本篇介绍带电作业工具材料的分类及选用。通过对绝缘材料的讲解，熟悉各类常用绝缘材料、掌握带电作业工具绝缘材料的选择原则。以下内容还涉及了带电作业工具金属材料的选择原则。

 

This paper introduces the classification and selection of live working tools and materials. Through the explanation of insulating materials, familiar with all kinds of commonly used insulating materials, and master the selection principle of insulating materials for live working tools. The following also covers the selection principle of metal materials for live working tools.

 

 

常用绝缘材料的分类

 

Classification of common insulating materials

 

绝缘材料，又称电介质。它与导电材料相反，在一定电压作用下，只有极微的泄漏电流通过，可以认为是不导电的。绝缘材料的好坏，直接关系到带电作业的安全，因此制作带电作业工具的绝缘材料必须是电气性能优良、机械强度高、重量轻、吸水性低、耐老化、且易于加工。

 

Insulating material, also known as dielectric. In contrast to conductive materials, only a tiny leakage current passes through under a certain voltage, which can be considered as non-conductive. The quality of insulating materials is directly related to the safety of live working. Therefore, the insulating materials for making live working tools must have excellent electrical performance, high mechanical strength, light weight, low water absorption, aging resistance and easy processing.

 

 

 

我国目前带电作业使用的绝缘材料大致有下列几种

At present, the insulating materials used in live working in China are generally as follows:

 

 

 

绝缘板材：包括硬板和软板。其种类有层压制品，如3240环氧酚醛玻璃布板和工程塑料中的聚氯乙烯板、聚乙烯板等。

 

Insulating board: including hard board and soft board. Its types are laminated products, such as 3240 epoxy phenolic glass cloth board, PVC board and polyethylene board in engineering plastics, etc.

 

绝缘管材：包括硬管和软管。种类有层压制品，如3640环氧酚醛玻璃布管、带或丝的卷制品。

 

Insulating pipe: including hard pipe and hose. There are kinds of laminated products, such as 3640 epoxy phenolic glass cloth pipe, tape or silk roll products.

 

塑料薄膜：如聚丙烯、聚乙烯、聚氯乙烯、聚酯等塑料薄膜。

 

Plastic film: such as polypropylene, polyethylene, PVC, polyester and other plastic films.

 

橡胶：天然橡胶、人造橡胶、硅橡胶等。

 

Rubber: natural rubber, artificial rubber, silicone rubber, etc.

 

绝缘绳：天然蚕丝、人工化纤丝编织的，如尼龙绳、绵纶绳和蚕丝绳（分 生蚕丝绳和熟蚕丝绳两种），其中包括绞制、编织圆形绳及带状编织绳。

 

Insulating rope: natural silk and artificial silk woven, such as nylon rope, cotton fiber rope and silk rope (divided into raw silk rope and mature silk rope), including stranding, weaving round rope and ribbon weaving rope.

 

绝缘油、绝缘漆、绝缘粘合剂等。

Insulating oil, insulating paint, insulating adhesive, etc.
