13、or underground coal mining purposes. The Standard aligns with AS/NZS 2802 Electric cablesReeling and trailingFor mining and general use (other than underground coal mining) for cables that have been developed to meet the special requirements of the Australian surface mining industry. The objective o
14、f this Standard is to specify construction and tests of reeling and trailing cables specifically designed for use in underground coal mines. Where the method of testing differs from, or has not yet been included in AS/NZS 1660, the test method has been included in Clause 25 and appendices to this St
15、andard. While the requirements of underground coal mining continue to determine the cables to be incorporated in this Standard, it is recognized that many of these cables will be equally applicable to other installations, e.g. underground metalliferous mines, ship loaders, travelling cranes, reclaim
16、ers at loading stations and other materials handling plant. Other requirements may apply in these applications. Appropriate requirements for new types and sizes will be included in this Standard as the need arises. This Standard differs from the previous edition in the following significant ways: (a
17、) Type 217 and Type 280A cables have been deleted. (b) Insulation and sheathing materials have been referenced to AS/NZS 3808. (c) The definition of voltage designation has been modified to align with AS/NZS 2802. (d) The nominal overall diameters of cables have been deleted from the tables of dimen
18、sions. Consequently Appendix D has been deleted. (e) The extruded covering on interstitial conductors of Type 240 and Type 260 cables is now termed insulation. The terms normative and informative have been used in this Standard to define the application of the appendix to which they apply. A normati
19、ve appendix is an integral part of a Standard, whereas an informative appendix is only for information and guidance. Statements expressed in mandatory terms in notes to tables are deemed to be requirements of this Standard. Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 05 Aug 2008 3 AS/NZS 1802:2003

26、ground coal mines. An essential feature of this Standard is the requirement that cables used for alternating current supply be electrically symmetrical. This Standard is intended to apply only to cables of the types provided for in the tables of construction and dimensions. This Standard also provid
27、es the basis of requirements for other sizes of cable not specified in this Standard.

32、those below apply. 3.1 Approximate value A value which is neither guaranteed nor checked. 3.2 Bunch A number of wires all of which are twisted together in the same direction and with the same length of lay throughout. 3.3 Composite screen A screen comprising stranded or bunched copper wires applied
33、in one direction and interwoven in the opposite direction with polyethylene terephthalate yarn, or its equivalent. 3.4 Conductor covering Elastomeric semiconductive material extruded over the earth conductors. 3.5 Conductor screen A layer of non-metallic semiconductive material applied directly over
34、 the conductor. 3.6 Cradle separator A shaped section of elastomeric material, designed to support the core assembly, fill the centre interstice and provide a specified separation between individual power cores. 3.7 Direction of lay The slope direction of the conductor wire, bunch, core, screen or a
35、rmour strands when the stranded conductor or cable is held vertically. It is right-hand when the slope is in the direction of the central part of the letter Z, and left-hand when the slope is in the direction of the central part of the letter S. 3.8 Earth conductor A conductor laid up in the cable f
36、or the purpose of providing earth continuity. 3.9 Fictitious diameter Diameter calculated according to a formula based only on cross-sectional area of conductor, number of cores and specified component dimensions and which ignores conductor make- up and the possibility of components having dimension
37、s other than as specified. The fictitious value is only used to determine the mechanical protective coverings of the cable, i.e. inner and outer sheath and pliable armour strand size. 3.10 Insulation screen A screen applied directly over insulation as follows: (a) A non-metallic semiconductive mater
38、ial. (b) A combination of (a) and composite screen. 3.11 Length of lay The axial length of one complete turn of the helix formed by a cable component, e.g. (a) a bunch of a multiple stranded conductor; (b) a core of a laid-up core assembly; or (c) the strands of pliable armour in a cable.

40、e layer the length of lay of bunches or strands is uniform. 3.14 Pilot/control core An insulated conductor for use in conjunction with a protection or other control system. 3.15 Pitch circle diameter The diameter of a circle which passes through the midpoints of like cable components, e.g. (a) a giv
41、en layer of bunches or strands in a multiple stranded conductor, or the laid-up cores of a multicore circular cable; or (b) the composite screen of a core or strands of pliable armour in a circular cable. 3.16 Power core A power conductor with insulation of the appropriate voltage grade including, w
42、here applicable, semiconductive and composite screens. 3.17 Reeling and trailing cable A cable having flexible conductors, insulation incorporating conductor and insulation screens where appropriate, filling, reinforcement where appropriate, one or more protective coverings, and being specially desi
43、gned to provide a flexible electrical connection between portable or mobile equipment and a point of supply. 3.18 Routine tests Tests made by the manufacturer on all completed cable to demonstrate the integrity of the cable. 3.19 Sample tests Tests made by the manufacturer on samples of completed ca
44、bles or components taken from completed cables, at a specified frequency, so as to verify that the finished product meets the design specification. 3.20 Strand An assembly of wires laid up helically in one or more layers. 3.21 Type tests Tests required to be made before supplying on a general commer
45、cial basis a type of cable covered by this Standard, to demonstrate performance characteristics to satisfy the intended application. These tests are such that after they have been made, they need not be repeated unless changes are made in the cable materials or design which might change the performa
46、nce characteristics. Accessed by UNIVERSITY OF SOUTH AUSTRALIA on 05 Aug 2008 7 AS/NZS 1802:2003 COPYRIGHT 7 4 VOLTAGE DESIGNATION Due to common usage in the mining industry, cables in this Standard have voltages designated using phase voltage/phase voltage. However, although the cables specified fo
47、r use with a.c. in this Standard are suitable in non-effectively earthed systems they are not intended for continuous operation with one phase earthed. The voltage designation takes into consideration the fact that the system voltage may vary up to 9.1 percent from the designated voltage. 5 DESIGNAT
48、ION AND APPLICATION Cables are designated by means of a type number. The type number incorporates reference to the voltage, e.g. Type 209.3 identifies Type 209 rated at 3.3/3.3 kV. Types of cables and their applications are listed in Table 1. NOTE: For the cables specified in this Standard for use i
49、n underground coal mines, the first digit of the type number is 2. For those specified in AS/NZS 2802, for use in other than underground mining, the first digit of the type number is 4. These initial numerals have been chosen so that, for cables of like construction (e.g. as in the case of Types 209 and 409), the possibility of mistaken identity is reduced even after the cable has been worn or damaged.
