30、 MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover the shielded and nonshielded medium-voltage power cables that are described in Tables 1.1 (single-conductor) and 1.2 (multiple-conductor). Multiple-conductor
31、 cables may include one or more individually jacketed non-conductive optical-ber members. These electrical and hybrid electrical and optical-ber cables are for use (optical and electrical functions associated in the case of a hybrid cable) in accordance with Article 328 and other applicable parts of
32、 the National Electrical Code (NEC), ANSI/NFPA 70. 1.1 revised September 19, 2007 1.2 These cables have one or more stranded copper or aluminum conductors that are insulated with a solid, extruded dielectric. Cables that have a metal sheath or interlocked armor incorporate an effective grounding pat
33、h. A grounding conductor is optional in other cables. Cables for direct burial are so marked and have an overall covering (see 1.4 for direct-burial cables that are not covered). Cables that are for use in cable trays generally are so marked (see 62.1 and 62.2). Cables that are sunlight-resistant ge
34、nerally are so marked (see 64.1 64.3). Cables that are marked “MV-90” or “MV-90 dry” have a maximum operating temperature of 90C (194F). Cables that are marked “MV-105” have a maximum operating temperature of 105C (221F) for use where design conditions require a maximum conductor temperature above 9
35、0C (194F). Cables that are marked “dry” have insulation for use only in dry locations. All other cables have insulation that is for use in both wet and dry locations. Multiple-conductor cables that include one or more optical-ber members are surface marked to so indicate. Cables that are marked “oil
36、 resistant II” are for exposure to mineral oil at temperatures not in excess of 75C (167F). Cables that are marked “oil resistant I” are for exposure to mineral oil at temperatures not in excess of 60C (140F). 1.3 A multiple-conductor Type MV cable that has a smooth (other than lead) or corrugated m
37、etal sheath or that has interlocked metal armor may be marked for use also as Type MC cable. 1.4 This standard does not include requirements for cables with concentric neutral conductors. However, it is possible to have a single-conductor cable with a concentric neutral conductor manufactured in acc
38、ordance with the requirements of other standards, that meets the requirements for jacketed single-conductor shielded cable in this standard.
