The utility model content
The utility model technical issues that need to address are to provide a kind of little single telegram in reply cable of 220kV terminal steel pole tower of floor space that is applicable to the urban congestion location.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The single telegram in reply cable of 220kV terminal steel pole tower comprises the high bar and the low bar that arrange perpendicular to ground, and the top of described low bar and middle part are connected with high bar with lower transverse beam by parallel top rail respectively;
Wherein, the both sides of described high masthead section arrange respectively the upper cross-arm that be used for hang ground wire vertical with top rail with high bar, one side of the high bar between described upper cross-arm and top rail arranges respectively the cross-arm that be used for hang upper phase conductor vertical with top rail with high bar, and the both sides of described low masthead section arrange respectively the lower cross-arm that be used for hang lower phase conductor vertical with top rail with low bar;
Described high bar connects cross-arm one side in the position correspondence of top rail the high bar terminal platform that be used for install phase cable terminal and upper phase arrester vertical with top rail with high bar is set respectively, and the both sides that described low bar connects the lower transverse beam position arrange respectively the low bar terminal platform that be used for install lower phase cable terminal and lower phase arrester vertical with lower transverse beam with low bar.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is as follows:
The utility model adopts the two bar designs of height, and the distance of having dwindled outdoor cable terminals and trolley line hanging wire point has been removed the bracing wire of cable termination tower, facilitates the Maintenance and Repair of operations staff's upper boom.Two lower phase cable terminals are positioned on low bar terminal platform, and upper phase cable terminal is positioned on high bar terminal platform, and the whole height of reduction bar can be stablized the outdoor cable terminals simultaneously, is the safe operation establish a firm foundation.The utility model satisfies in " 110kV～750kV overhead transmission line design specifications ", and the horizontal-shift of ground wire opposite side wire-protecting angle, two ground distance between centers of tracks, span central authorities lead wire and earth wire spacing, ground wire and adjacent wires is apart from requiring.The utlity model has reasonable in design, stressed safe and reliable, be easy to the obviously advantage such as processing, installation, good looking appearance.
