The cradle portion and through-type overhanging arm are hollow setting.
The spherical shell and conducting wire fixed part are hollow out setting.
It is had the beneficial effect that caused by the utility model.
1, the strain hardware fitting of the utility model is used for compound cross-arm, so that anchor support is existed by the way of conductive adaptive corner
It can be connect with conducting wire in 0-60 ° of angle range using same connecting component, fitting, the setting of the utility model can be cancelled absolutely
Complicated fitting in the tradition cross-arm such as edge substring, wire jumper, the connection that can significantly simplify conducting wire and anchor support design, and reduce expense,
Improve processing, installation effectiveness.
2, using the through-type strain hardware fitting of the self-adjustable of the utility model, the fitting connection on power transmission tower by wire tension can
Electrification, the pulling force and electric energy of conducting wire all pass through same path and transmit, and save and the usable " insulator of transmitting electricity is separately provided
String-wire jumper " system.
3, the connecting portion of conducting wire fitting and power transmission tower has flexural pivot, can be within the scope of 0-60 ° in vertical, horizontal plane
It is adapted to automatically according to conducting wire sag, power transmission tower corner degree, is not required to process more set connectors.In the setting of flexural pivot, power transmission tower with
The angled setting of bar band of flexural pivot connection, both guarantees that set of device can meet the needs of 0-60 ° of corner of power transmission tower.
