GB/T 5585.2-2018Copper or aluminium and its alloy bus bars for electrical purposes—Part 2: Aluminium and aluminium alloy bus bars (English PDF)

Foreword

GB/T 5585 "Copper or aluminium and its alloy bus bars for electrical purposes" consists of two parts:

- Part 1: Copper and copper alloy bus bars;

- Part 2: Aluminium and aluminium alloy bus bars.

This Part is Part 2 of GB/T 5585.

This Part is drafted in accordance with the rules given in GB/T 1.1-2009.

This Part replaces GB/T 5585.2-2005 "Copper or aluminium and its alloy bus bars for electrical purposes - Part 2: Aluminium and aluminium alloy bus bars".

Compared with GB/T 5585.2-2005, the main technical changes are as follows:

- UPDATE the normative references (see Clause 2 of this Part, Clause 2 of 2005 edition);

- SPECIFY the code and product representation method (see 4.1 and 4.2 of this Part, 3.2 and 3.3 of 2005 edition);

- MODIFY the chemical composition of aluminium and aluminium alloy bus bars (see 5.3 of this Part, 4.3 of 2005 edition);

- ADD a note to "Table 2 -- Specifications of aluminium and aluminium alloy bus bars" (see Table 2 of this Part, Table 1 of 2005 edition);

- SPECIFY the expression of test classification (see 8.1 of this Part, 7.1 of 2005 edition);

- MODIFY the expression of marking (see 9.3 of this Part, 8.3 of 2005 edition).

1 Scope

This Part of GB/T 5585 specifies the code and product representation method, technical requirements, tests, delivery length and weight, acceptance rules, product certificate and packaging, marking, transportation and storage of aluminium and aluminium alloy bus bars for electrical purposes.

This Part applies to aluminium and aluminium alloy bus bars (also known as aluminium and aluminium alloy bars) for electrical purposes.

5 Technical requirements

For the chemical composition of aluminum alloy bus bars, it may have other chemical elements with suitable contents besides the main element aluminum, including silicon, magnesium, iron, etc., but the mechanical and electrical properties of the aluminum alloy bus bars shall comply with the provisions of this Part.

NOTE: When the factory-exit inspection items of finished aluminum and aluminum alloy bus bars are all qualified, the chemical composition of the bus bars may not be used as an inspection index. If the demand party has special requirements for chemical composition, it can be specified in the order contract.
