Lead fixing device and composite cross arm

Abstract

The invention discloses a lead fixing device. The lead fixing device is used for fixing a lead on the composite cross arm. The composite cross arm comprises an insulation core rod and an insulation layer which is covered outside the insulation core rod, the lead fixing device comprises a cross arm connection member and a lead fixing member, wherein the cross arm connection member is fixedly connected with outer periphery of the insulation core rod in a covering mode, the cross arm connection member abuts the insulation layer, the lead fixing member is provided with a wire duct used for accommodating a lead, and the leading fixing member is fixed at outer periphery of the cross arm connection member and is used for fixing the lead in the wire duct. The invention further discloses the composite cross arm. The lead fixing device is advantaged in that the cross arm connection member and the insulation core rod realize compact connection and has good sealing property, fracture of the insulation core rod can be effectively avoided, moreover, the wire duct used for accommodating the lead is arranged on the lead fixing member, through fixing the lead fixing member at the outer periphery of the cross arm connection member, the lead is fixed and limited in the wire duct, lead binding is not required, later maintenance workload is reduced, and engineering maintenance cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of power equipment, in particular to a wire fixing device and a composite cross arm. Background technique [0002] In the distribution network system, the erection method of the conductor below 35kV is usually cement pole and angle steel cross arm. Pin insulators are installed on the angle steel cross arm to fix the wires. It is attached to the insulator, so the wire needs to be tied to the pin insulator. The binding process is cumbersome and easy to loose after a long time. It needs regular maintenance and repair. [0003] The composite cross arm developed on the basis of the angle steel cross arm usually uses two methods to fix the wire: one is to drill holes on the composite cross arm, and install the above pin insulator to fix the wire. The wire still needs to be tied to the pin insulator. And punching holes on the composite crossarm will seriously affect the mechanical properties of the composite crossarm; th...
