Abstract
The utility model discloses a stringing device provided with a lead wire and serially arranged on a steel pipe pole in L shape. The stringing device comprises a steel pipe pole, a cross arm supporting rack is arranged on the steel pipe pole, one end of the cross arm supporting rack is connected with a first insulator string, the other end thereof is connected with a second insulator string, the other end of the first insulator string and the second insulator string is connected with the lead wire, and the first insulator string and the second insulator string form L-shaped serial arrangement. The cross arm supporting rack is arranged as an electric loop. The multi-loop steel pipe pole can not only reduce the land occupied by tower footings but also save the line corridor; in urban power transmission projects, the relocation of houses along the lines can be reduced, the cutting of the current trees and plants can be reduced, the environment protection and the land resource conservation are favorable, and simultaneously, the requirement that the rapid development of urban electric network networks needs high-voltage power transmission technology is satisfied, therefore, the status quo of crowded electric corridors is solved.
Description
Technical field
The utility model belongs to the electric power transmission device, is specifically related to a kind of wire-binding device.
Background technology
Along with fast development of national economy, promoted China's development of electric power industry urban distribution network construction fast development to need the technology of transmission of electricity of voltage levels.Existing voltage levels transmission of electricity wire-binding device all adopts the stringing tower.The stringing tower can set up the transmission pressure of voltage levels, but it exists the column foot floor space big, construction of line engineering complexity, the baroque defective of stringing tower.For the urban distribution network transmission of electricity, circuit corridor and column foot take up an area of more and more nervous and restricted, are difficult to satisfy the demands.
Summary of the invention
The purpose of this utility model is to provide that a kind of to take ground little, has lead L type string and is arranged in wire-binding device on the steel pipe pole, to address the above problem.
The technical solution of the utility model is: have lead L type string and be arranged in wire-binding device on the steel pipe pole, it comprises steel pipe pole, the cross-arm bracing frame is set on the steel pipe pole, one end of cross-arm bracing frame connects first insulator string, the other end of cross-arm bracing frame connects second insulator string, first insulator string is connected lead with the other end of second insulator string, and first insulator string and second insulator string constitute " L " type string and arrange.
The cross-arm bracing frame is pressed the power circuit setting.
Make the multiloop steel pipe pole not only can reduce the column foot occupation of land and more can save the circuit corridor; in the urban electric power power transmission engineering; reduce housing demolition along the line; reduce the existing trees vegetation of felling; help protecting environment and economize the land resource, satisfy the requirement that urban distribution network is built the technology of transmission of electricity of fast-developing needs voltage levels simultaneously.Thereby solve the crowded present situation in electric power corridor.
Description of drawings
Fig. 1 has lead L type string and is arranged in wire-binding device schematic diagram on the steel pipe pole.
Fig. 2 connects enlarged diagram near the cross-arm bracing frame of steel pipe rod end.
