The utility model content
For overcoming the deficiency of prior art, it is a kind of simple in structure that the utility model provides, and the double back transmission line double T that applicability is good connects the difference shaft tower.
The utility model technical scheme that adopts of dealing with problems is:
A kind of double circuit line double T that realizes connects the difference shaft tower of usefulness; Comprise shaft; Said shaft upper surface is fixedly connected with the ground wire cross-arm; Said shaft is fixedly connected with at least 6 T font lead cross-arms that keep at a certain distance away respectively from top to bottom, and said lead cross-arm is divided into two loops up and down, and the lead cross-arm installation direction in same loop is identical and opposite with the installation direction in another loop.
Further improvement as such scheme; Said lead cross-arm is made up of vertical cross-arm and horizontal cross-arm; Said vertical cross-arm is vertically divided equally and is fixedly installed on the shaft, and an end vertical fixing of said horizontal cross-arm is installed on the shaft of vertical cross-arm lower limb certain distance.
As the further improvement of such scheme, said vertical cross-arm adopts bolt to be connected with shaft respectively with horizontal cross-arm.
As the further improvement of such scheme, said ground wire cross-arm structure is cross.
The beneficial effect of the utility model: the utility model adopts two times reverse T font lead cross-arms that keep at a certain distance away; Satisfy the requirement of double-circuit line hanging wire, utilize the characteristics of the T type structure of lead cross-arm, through corresponding electric connecting mode; Bilingual mouthful of realization double-circuit line or double T connect and enter the station; Not only reduced construction costs, solved the shaft tower expropriation of land difficult problem under the anxiety situation of circuit corridor, simultaneously because vertical cross-arm uses bolt to be connected with horizontal cross-arm and shaft; Easy accessibility, operation maintenance are convenient more.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of the utility model T type lead cross-arm;
