24、 series which deals with insulating materials for use in electrical equipment built up from mica splittings or mica paper, with or without reinforcement, and with mica paper in its pure state.The series consists of the following three parts: Part 1: Definitions and general requirements (IEC 60371-1)

25、; Part 2: Methods of test (IEC 60371-2); Part 3: Specifications for individual materials (IEC 60371-3). This standard contains one of the sheets comprising part 3, as follows: Sheet 7: Polyester film mica paper with an epoxy resin binder for single conductor taping.“1 ScopeThis International Standar

26、d specifies the requirements for an electrical insulating material containing mica paper with polyester film and with an epoxy resin binder for single conductor taping. The material is supplied in a flexible state with the resin in the B-stage for final cure after application. It is supplied in roll

27、 form. This specification refers only to single film, although compositions with polyester film facings of various thicknesses are available. The specification covers material having a nominal thickness from 0,07 mm to 0,12 mm.Materials which conform to this specification meet established levels of

28、performance. However, the selection of a material for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone.!Safety warning:It is the responsibility of the user of the methods contained or re

29、ferred to in this document to ensure that they are used in a safe manner.“2 Normative referencesThe following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were va

37、terial (as received)6.1 GeneralAll materials in any one consignment shall have the same properties, within the limits of this specification, throughout the length of each roll.The surfaces shall be uniform and free from defects such as bubbles, pin-holes, creases and flaws.The roll shall be capable

38、of being unrolled continuously without damage, and the force required to unroll the material shall be substantially uniform.To prevent damage to the mica paper component during winding, the unwinding tension shall be less than 75 % of the minimum allowable tensile strength.Unless otherwise specified

39、 in the purchase contract, the material shall be rolled with the mica surface on the outside.6.2 WidthThis specification contains no requirements for widths of tape. However, the following widths are preferred: 6 mm, 8 mm, 10 mm, 12 mm, 15 mm and 20 mm.The tolerance on the width of the material shal

40、l be as in Table 2. The maximum trimmed width of full width material and sheet normally available is 1 000 mm. Table 2 Tolerance on width6.3 Thickness!Measure the thickness in accordance with Clause 4 of IEC 60371-2, using the apparatus given in 4.1.1 of that standard, making 10 measurements of one

41、thickness of material.“ The measured values shall be in accordance with the requirements given in Table 1.6.4 LengthThere are no requirements in this specification for roll length, and these should therefore be subject to the purchase contract.6.5 CoresThe tape shall be compactly wound on cores of 5

42、5 mm or 76 mm interior diameter which shall be free of sharp edges. The width of the cores should be subject to the purchase contract.6.6 JoinsThe number of rolls with joins shall be limited to 25 % of any one consignment. Rolls of length less than 100 m shall contain no more than one join.For rolls

43、 of length more than or equal to 100 m, the number of joins should be subject to the purchase contract. Method of making the joins should be subject to the purchase contract.6.7 StiffnessThe stiffness of the material should be subject to the purchase contract. !When the stiffness is specified, the m

44、aterial should be tested by the method of Clause 11 in IEC 60371-2.“6.8 Electric strength!When tested by the method of Clause 16 of IEC 60371-2 with electrodes according to 4.1.2 of IEC 60243-1, the electric strength shall be not less than 50 kV/mm.“6.9 Tensile strengthTypeDescriptive codePET film s
