GB 12528.11-2003Insulated cables (wires) for railway vehicles of rated voltages up to and including 3 kV Amendment 1: Cross-linked polyolefin insulated cables (wires) for railway vehicles (English PDF)

Foreword

This Amendment is the supplement to GB 12528.1-1990 Insulated cables (wires) for

railway vehicles of rated voltages up to and including 3 kV -- Part 1. General rules. It is

used to supplement the provisions related to the cross-linked polyolefin insulated cables

(wires) for railway vehicles that are not covered in GB 12528.1-1990.

This Amendment shall be under the jurisdiction of the National Electric Wire Electric Cable

Standardization Committee.

The drafting organizations of this Amendment. Shanghai Nan Yang Electrical Appliance

Co., Ltd., and Tianjin Jinshan Wire & Cable Co., Ltd.

1 Scope

This document specifies the models, specifications, technical requirements and test

methods, marks and packaging of the cross-linked polyolefin insulated cables (wires) for

railway vehicles of rated voltages up to and including 3 kV.

This document applies to the cables for various vehicles of rated voltages up to and

including 3 kV and the electric equipment used in the power distribution system, control

system and signal system of the urban railway vehicles. It is especially applicable to

narrow-space and places where require low smoke, halogen-free or flame retardant.
