To achieve these goals, the utility model technical scheme of taking is a kind of steel tower power transmission line jockey provided, a kind of steel tower power transmission line jockey, comprise composite insulator, insulated gold utensil, described composite insulator is connected by bolt with insulated gold utensil, insulated gold utensil is by strain clamp, insulating cover forms, described insulating cover is arranged on the outside of strain clamp, strain clamp side is provided with power transmission line connector, strain clamp opposite side is provided with wire jumper connector, described composite insulator one end is provided with ball-eye, composite insulator and strain clamp junction are provided with grading ring, ball-eye one end is provided with connection gold utensil.
Preferably, described composite insulator comprises insulation mandrel, silicon rubber umbrella and is arranged on the end gold utensil at insulation mandrel two ends, and silicon rubber umbrella is arranged on insulation mandrel outer surface.
Preferably, described insulation mandrel is made up of epoxy resin fiberglass.
Preferably, described connection gold utensil comprises prolongation ring and link plate, extends ring and is connected with ball-eye, and link plate is connected with prolongation ring.
Employing the beneficial effects of the utility model are: this steel tower power transmission line jockey by using composite insulator in insulated hardware string, both are combined into the utility model device, solve during existing strain insulator-string uses the pollution flashover problem occurred, insulated gold utensil has that grip is reliable, to wire not damaged, compact conformation, easy for installation, insulation is reliable, the advantage of obvious energy conservation, the advantages such as the mechanical strength in conjunction with composite strain insulator is high, resistance to soiling is strong, lightweight are the optimum devices that traction connects power transmission line.By being provided with grading ring at composite insulator and strain clamp junction, junction surrounding electric field can be made to be uniformly distributed, when insulator generation flashover, also the booster action that protection insulator silicon rubber surface and parts thereof are burnt out by electric arc is had, described composite insulator comprises insulation mandrel, silicon rubber umbrella and be arranged on the end gold utensil at insulation mandrel two ends, silicon rubber umbrella mainly plays protection plug, block sleet, increase the effect of creepage distance and product external insulation, there is good hydrophobicity and animal migration, and it is good corrosion-resistant, ageing-resistant, the performances such as electric insulation, and there is very high pollution flashover voltage and the energy of resistance to fragility, voltage's distribiuting is even, compared with porcelain its under equal conditions flashover voltage be more than 2 times of porcelain.Described insulation mandrel is made up of epoxy resin fiberglass, has very high tensile strength, generally can reach more than 600Mpa, 2 times of common iron, 5 ~ 8 times of ceramic material, and there is good dielectric property and chemerosiveness resistent, also have good counter-bending fatigue, creep resistant and impact resistance.The advantages such as this steel tower power transmission line jockey is easy for installation, insulation is reliable, resistance to soiling is strong, obvious energy conservation, are applicable in industry extensively promoting.
