Problems solved by technology

Outdoor overhead cables are a crucial link in power transmission, because the outdoors are affected by various factors such as climatic conditions, especially in mountainous areas and areas with high altitudes, such as rain, snow, freezing rain and other harsh weather, which will make the Power facilities such as outdoor overhead cables are damaged, and may even cause large-scale power outages, causing serious losses to the national economy
For example, from the end of 2007 to the beginning of 2008, the blizzard, freezing rain and snow condensation disaster weather caused serious damage to the power facilities in most provinces of our country, and caused great losses to the country and the people.

Abstract

The invention relates to a process method for a sheath of a power transmission and transformation wire, in particular to a method for preparing an anti-freezing flame-retardant sheath. The method is characterized in that the anti-freezing flame-retardant sheath is prepared from the following raw materials in percentage by weight: 50 portions of base material, 1 portion of vulcanizing agent, 40 portions of strengthened plasticizer, 2 portions of antiager, 2 portions of damp-proof and moisture-proof separant and 5 portions of flame retardant. The anti-freezing flame-retardant sheath is preparedfrom novel high molecular materials, can protect power transmission and transformation wires, and can achieve the anti-freezing and flame-retardant effect.

Description

technical field [0001] The invention relates to a process method for a protective cover for power transmission and transformation wires, in particular to a preparation method for an anti-freezing and flame-retardant protective cover. Background technique [0002] As an important secondary energy source, electric energy has been widely used in various fields of the national economy and people's daily life. The level of power development and the degree of electrification reflect a country's economic level and people's living standards from a certain perspective. Outdoor overhead cables are a crucial link in power transmission, because the outdoors are affected by various factors such as climatic conditions, especially in mountainous areas and areas with high altitudes, such as rain, snow, freezing rain and other harsh weather, which will make the Power facilities such as outdoor overhead cables are damaged, and may even cause large-scale power outages, causing serious losses ...
