However, the former is costly and makes later operation and maintenance more difficult. Although the latter costs less, it is often difficult to obtain the consent of residents due to the impact on the appearance of the houses and the signals of wireless communication equipment in the houses.

Abstract

A device for reducing electromagnetic radiation of transmission lines comprises a jacket which is a cylinder with a hollow middle and two open ends. An electromagnetic shielding layer is arranged inside the jacket. The jacket is provided with an opening along the axial direction, and sleeves a transmission line through the opening. By adopting the device, the intensity of electromagnetic radiation of overhead transmission lines can be greatly reduced, the contradiction between offline residents and the power supply department can be resolved, and the cost of line renovation can be reduced.

Description

technical field [0001] The invention relates to a device for reducing electromagnetic radiation of transmission lines. Background technique [0002] The transmission line conductors in operation will produce a certain amount of electromagnetic radiation, and the radiation intensity will continue to attenuate with the increase of distance. my country has a vast territory, and overhead transmission lines are distributed in many areas. It is inevitable that the lines will pass through residential areas or densely populated areas. Electromagnetic radiation of transmission line wires often leads to disputes between residents in these areas and power supply departments. There are two commonly used solutions, one is to replace the overhead transmission lines across residential areas with cables into the ground, and the other is to build shielding cages outside residential buildings. However, the former is costly and makes later operation and maintenance more difficult. Although th...
