus the height of a placement tray is changed by adjusting the height of a vertical supporting rod, the problem that the cross arm horizontal rod is not on the same horizon, consequently cables cannot be stably adjusted and fixed is solved, through holes formed in the surface of the connecting plate, the insulated cross arm and the pole tower can be connected through bolts, and connecting stability is further improved.

Description

technical field [0001] The invention relates to the technical field of cross arms, in particular to a novel composite material insulating cross arm for power transmission line towers. Background technique [0002] The transmission line is realized by using a transformer to boost the electric energy generated by the generator, and then connecting it to the transmission line through control equipment such as a circuit breaker. Structural forms, transmission lines are divided into overhead transmission lines and cable lines. The overhead transmission line is composed of line towers, wires, insulators, line fittings, guy wires, tower foundations, grounding devices, etc., and is erected above the ground. According to the nature of the transmission current, power transmission is divided into AC transmission and DC transmission. The first successful realization of direct current transmission. However, because the voltage of DC transmission was difficult to continue to increase u...
