The present invention will take following technical measures to realize: it comprises bolt; Mainly become two wire clamps and form jumper clamp by two corresponding semi-circular three; Between two or three change, two wire clamps, establish the duplex fishplate bar; It is fixing to become the connection of two wire clamps through bolt with two or three, and two or three change, two wire clamps are fixedly connected with device clamp.
Described three become two wire clamps; Be that semi-ring is provided with vertically that a side is three in semi-circular framework upper edge, opposite side is two equally distributed terminal board; And radially establish the metal link of reinforcement terminal board in semi-circular framework symmetrical centre, and with the reinforcement terminal board with the duplex fishplate bar, be fixedly connected with device clamp along the set terminal board of semi-ring.
Described duplex fishplate bar is that two center symmetric figures connect plate, and both sides are protruded and are provided with three and become the corresponding terminal board of reinforcement terminal board on two wire clamps, also are reserved with the weight installing hole on this connection plate.
Described device clamp is made up of head, tail two parts, and its head outer surface is semicircle, and lower surface is the plane, and is fixedly connected along the set terminal board of semi-ring, and afterbody is tubular and conductor compression jointing.
The present invention is owing to taked said structure; Be provided with particularly that two one constitute three become two wire clamps and gusset piece, device clamp combination; Six changes, four bridle wire apparatus of the present invention are suspended on the strain tower through connecting gold utensil and insulator, and are in the center of whole wire jumper.The mechanical load that six changes, four bridle wire apparatus are born has been delivered on the strain tower through connection gold utensil, insulator; Thereby improved the stress condition of drainage wire clamp in the transmission line; Vibration and vibration have been reduced simultaneously; Reduced the alternate stress at strain clamp drainage plate place, avoided transmission line under the external force effect that stands wind, icing or accumulated snow, the drainage thread pinch off splits the generation with strain clamp drainage plate root phenomenon of rupture.Improved the transmission line reliability of operation.And because flexible jumper has suitable sag, during the wire jumper vibration, the integral body of bridle wire apparatus has certain pliability, need not to take the anti-measure of waving.Compare with adopting the aluminum pipe wire jumper simultaneously, can not only reduce half cost, processing and manufacturing is simple, convenient transportation and construction.And has reliable and stable, a suitable advantage such as widely popularize in the industry of novel uniqueness of inventive concept, structural design compact and reasonable, electric property.Technical scheme of the present invention compared with prior art has outstanding substantive distinguishing features and obvious improvement.
