Chapter 3　Insulating Tools and Instruments

Insulating tools for live working shall have good electrical insulation properties and high mechanical strength.At the same time,they shall also have the characteristics of low hygroscopicity,aging resistance,light weight,convenient operation and damage prevention.At present,insulating tools for live working can be roughly classified into three types:hard insulating tools,soft insulating tools and other insulating tools.Hard insulating tools mainly refer to tools with insulating tubes,rods and plates as the main body.Soft insulating tools mainly refer to tools with insulating rope as the main body.Other insulating tools refer to insulated tackles and insulated stringing tools,which have the characteristics of both hard and soft insulating tools.(https://www.daowen.com)
