Embodiment 1

[0022] like figure 1 As shown, an improved optical cable clamp includes a U-shaped hanging ring 1, a right-angle ring is hung under the U-shaped hanging ring 1, a suspension head 4 is hung under the right-angle ring, and a discharge part is set on the right-angle ring. It includes a metal discharge layer 32 , an insulating layer 31 is provided between the metal discharge layer 32 and the suspension head 4 , and a plurality of spike protrusions 33 are provided on the upper surface of the metal discharge layer 32 .

[0023] In order to control the electrical corrosion of the ADSS optical cable, the ground leakage current can be controlled below 0.3 mA, so that a continuous arc cannot be formed, and the electrical corrosion of the ADSS optical cable will basically not occur. In the present invention, a discharge part is arranged between the ADSS optical cable and the clamp, and the ground leakage current part on the ADSS optical cable is released through the metal discharge layer...

Abstract

The invention discloses an improved optical cable clamp, which comprises a U-shaped hanging ring, wherein a right-angular ring is hung under the U-shaped hanging ring; a hanging head is hung under theright-angular ring. The improved optical cable clamp is characterized in that a discharging component is arranged on the right-angular ring in a sleeving way; the discharging component comprises a metal discharging layer; an insulation layer is arranged between the metal discharging layer and the hanging head; the upper surface of the meal discharging layer is provided with a plurality of spine bulges. Through the metal discharging layer arranged on the discharging component, grounding leakage current on an ADSS (all-dielectric self-supporting optic fiber cable) can be partially released; particularly through the spine bulges arranged on the metal discharging layer, the discharging effect can be effectively achieved, so that the intensity of the grounding leakage current can be reduced; the formation of continuous electric arc on the ADSS can be prevented.

Description

technical field [0001] The invention relates to the field of optical cable clamps, in particular to an improved optical cable clamp. Background technique [0002] On the power transmission line, use the ready-made tower to install the communication line. Because of its unique mechanism, good insulation, high temperature resistance and high tensile strength, the ADSS optical cable can provide a fast and economical transmission channel in the power system. It is favored by electric communication. [0003] ADSS optical cables are widely used in the power system. Due to the influence of construction quality and natural environmental factors, the electrical corrosion of ADSS optical cables used in the external environment is very serious, and the phenomenon of optical cable breakage occurs from time to time. The mechanism of ADSS optical cable electric corrosion phenomenon is that the ADSS optical cable is near the high-voltage wire, and there is a space electric field around th...
