GB/T 34130.1-2017Power-track systems -- Part 1: General requirements (English PDF)

1 Scope

1.1 This Part of GB/T 34130 specifies general requirements and tests for powertrack (PT) systems.

This Part applies to powertrack (PT) systems with a rated voltage not exceeding

277 V a.c. single phase, or 480 V a.c. two or three phase 50 Hz or 60 Hz with a rated current not exceeding 63 A. These systems are used for distributing electricity in household, commercial, or industrial premises.

1.2 Powertrack systems, according to this Part, are intended for use under the following conditions:

- an ambient temperature in the range -5 °C~+40 °C, the average value over a 24 h period not exceeding 35 °C;

- a situation not subject to a source of heat likely to raise temperatures above the limits specified above;

- an altitude not exceeding 2000 m above sea level;

- an atmosphere not subject to excessive pollution by smoke, chemical fumes, prolonged periods of high humidity or other abnormal conditions.

In locations where special conditions prevail, as in ships, vehicles and the like and in hazardous locations, for instance, where explosions are liable to occur, special constructions may be necessary.

This Part does not apply to:

- cable trunking systems and cable ducting systems covered by GB/T 19215;

- busbar trunking systems covered by GB 7251.2;

- electrical supply track systems for luminaires covered by GB/T 13961.
