Problems solved by technology

Because the iron cross arm is perishable, rusted, and has a short service life, and the support strength of a single hoop to the iron cross arm is average, it is prone to safety hazards
In addition, ceramic insulators are fragile during transportation

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] This preferred embodiment is Figure 1 to Figure 3 Shown is a support for high-voltage wires used on utility poles, including two parallel arms 2 and 6-wire insulators 3 fixed on the horizontal plates of the arms 2, and the vertical plates of the arms 2 are connected to the wires through the first hoop The rod 1 is fixed; it also includes four oblique support rods 7 and a second hoop fixed to the utility pole, the second hoop is arranged below the first hoop, between the end of the vertical plate of the cross arm 2 and the second hoop All are connected by a diagonal support rod 7. Among them, the crossarm 2 is made of FRP, which has corrosion resistance, good insulation performance, light weight and high strength; the insulator 3 is made of glass fiber impregnated with vinyl ester resin through the existing FRP winding process, and has...

Abstract

The invention provides a high-voltage line support used on a telegraph pole. The high-voltage line support comprises two parallel cross arms and a plurality of insulators fixed to horizontal plates of the cross arms. Perpendicular plates of the cross arms are fixedly connected with the telegraph pole through first hoops. The high-voltage line support further comprises second hoops fixedly connected with the telegraph pole, the second hoops are arranged below the first hoops, and inclined supporting rods are connected between the ends of the second hoops and the ends of the perpendicular plates of the cross arms. The cross arms are made of glass fiber reinforced plastics, and the insulators are formed by winding glass fibers steeped with vinyl ester resin. The high-voltage line support has the advantages that firstly, the cross arms made of the glass fiber reinforced plastics are adopted, so that the high-voltage line support is low in weight, high in strength, resistant to corrosion, good in insulation performance and long in service life, and the glass fiber insulators made based on the winding technology are not prone to breakage; secondly, the second hoops connected with the two ends of the cross arms through the inclined supporting rods are additionally arranged below the first hoops, the supporting strength is increased, potential safety hazards are reduced, after the first hoops are corroded and damaged, a supporting guarantee still exists, and certain first-aid repair time can be provided.

Description

technical field [0001] The invention relates to a high-voltage line support used on electric poles. Background technique [0002] The existing high-voltage line bracket used on utility poles includes two iron cross arms arranged in parallel and four or six wire ceramic insulators on the fixed iron cross arm horizontal plate, and the iron cross arm vertical plate is fixed on the wire by a hoop on the pole. Because the iron cross arm is perishable, rusted, and has a short service life, and the support strength of a single hoop to the iron cross arm is average, it is prone to safety hazards. In addition, ceramic insulators are fragile during transportation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-voltage line support for utility poles with corrosion resistance, long service life and high support strength. [0004] The technical solution adopted by the present invention to solve the above-mentioned ...
