7、ODUCTION1 Scope1.1 This Outline covers the requirements for multiple conductor cables intended for use indoors andoutdoors as vertical drop cable from a crane or hoist down to a pendant pushbutton station, or as a controlcable in a crane and hoist system in accordance with Article 610 of the Nationa

8、l Electrical Code (NEC),ANSI/NFPA 70. The wire is rated 300 or 600 Volts, and 60, 75, 90, or 105C (140, 167, 194, or 221F).2 Units of Measurement2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.3 Components3.1 Except as indica

9、ted in 3.2, a component (including gaskets and polymeric materials) of a productcovered by this outline of investigation shall comply with the requirements for that component.3.2 A component is not required to comply with a specific requirement that:a) Involves a feature or characteristic not requir

10、ed in the application of the component in theproduct covered by this outline of investigation, orb) Is superseded by a requirement in this outline of investigation.3.3 A component shall be used in accordance with its rating established for the intended conditions ofuse.3.4 Specific components are in

11、complete in construction features or restricted in performance capabilities.Such components are intended for use only under limited conditions, such as certain temperatures notexceeding specified limits, and shall be used only under those specific conditions.4 Undated References4.1 Any undated refer

12、ence to a code or standard appearing in the requirements of this outline ofinvestigation shall be interpreted as referring to the latest edition of that code or standard.AUGUST 14, 2015UL 25624UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULCO

13、NSTRUCTION5 Materials and Workmanship5.1 Only materials that are acceptable for the particular use shall be employed in a wire. Wires shall bemade and finished with the degree of uniformity and grade of workmanship that are practicable in awell-equipped factory.5.2 Each material used in a wire shall

14、 be compatible with all of the other materials used in the wire.6 General6.1 Assembly6.1.1 These constructions consist of two or more insulated conductors cabled together with optional fillersand/or binder tapes of suitable material to form a round cable. A messenger wire or wires is joined to theca

15、bled conductors by means of a web.6.2 Conductors6.2.1 Conductors shall be 18 10 AWG, stranded, soft-annealed copper with or without a continuouscoating of tin over each strand, in accordance with the Standard for Machine-Tool Wires, and Cables, UL1063.6.3 Insulation6.3.1 The thicknesses and material

16、 requirements for PVC or PVC/nylon insulation shall be the same asfor Type THHW or THHN wire in accordance with the Standard for Thermoplastic-Insulated Wires andCables, UL 83; or Type MTW wire Construction A or Construction B in accordance with the Standard forMachine-Tool Wires and Cables, UL 1063

17、 Surface marking may be omitted. The average and minimumthickness of the insulation shall be determined in accordance with the test, Thickness, in the Standard forWire and Cable Test Methods, UL 2556.6.4 Jacket6.4.1 The jacket material shall be PVC and shall meet the requirements of one of the PVC

18、jacket classesdescribed in the Standard for Flexible Cords and Cables, UL 62. The thicknesses requirements shall beas shown in Table 1. The average and minimum thickness of the jacket shall be determined in accordancewith the test, Thickness, in the Standard for Wire and Cable Test Methods, UL 2556.
