Problems solved by technology
[0004] The above method describes a composite material pole forming process, but it is still used as the main structure of the transmission line, and the insulation method still adopts steel structure cross-arms with pin-type insulators or directly installs FRP cross-arms, and does not fully consider the FRP pole itself. Composed of insulating materials, high-voltage composite poles without cross-arms and pin insulators, and the width of the line corridor cannot be reduced

Abstract
The invention relates to a composite electric pole. The electric pole comprises a main rod with a hollow conical pipe structure, sealing end covers, multiple wires and multiple outer insulating full skirts. The upper end and the lower end of the man rod are sealed through the sealing end covers, so that rainwater and underground moisture are prevented from entering the electric pole, the multiplewires are vertically arranged on the main rod at a certain interval, the outer insulating full skirts are vertically arranged on the main rod, each outer insulating full skirt is arranged on one wire,the main rod is made of a composite, the corrosion resistance and the aging resistance of the electric pole are good, the composite electric pole can be applied to high-salt-mist, high-corrosion andhigh-pollution environments, has excellent mechanical performance and a high strength safety coefficient, and is not prone to break under load abrupt change working conditions such as strong wind, wire breakage and icing, in addition, the composite electric pole is low in mass, can be rapidly transported and mounted without large machines during mountainous area operation, and is especially suitable for first-aid repair such as rescue and relief work.
Description
technical field [0001] The invention belongs to the technical field of electric poles, and in particular relates to an electric pole made of composite materials. Background technique [0002] At present, high-voltage transmission lines use concrete poles, FRP poles, and steel pipe poles as the main structure. The insulation method uses steel structure crossarms with pin insulators or directly installs FRP crossarms to meet insulation and lightning protection requirements. [0003] Chinese invention patent CN106285159A discloses a composite material electric pole and its preparation method. Through layer design, suitable fiber material is selected to obtain an electric pole with excellent fatigue resistance; it includes at least one winding group, preferably 1-3 windings groups, at least one winding group sequentially includes a helical winding layer, a reinforcing layer and a hoop winding layer from the inside to the outside. [0004] The above method describes a composite ...
