The series has three groups describing: 1) Winding wires Test methods (IEC 60851); 2) Specificatio

26、ns for particular types of winding wires (IEC 60317); 3) Packaging of winding wires (IEC 60264). BS EN 60317-27:2014 6 60317-27 IEC:2013 SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 27: Paper tape covered rectangular copper wire 1 Scope This part of IEC 60317 specifies the requirements

27、of paper tape covered rectangular copper winding wires. This covering consists of two or more layers of paper tape, all in the same direction and is primarily intended for winding coils for oil immersed transformers. The range of nominal conductor dimensions covered by this standard is: width: min.

28、2,0 mm max. 16,0 mm; thickness: min. 0,80 mm max. 5,60 mm. The paper tapes covered by this standard are restricted to those specified in IEC 60554-1 having thicknesses in the range 25 m to 125 m inclusive. 2 Normative references The following documents, in whole or in part, are normatively reference

The paper covering shall be of one or more t

35、apes wrapped firmly, closely, evenly, and continuously around the conductor. No bonding or adhesive material shall be used except to anchor the ends of paper tapes. 4 Dimensions 4.1 Conductor dimensions Subclause 4.1 of IEC 60317-0-2: 2013 applies. 4.2 Tolerance on conductor dimensions Subclause 4.2

36、 of IEC 60317-0-2: 2013 applies. 4.3 Rounding of corners Subclause 4.3 of IEC 60317-0-2: 2013 applies. 4.4 Increase in dimensions due to paper tape covering The increase in width or thickness due to the paper tape covering shall be agreed between purchaser and supplier and the minus tolerance shall

37、not exceed the values given in Table 1. The increase in width due to the paper covering shall be equal to or less than the increase in thickness. The maximum increase may be exceeded, provided that the maximum overall dimension does not exceed the sum of the maximum dimensions of the conductor plus

38、the maximum increase given in Table 1.

NOTE When the value of the proof stress of the copper is specified between minimum and maximum limits, the requirements are agreed upon between the purchaser and supplier. The description of the term “proof stress” and the method of de

41、termination are given in Annex A. 7 Springiness Test appropriate but no requirements specified. 8 Flexibility and adherence Because of the great variation in the number and the thickness of papers applied, the requirements for flexibility shall be agreed between purchaser and supplier at the time of

42、 placing the order. 9 Heat shock Test inappropriate. 10 Cut-through Test inappropriate.

BS EN 60317-27:2014 10 60317-27 IEC:2013 30 Packaging The kind of packaging may influence certain properties of the wire, for example flexibility and adherence. Therefore th

45、e kind of packaging, for example the type of spool, shall be agreed between purchaser and supplier. The wire shall be evenly and compactly wound on spools. Where wires are delivered in coils, the dimensions and the maximum masses of such coils shall be agreed between purchaser and supplier. Any addi

46、tional protection for coils shall also be agreed between purchaser and supplier. A clearance of at least 25 mm shall be arranged between the outermost layer and the periphery of the spool flange. Where there is a requirement for a protective paper between the layers and between the wire and the spoo

47、l, this shall be agreed between the purchaser and the supplier. Marking of the label when there is more than one length, identification of the separate lengths and identification of joints shall also be by agreement between the purchaser and supplier. BS EN 60317-27:201460317-27 IEC:2013 11 Annex A

48、(informative) Method of determination of x % proof stress: Rpx Proof stress is the stress (load divided by the original area of cross-section of a test piece) which is just sufficient to produce, under increasing load, a non-proportional elongation equal to a specified percentage x of the original g

49、auge length. In specifying or describing a proof stress the percentage should be quoted: the most usual example is 0,2 % proof stress (Rp0,2) expressed in megapascals (1 MPa = 1 N/mm2). The proof stress is determined from the load-elongation curve by drawing a line parallel to the straight portion of the curve and distant from it by an amount representing the required non-proportional elongation, thus determining the load at which the line cuts the curve (see Fi
