18、814 3UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover single-conductor, 18 10 AWG, gas-tube-sign cables with temperature ratings of 105C 250C (221F 482F), and ratings of 5000 volts, 10000 volt

19、s, or 15000 volts. The cables are for use with gas-tube systems for signs, outline lighting, and interior lighting in accordance with the National Electrical Code and the Standard for Electrical Signs, UL 48. 1.2 Assemblies that include these cables and are intended for use as components of gas-tube

20、 signs shall meet the requirements in the Standard for Electric-Sign Components, UL 879. 2 References 2.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 2.2 Wherever the desi

21、gnation UL 1581 is used in this standard, reference is to be made to the designated parts of the Reference Standard for Electrical Wires, Cables, and Flexible Cords, UL 1581. Whenever the designation UL 2556 is used in this standard, reference it to be made to the designated parts of the Standard fo

22、r Wire and Cable Test Methods, UL 2556. 3 Units of Measurement 3.1 In addition to being stated in the inch/pound units that are customary in the USA, each of the requirements in this standard is also stated in units that make the requirement conveniently usable in countries employing the various met

23、ric systems (practical SI and customary). Equivalent although not necessary exactly identical results are to be expected from applying a requirement in USA or in metric terms. Equipment calibrated in metric units is to be used when a requirement is applied in metric terms. 4 Materials 4.1 Each mater

24、ial used in a cable shall be compatible with all of the other materials used in the cable. 5 Conductors 5.1 Materials, sizes, and ratings 5.1.1 The conductor shall be of soft-annealed copper. The conductor shall be 18 10 AWG in size. The conductor shall not be smaller in area than indicated in Table

25、 5.1 and shall be continuous throughout without joints in the conductor as a whole. The voltage rating of the cable shall not exceed the rating shown in Table 5.1 based on conductor size. Effective date for 5.1.1 changed from January 6, 2012 to October 1, 2012 5.1.2 The size of a conductor shall be

26、veried either by determination of the d-c resistance or by determination of the cross-sectional area as described in 5.1.4. Measurement of the d-c resistance is to be as described in the test, D-C Resistance, in UL 2556. Determination of the conductor size by measurement of the direct-current resist

27、ance is the referee method in all cases. The d-c resistance shall not be higher than the maximum indicated for the size in Table 5.3 or 5.4, as applicable.

28、ROM UL 5.1.3 The resistance of a copper conductor measured at a temperature other than 20 or 25C is to be adjusted to the resistance at 20 or 25C by means of the applicable multiplying factor found in the table titled Adjustment factors for dc resistance of conductors , in UL 2556. 5.1.4 Where measu

29、red as the means of size verication (see 5.1.2), the cross-sectional area of the conductor shall not be smaller than the minimum area indicated for the size in Table 5.1. The cross-sectional area of the conductor is to be determined as the sum of the areas of its component round strands, with the in

30、dividual strands measured as described in 5.1.5. Where the sum of the strand areas does not comply, the conductor area is to be determined by the weight method described in the test, Cross-Sectional Area by mass (weight) method, in UL 2556. The area determined by the weight method is to be taken as

31、conclusive.

It is to be assumed that any one strand is practically constant in diameter throughout its length. 5.1.6 No particular combination of the individual strands of a conductor is required; however, simple bunching (untwisted strands)

34、shall not be used. 5.1.7 The individual wires strands used in making up a conductor are usually drawn to a specied diameter that does or does not correspond to the diameter of an established gauge number. The individual strands are not required to be all of the same diameter. 5.1.8 The length of lay

35、 of the strands in every layer of a concentric-lay-stranded conductor shall be 8 16 times the outside diameter of that layer. The direction of lay of the outer layer shall be left-hand. 5.1.9 The length of lay of the strands in a single-bunch bunch-stranded conductor shall not be greater than indica

36、ted in Table 5.2. The direction of lay shall be left-hand.

43、 continuous coating of tin or other metal or alloy if the conductor is insulated with a material that is capable of corroding unprotected copper. 5.3 Separator 5.3.1 A separator between the conductor and the insulation is not required but, if provided, shall consist of a close wind or braid of mater

44、ial such as ne cotton, or a close wind or wrap of a material such as paper or cellophane. A separator shall be colored or opaque to make the separator clearly distinguishable from the conductor once the insulation is removed. The color shall be other than green or green and yellow and may be solid,

45、striped, or in some other pattern. 6 Insulation 6.1 The conductor shall be insulated or integrally insulated and jacketed for its entire length with one or more of the insulation or insulation/jacket materials for which physical-properties limits are tabulated in Specic Materials, Section 50, of UL

46、1581 or with another such material evaluated for the use. The insulation or integral insulation/jacket that is the outermost layer on GTO Cable marked integral sleeve shall be of a material that has a minimum, unaged tensile strength of 1200 lbf/in 2 or 8.27 MPa (MN/m 2 ), or 827 N/cm 2 , or 0.844 k

The insulation or integral insulation/jacket material shall have a temperature rating of 105C (221F), 150C (302F), 200C (392F), or 250C (482F), shall be applied directly to the surface of the conductor or to the separator, if one is used, and shall comply with the requirements in Sections9

48、2 1 . 6.2 The applied insulation or integral insulation and jacket shall provide a circular cross section for the insulated or insulated/jacketed conductor, and the conductor itself shall be centered in the applied material so that, when determined by the pin-gauge or optical method, the minimum thi

49、ckness at any point of the applied material is not less than 90 percent of the average thickness of the material as determined by the difference method. The average thickness of the insulation or integral insulation/jacket is not specied. 6.3 An insulation or jacket that is of material generically different from any insulation or jacket material referenced in 7.2 (new material), or that is as referenced in 6.1 or 7.2 yet does not comply with th
