This Standard replaces “Insulated cables (wires) for railway vehicles of rated voltages up to and including 3kV General” (GB 12528.1-1990) and “Insulated cables (wires) for railway vehicles of rated voltages up to and including 3kV Amendment 1. Cross-linked polyolefin insulated cables (wires) for railway vehicles” (GB 12528.11-2003). The major changes BETWEEN this Standard AND GB 12528.1-1990 and GB 12528.11-2003 are as follows. — “Insulated cables (wires) for railway vehicles of rated voltages up to and including 3kV General” (GB 12528.1-1990) and “Insulated cables (wires) for railway vehicles of rated voltages up to and including 3kV Amendment 1. Cross-linked polyolefin insulated cables (wires) for railway vehicles” (GB 12528.11-2003) are changed into “Rail vehicle cables with rated voltages up to and including 3kV” in this edition. — Update and add normative references (The Chapter 2 in GB 12528.1-1990 and GB 12528.11-2003; the Chapter 2 in this edition). — For insulation and sheathing materials, this edition specifies chlorosulfonated polyethylene rubber compound or other equivalent synthetic elastomers, ethylene propylene rubber compound, cross-linked polyolefin compound and polyolefin compound used for thin-wall cables. Delete the provisions (3.2 in GB12528.1-1990; and 4.2 in this edition) of natural styrene butadienerubber, polyvinyl chloride, neoprene, nylon and other compounds in standard GB 12528.1-1990. — The oil resistance property is divided into three classes, namely Class I, Class II, and Class III. The application environment polluted by high concentration acids and bases are not specified. Specify the cable products with Class I and Class II oil resistance property (3.2.1.5 in GB 12528.1-1990, 3.4 in GB 12528.11-2003 and 4.4 in this edition). — Specify the cable’s voltage grade in four categories. 500V, 750V, 1.5kV and 3kV. Delete the 250V grade and 1kV grade (5.4.4.1 in GB12528.1-1990, 3.1 in GB 12528.11-2003 and 5.1 in this edition). — Adjust the cable’s bending radius (3.5 in GB 12528.11-2003, and 5.4 in this edition). — Add Category 2 conductor, represented by (C). Delete the provisions for conductor structure (5.1.1 in GB 12528.1-1990, 5.1.2 in GB 12528.11-2003, and 7.1.2 in this edition). — Add the experimental value of direct voltage to the spark test voltage (5.2.3 in GB 12528.1-1990, 5.2.3 in GB 12528.11-2003, and 7.2.4 in this edition). — The thinnest thickness of thin-wall cable’s insulation has been changed from 90%-0.1mm of nominal thickness value in GB 12528.11-2003 to 75% of nominal thickness value (Table 2 in GB 12528.11-2003 and Table 11 in this edition). — The low-smoke zero halogen flame retardant cables shall pass the bunch combustion experiment, in addition to the single vertical combustion. (5.3 in GB 12528.11-2003 and 7.4 in this edition); — Insulation resistance has been changed from 1X1013Ω•m in GB 12528.11-2003 to 5X1012Ω•m in this edition. — Delete the experimental method of tin layer in tinned copper wires in Annex A. Add abrasion experiment in Annex A (Annex A in GB 12528.1-1990, Annex A in this edition). — The maxim current leakage indicator which reflects the cable’s surface resistance value is consistent with the specified value of EN50264 (Annex D in GB 12528.1-1990; Table 6 in GB 12528.11-2003, and Annex D in this edition). The Annexes A, B, C, D and E of this Standard are normative. This Standard was proposed by China Electrical Equipment Industrial Association. This Standard shall be centralized by National Technical Committee on Wire and Cable of Standardization of China SAC/TC 213. Drafting organization of this Standard.
