The utility model adopts following technical scheme: a kind of single loop anchor support, it is characterized in that, comprise tower body, middle phase conductor wire jumper tower window, limit phase conductor cross-arm, middle phase conductor wire jumper support, ground wire cross-arm, described middle phase conductor wire jumper tower window is arranged at described tower body top, and the shape of described middle phase conductor wire jumper tower window is polygon; Described limit phase conductor cross-arm is arranged at the following edge of described middle phase conductor wire jumper tower window, for installing both sides phase strain insulator-string, both sides phase jumper string; Described middle phase conductor wire jumper Bracket setting is in the top of described middle phase conductor wire jumper tower window, and described middle phase conductor wire jumper support stretches out along line direction in " one " font; Described ground wire cross-arm is arranged at the upper end-face edge of described middle phase conductor wire jumper tower window, and the shape of described ground wire cross-arm is triangular in shape.
Preferably, the strain insulator-string hanging point of both sides phase conductor and jumper string hanging point are arranged on the phase conductor cross-arm of limit respectively, and both sides phase conductor adopts directly jumps or utilize limit phase conductor cross-arm installation jumper string to be connected.
Preferably, middle phase conductor strain insulator-string is arranged at the lower limb of middle phase conductor wire jumper tower window, middle phase conductor wire jumper tower window inside is provided with V-type jumper string, and the forward and backward two ends of phase conductor wire jumper support are respectively arranged with I type jumper string in " one " font, connects with the transition of phase conductor in realizing.
Preferably, when single loop cat head anchor support does to bore more tower use, ground wire cross-arm is arranged at the K Nodes of middle phase conductor wire jumper tower window, to compress ground wire height.
The beneficial effect that the utility model reaches: (1) three-phase conducting wire adopts single loop " horizontally " mode, effective minimizing tower head height, reduce tower weight, when the dry font anchor support of more conventional triangle arrangement is more conducive to preventing ice-shedding between wire or lead wire and earth wire produce flashover; (2) in, phase conductor adopts upwards around the cat-head transmission tower window pattern of jumping, by arranging polygon tower window at tower head top, middle phase both sides strain insulator-string can utilize polygon tower window upwards to lead to around jumper connection, achieves middle phase jumping wire to the electric clearance of tower window and tower window to the lightning protection of wire jumper; (3) on the top of middle phase conductor wire jumper tower window, phase conductor wire jumper support in " one " font is installed, before and after component, side adopts I type to jump string, the middle transition adopting V-type pendency jumping string to realize wire jumper connects, thus electrical distance requirement when effectively ensureing operation and wire jumper windage yaw; (4) ground wire adopts and hangs on middle phase conductor wire jumper tower window upper end-face edge, common anchor support uses the requirement meeting and lead, meet under ground wire ice-shedding wire spacing, when doing to bore more tower use, at the K Nodes of middle phase jumping wire tower window, ground wire cross-arm can be installed, lead with compression, the interfloor height of ground wire, meet the requirement that single loop drilling is got over.
