Heat shrinkable tubes are often used in the electrical industry, it is necessary to understand the classification of electrical insulating materials products.

1, electrical insulation materials product Classification and naming principles overview

Electrical insulating materials products are divided into large categories, small categories, varieties and specifications four levels, and according to the product category to determine the naming principle.

2. Large category of insulating materials

That is, electrical insulating material products according to the application or process characteristics of classification, and digital representation as follows: 1-paint, resin and glue; 2-immersion fiber products; 31 laminated products; 41 plastic; s one mica products; 6-film, cat belt and compound products; 71 fiber products; 81 insulated liquid class.

3, Insulation materials small class

The electrical insulating material products in the large class are divided according to the scope and shape of use, and are represented by numbers as follows:

(1) Paint, resin and glue: 01 solvent impregnated paint; 11 solvent-free impregnated paint; 2-covered lacquer; 3-enamel; 4-gum paint, resin; 5– melt powder; 6~ a silicon steel sheet paint; 7-enameled wire lacquer; 81 glue.

(2) impregnated fiber Products: 01 cotton fiber lacquer cloth category; 21 lacquer silk; 31 synthetic fiber lacquer cloth; 41 glass fiber lacquer cloth; 5-mixed fabric category; 61 anti-Corona lacquer cloth; 71 lacquer tube category; 8-strapping belt class; 91 suitable material category.

(3) Laminated products Category: o-an organic substrate laminated plate class; 21 inorganic substrate laminates; 31 anti-Corona and magnetic conductive laminates; 4-coated foil laminates; 51 organic substrate laminated tubes; 61 inorganic substrate laminated tubes; 71 organic substrate laminated rods; 81 inorganic substrate laminated rods; and 91 drawing categories for the introduction of the type of Corona plate;.

(4) Plastic: o– wood powder filler plastic; 11 other organic filler plastic; 21 asbestos filler plastic; 31 glass fiber filler plastic; 41 mica filler plastic; 51 other mineral filler plastic; 61 filler free Plastic

(5) Mica Products: 0-one mica paper; 1-soft mica plate; 2-plastic mica plate; 41 Mica belt; 5-commutator Mica plate; 6-one electrothermal equipment Mica plate; 71 liner MICA plate; 81 Mica tip; 91 Mica tube.

(6) film, Cat belt and Composite Products Category: 0-thin film; 2-thin film drilling belt class; 31 rubber and fabric Weng belt class; 41 Resin impregnated soft composite materials; 5-thin film insulating paper and film glass lacquer composite foil; 6-thin film synthetic foil; 71 kinds of materials U-Foil class.

The large and small class numbers of electrical insulating materials are taken from 19 to 10, of which the number of vacancies is used for the future increase in product types and the appearance of new materials.

4, insulation material varieties and specifications

(1) variety is the electrical insulation material of the Tsuen this unit, where the main components and the same process of the same product belongs to the same variety.

(2) Specifications of electrical insulating materials products can be in size (thickness, diameter, length, width, etc.) of different requirements, in the variety of different specifications.

电工绝缘材料产品分类

热缩管在电工行业中经常用，我们有必要了解电工绝缘材料产品的分类。

1、电工绝缘材料产品分类和命名原则概述

电工绝缘材料产品分为大类、小类、品种及规格四级，并按产品大类确定命名原则。

2、绝缘材料大类

即电工绝缘材料产品按应用或工艺特征分类，并以数字代表如下:1-漆，树脂和胶类;2-浸演纤维制品类;3一层合制品类;4一塑料类;S一云母制品类;6-薄膜、猫带和复合制品类;7一纤维制品类;8一绝缘液体类。

3、绝缘材料小类

大类中的电工绝缘材料产品按使用范围及形态划分，并以数字代表如下:

(1)漆、树脂和胶类:0一有溶剂浸渍漆类;1一无溶剂浸渍漆类;2-覆盖漆类;3-瓷漆类;4-胶猫漆、树脂类;5–熔敷粉末类;6~一硅钢片漆类;7-漆包线漆类;8一胶类。

(2)浸渍纤维制品类:0一棉纤维漆布类;2一漆绸类;3一合成纤维漆布类;4一玻璃纤维漆布类;5-混织纤维漆布类;6一防电晕漆布类;7一漆管类;8-绑扎带类;9一适型材料类。

(3)层合制品类:o-一有机底材层合板类;2一无机底材层合板类;3一防电晕及导磁层合板类;4-覆钢箔层合板类;5一有机底材层合管类;6一无机底材层合管类;7一有机底材层合棒类;8一无机底材层合棒类;9一引拔制品类。

(4)塑料类:o–木粉填料塑料类;1一其他有机物填料塑料类;2一石棉填料塑料类;3一玻璃纤维填料塑料类;4一云母填料塑料类;5一其他矿物填料塑料类;6一无填料塑料类

(5)云母制品类:0-一云母纸类;1-柔软云母板类;2—塑型云母板类;4一云母带类;5-换向器云母板类;6-一电热设备云母板类;7一衬垫云母板类;8一云母梢类;9一云母管类。

(6)薄膜、猫带和复合制品类:0-薄膜类;2-薄膜钻带类;3一橡胶及织物翁带类;4一树脂浸渍柔软复合材料类;5-薄膜绝缘纸及薄膜玻璃漆布复合箔类;6-薄膜合成纤维纸复合箔类;7一多种材质u合箔类。

电工绝缘材料的大类及小类号均从0一9取10个号，其中空缺的号数供今后产品种类增加和新型材料出现时使用。

4、绝缘材料品种和规格

(1)品种是电工绝缘材料的荃本单元，凡主要组成成分和撰本工艺相同的产品属于同一品种。

(2)规格电工绝缘材料产品可按尺寸(厚度、直径、长度、宽度等)的不同要求，在品种内再划分不同规格。
