3 Definitions
Classification, name and model compilation methods of electrical insulation materials productsTest methods for electrical resin-impregnated glass fiber non-weft binding tape3.1 Electrical resin-impregnated glass fiber non-weft binding tape (abbreviated as non-weft tape) is a semi-cured strip material with a certain width made of treated unidirectional continuous alkali-free glass fiber yarn with or without twist, impregnated with thermosetting resin, and used for fastening and binding in electrical equipment. 3.1.1 High-strength glass fiber non-weft binding tape is a glass fiber non-weft binding tape made of high-strength twisted or untwisted glass fiber yarn as the base material. 3.1.2 Mesh non-weft tape
A mesh non-weft tape when pulled horizontally.
3.2 Lathless tape reel (hereinafter referred to as tape reel)
A type of lathless tape supply in which the lathless tape has no axial displacement during winding. 3.3 Lathless tape roll (hereinafter referred to as tape roll)
A type of lathless tape supply in which the lathless tape is uniformly displaced along the axial direction during winding. 4 Product classification
4.1 Varieties and specifications
Lathless tape belongs to the binding tape category among impregnated fiber products. Varieties are divided according to the main components, substrates and characteristics of the impregnated resin. Specifications are divided according to width, thickness and length (if necessary). 4.2 Product code
4.2.1 Naming method
The product name consists of the following three parts:
One or more technical characteristics that must be specified when necessary; a.
The main components of the impregnated resin, if it is a modified resin, it should also be indicated; b.-
Substrate and basic name, that is, glass fiber lathless binding tape. c.
Example: Oil-resistant modified epoxy resin high-strength glass fiber mesh non-weft binding tape refers to a mesh non-weft binding tape with oil-resistant properties, the main component of the impregnated resin is the modified epoxy resin of the Ministry of Machinery and Electronics Industry 1992-06-16

, and the base material is high-strength glass fiber yarn. 4.2.2 Model
The preparation of product models shall be in accordance with the provisions of Chapters 14, 15 and 16 of JB2197. Non-weft binding tapes with special technical characteristics are indicated by specific additional letters. The letter W. indicates a non-weft binding tape with a mesh structure. Example: 2844-W epoxy resin high-strength glass fiber mesh non-weft binding tape. 5 General requirements
5.1 Appearance
The reel (roll) should be tightly wound, the reel surface should be neat, easy to unwind and non-sticky. The non-weft tape should be evenly glued, with no organic impurities on the surface, with a certain degree of stickiness and softness, and the tape surface should be free of creases, cracks and damage. 5.2 Joints
There should be no more than one joint per reel (roll) of non-weft tape. The joint should not hinder the unwinding of the non-weft tape. The joints should be clearly marked. The length of each section of the reel shall not be less than 50m. The length of each section of the roll shall not be less than 200m. 5.3. Dimensions
The length of each reel (roll) of non-weft tape shall be estimated according to the net mass, bandwidth and quantity of the reel (roll). The thickness, width and length shall be specified in the product standard. If not specified, they shall be measured according to the methods specified in Chapters 4 to 6 of JB/T6236.2. The nominal values ​​and limit tolerances are shown in Table 1. Other specifications shall be determined by negotiation between the supply and demand parties. 6 Inspection rules
6.1 The non-weft tape shall be subjected to factory inspection and type inspection. 6.2 The type inspection items shall be specified in the product standard. Type inspection shall be carried out at least once every three months. Type inspection shall also be carried out when the raw materials or process conditions are changed.
6.3 The product batch, sampling method and factory inspection items shall be specified in the product standard. Each batch of non-weft tape shall be subjected to factory inspection, and the products can be shipped only after passing the inspection. The manufacturer shall ensure that the shipped products meet all technical requirements in the product standard. 6.4 When any of the inspection results does not meet the technical requirements, double sampling shall be conducted from the batch of non-weft tape, and the double samples shall be divided into two groups and the inspection shall be repeated. If one group still does not meet the requirements, the batch of non-weft tape is unqualified. 6.5 The manufacturer shall provide product inspection reports when the user unit requires them. The user unit may inspect the products, and when the products are found to be unqualified, they shall report to the manufacturer within the specified storage period. 7 Marking, packaging, transportation, storage
7.1 The inner diameter of the reel is 76+0.2mm. Each reel is first wrapped with plastic film and then packed with plastic bags. Padding is required for positioning when packing. The inner diameter of the core of the reel is 76+0.2mm. The shaft length is 174±2 or 270±2mm, which can also be determined by negotiation between the supply and demand parties. Each reel must be packed with plastic bags and padded for positioning when packing. The net weight of each box shall not exceed 20kg.
