12、land Committee EL-003, Electric Wires and Cables, to supersede AS/NZS 1972:2002. The objective of this Standard is to specify the construction, dimensions and tests for cables used underground in coal mines, excluding reeling and trailing cables. The Standard applies to cables and flexible cables in
13、tended for underground use in coal mines, but does not apply to reeling and trailing cables, which are covered by AS/NZS 1802, Electric cables Reeling and trailingFor underground coal mining purposes, cables for use in intrinsically safe (IS) circuits and data, communication and control cables not s
14、pecifically covered by this Standard. This Standard includes requirements for cables intended for fixed apparatus (e.g. power, lighting and control circuitry); impregnated paper insulated and polymeric insulated power cables for use at working voltages of 1.9/3.3 (3.6) kV up to and including 19/33 (
15、36) kV; feeder cables for connecting equipment to substations; cables for both the internal and external wiring on machines and mine shaft winder cables. These cables may be used in other applications where a risk assessment has been carried out to establish their suitability. In each case, the requ
16、irements are supplementary to those in other Australian/New Zealand Standards for cables and flexible cords. These extra requirements are necessary to meet the more onerous conditions existing for cables used in underground coal mines. This Standard is required to be used in conjunction with the req
17、uirements of the regulatory authorities administering regulations for the use of electricity in underground coal mines. The need for new or modified cables will be addressed when the situation arises. This Standard differs from the 2002 edition as follows: (a) An additional type of machine cable, Ty
18、pe 2S.3, with a voltage designation of 3.3/3.3 kV has been introduced into Section 5. (b) The voltage designation of Type 1, 2, 2S, 3, 3S, 7, 7S and 8 machine cables has been changed from 0.6/1 (1.2) kV to 1.1/1.1 kV. (c) A new a.c. high voltage test has been included for cables designated as 1.1/1.
19、1 kV in order to demonstrate that these cables are able to withstand 1.1/1.1 kV conditions. (d) As AS 1979 has been withdrawn, relevant content from this Standard has been incorporated into Section 6. (e) Appropriate cable diameters have been deleted from the tables of dimensions in Appendix C. (f)
20、Appendix D, covering machine cables with critical overall diameters, has been deleted. The terms normative and informative have been used in this Standard to define the application of the appendix to which they apply. A normative appendix is an integral part of a Standard, whereas an informative app
21、endix is only for information and guidance.

The transmission medium may be either metallic (conductors) or optical fibres. 1.4.2 Electrically symmetrical A cable in
41、which the cable cores are arranged in a geometrically symmetrical pattern to reduce as far as possible the effects of induced voltage, when the cable is carrying an alternating current.

43、passes through the midpoints of the laid-up cores, screen wires or the like. 1.4.5 Shall Indicates that a statement is mandatory. 1.4.6 Should Indicates a recommendation. 1.4.7 Support member A steel alloy or galvanized steel flexible support wire rope or non-metallic support material. 1.4.8 Suspend
44、ed length That length of cable measured from the midpoint of the bottom loop to the furthermost point of cable effective support. 1.4.9 Voltage designation For cables for a.c. systems, the rated voltages U0, U and Um expressed in the form U0/U (Um), or for cables d.c. systems, rated voltage U0 where
45、 U0 = the r.m.s. power frequency voltage to earth of the supply system or d.c. voltage of the supply system for which the cable is designed. U = the r.m.s. power frequency voltage between phases of the supply system and for which the cable is designed. Um = the maximum r.m.s. power frequency voltage
46、 between any two phase conductors for which cables and accessories are designed. It is the highest voltage that can be sustained under normal operating conditions at any time and at any point in a system. It excludes voltage variations due to fault conditions and sudden disconnection of large loads.

48、us, e.g. conveyor motors and fixed lighting. These cables are generally not required to flex or bend in service and are typically installed as fixed cables on the roof or rib in the mine and utilize the screen or armour as the earth conductor. They may be required to support several metres of their
49、own weight. The presence of acidic or alkaline groundwater in the mine environment and the potential presence of hydraulic oil, grease and other substances requires that the outer sheath of these cables be resistant to chemical attack. The cables would generally not be installed in face areas in the mine and are intended for use in applications where they are not frequently moved. Double-wire armoured cables are normally used for single anchor point suspension applications. These cables are suitable for use outside a
