Abstract

The invention relates to a power transmission overhead line cable isolation rod. The rod comprises a connecting plate, a telescopic device and a clamping device, the telescopic device is mounted on the connecting plate; the clamping device is mounted on the telescopic device; according to the invention, the following problems existing when a conventional cable isolation rod isolates a cable can besolved: firstly, a traditional cable isolation rod cannot stably clamp a cable, the clamping direction of the cable isolation rod to the cable is single, clamping force is insufficient, installationis inconvenient, the cable isolation rod cannot bear severe weather in the later period, the cable isolation rod is prone to loosening under the condition of large wind power, the cable isolation rodfalls off from the high altitude, and large potential safety hazards exist; and 2, the isolation distance of the existing cable isolation rod to the cables is fixed, and the interval length between the cables cannot be adjusted. Thus, according to the invention, the stability of cable isolation can be improved, and the isolation distance between the cables can be adjusted.

Description

technical field

[0001] The invention relates to the technical field of power transmission, in particular to a power transmission overhead line cable isolation rod. Background technique

[0002] A cable is an electrical energy or signal transmission device, usually composed of several wires or groups of wires. Cables are widely used and involve almost every industry. They are often used in power systems, information transmission systems, electrical equipment, and electrical instruments. When using cables, the cables need to be split into multiple wires during the erection process. In order to ensure that the distance between the split wire bundles remains unchanged to meet the electrical performance, it is necessary to install spacers between parallel wires to avoid overhead. The vibration of the cable under the action of wind or severe weather conditions will cause damage to the cable line.

[0003] However, the current cable isolation rods have the following problems when ...
