GB/T 19215.1-2003 in English

《GB/T 19215.1-2003电气安装用电缆槽管系统 第1部分:通用要求》由TC67（全国电器附件标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准规定了为电气装置的导体、电缆、软线／或其他电气设备特设的，并在必要之处将它们隔离开的电缆槽和电缆管系统的要求。

1 Scope

This part specifies requirements for cable trunking and cable ducting systems intended for the accommodation, and where necessary for the segregation, of conductors, cables or cords and/or other electrical equipment in electrical installations.

This part does not apply to conduit, cable tray or cable ladder (cable bridge) or current-carrying parts within the system.

Note: There are many different designs of systems (see annex A) for which a Part 2 is under consideration.
