In recent years along with the fast development of intelligent grid, a series of variations have been also along with having occured in overhead line conductor, by initial simple transmission current, change a simultaneously comprehensive carrier of transmission current and signal into, and the OPPC wire just have such function.But at present the OPPC wire is installed in certain restriction is arranged on the power transmission tower, because the OPPC wire just has an OPPC junction box every a segment distance, and this OPPC junction box must be installed in iron tower of power transmission line cross-arm termination, but steel tower cross-arm termination is installed jumper string simultaneously again, therefore just causes the safe distance of cross-arm termination not enough.As depicted in figs. 1 and 2,1 ' is cross-arm, and 4 ' is the wire string, and 5 ' is jumper string, can find out on Fig. 1 and Fig. 2, the 1 ' design of existing standard tower cross-arm can't satisfy hang simultaneously OPPC junction box and jumper string 5 ' safe distance requirement.In order in the 110kV power transmission engineering, to use New O PPC wire and OPPC junction box, need development to be suitable for hanging the 110kV power transmission tower Novel crossarm of OPPC junction box.
The utility model content
The utility model aims to provide a kind of power transmission tower cross-arm, so that can guarantee safe distance when hanging at the same time wire jumper string and OPPC junction box.
To achieve these goals, according to an aspect of the present utility model, provide a kind of power transmission tower cross-arm, having comprised: the cross-arm body; Lug boss is arranged on the end of cross-arm body; And the support portion, the middle part is connected on the lug boss, and two ends are away from the horizontal expansion of cross-arm body.
Further, the support portion arranges with the cross-arm body is vertical.
Further, the support portion is support bar.
Further, support bar is two, and parallel and interval arranges, and two support bars connect by connecting rod.
Further, support bar is connected by spiro connecting piece with lug boss.
Further, lug boss is connected with cross-arm body one.
Further, lug boss and cross-arm body are flexibly connected.
Further, the wire string that also comprises the both sides, end that are arranged on the cross-arm body.
Further, lug boss is not less than 0.5m along the length of the bearing of trend of cross-arm body, and the longitudinal length of support portion is not less than 2.1m.
The power transmission tower cross-arm that the utility model provides has lug boss and support portion, by the wire jumper string being arranged on the two ends of support portion, the OPPC set of terminal box is in the centre of support portion, can be installed on safely on the power transmission tower so that have the OPPC wire that electric current and information transmits simultaneously, for providing a kind of brand-new technical scheme based on the intelligent transmission line construction of OPPC technology and the application of novel conductive wire.
