20、part of IEC 62011 is one of a series which deals with industrial, rigid, moulded, laminated tubes of rectangular cross-section and rods of rectangular and hexagonal cross-section based on thermosetting resins for electrical purposes. The materials are similar to those described in IEC 61212-1 but of

21、 different cross-section. This series, under the general heading Insulating materials Industrial, rigid, moulded, laminated tubes and rods of rectangular and hexagonal cross-section based on thermosetting resins for electrical purposes, consists of three parts: Part 1: Definitions, designations and

22、general requirements Part 2: Methods of test Part 3: Specifications for individual materials Page3 EN620111:2002-110261 2002:CEI 7 INSULATING MATERIALS INDUSTRIAL, RIGID, MOULDED, LAMINATED TUBES AND RODS OF RECTANGULAR AND HEXAGONAL CROSS-SECTION BASED ON THERMOSETTING RESINS FOR ELECTRICAL PURPOSE

23、S Part 1: Definitions, designations and general requirements 1 Scope This part of IEC 62011 contains the definitions and designations related to, and the general requirements to be fulfilled by, industrial, rigid, moulded, laminated tubes of rectangular cross- section and rods of rectangular and hex

24、agonal cross-section. The moulded sections are manufactured using either phenolic or epoxy resins as the binder and using the following reinforcements: cellulosic paper, cotton cloth or glass cloth. This standard covers both rods and tubes of natural colour and those containing colouring matter or o

25、ther additives. Materials which conform to this standard meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this standard

For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 472:1999, Plast

27、ics Vocabulary 3 Definitions For the purpose of this part of IEC 62011, the following definitions, which are based upon those given in ISO 472, apply. 3.1 rectangular, moulded, laminated tube (as applied to thermosets) tube formed by wrapping impregnated layers of material on a mandrel, curing the a

28、ssembly in an appropriate square or rectangular mould under heat and pressure, and then removing the mandrel NOTE The mandrel and the mould are chosen to give a moulded tube of the required dimensions. The finished moulding may be supplied in the as moulded state or machined to specific dimensions.

30、ding may be supplied in the as moulded state or machined to specific dimensions. The cross-section in the rod is of the form of a rectangle (includes square section) or a regular hexagon. 3.3 phenolic resin generic term for a class of resins made by the polycondensation of phenol, and derivatives, w

31、ith aldehydes 3.4 epoxy resin synthetic resin containing epoxide groups, formulated to enable cross-linking 3.5 cross-section shape or profile of the moulded rod or tube when this is cut at right angles to its length NOTE The dimensions of the cross-section of a rectangular rod are the distances bet

32、ween opposite faces of the cross-section and the distance between flats of a hexagonal rod is the distance between two opposite faces of the regular hexagonal cross-section. 4 Designations and abbreviations 4.1 Designations 4.1.1 Individual types are designated by: a two-letter abbreviation denoting

33、 the resin; a second two-letter abbreviation denoting the reinforcement; a serial number of two digits, the first digit denotes the form of the product 5 indicating rectangular moulded tube, 6 indicating rectangular moulded rod, and 7 indicating hexagonal moulded rod; the second digit distinguishes

34、between sub-grades of the same type. NOTE The abbreviations are given in 4.2. 4.1.2 The complete designation of the moulded tube or rod is denoted by description: rectangular moulded tube, rectangular moulded rod or hexagonal moulded rod, the number of the IEC standard, e.g. IEC 62011-3-1, the desig

35、nation of the individual type according to 4.1.1, the nominal dimensions of the tube: internal dimensions (mm) wall thickness (mm) length (mm), or the nominal dimensions of the rectangular rod: dimensions of the cross-section (mm) length (mm), or Page5 EN620111:2002-110261 2002:CEI 11 the nominal di

36、mensions of the hexagonal rod: distance between flats (mm) length (mm), a letter designating the finish on the outer surfaces of the tube ”A” designating as produced, ”B” designating machined finish.

43、pe are necessarily unsuitable for applications other than those listed for that type, or that specific tubes or rods will be suitable for all applications within the wide descriptions given. bThe number of threads in warp and weft of these woven cloths fall usually, but not necessarily, into the fol

44、lowing ranges: fine weave : more than 30 threads per centimetre; coarse weave : 18 to 30 threads per centimetre; very coarse weave : less than 18 threads per centimetre. These values are given for information only. They are not to be considered as specification requirements. In general, the finer we

45、ave materials have better machining characteristics. 5 General requirements Appearance All material in any one consignment shall have properties within the limits of this specification. Rectangular or hexagonal moulded rods and rectangular moulded tubes shall be supplied in either the “as produced“

46、condition or with a machined surface finish. Cracks are more likely to occur in thicker cross-sections, typically for rods with cross-sectional dimensions exceeding 20 mm, or for tubes with a wall thickness exceeding 10 mm or where the ratio of the wall thickness to the internal dimensions exceed 0,

47、4. All tubes and rods shall be supplied with their ends smooth and trimmed square. They shall be free from voids, holes and open cracks NOTE 1 Fine stress cracks are an inherent feature of certain types and sizes of tubes and rods, particularly with a paper base. Such cracks are more likely to occur

48、 in thicker cross-sections, typically 20 mm 2or greater for rods and tubes with a wall thickness exceeding 10 mm or where the ratio of the wall thickness to the smaller internal measurement between flats exceeds 0,4. NOTE 2 Some resin concentration is permissible in the region of the mould lines and

49、 at the centre of rods. NOTE 3 Tubes and rods may be supplied with a varnish finish by agreement between the supplier and purchaser.
