GB5585.1-85
The resistivity of copper and aluminum specified in this standard is consistent with the international standard IEC28 (1925) The "International Standard for Copper Resistors" is consistent with the provisions of IEC105 (1958) "Industrial Pure Aluminum Busbar Material Standard". The specifications and dimensions specified in this standard are determined according to GB321-80 "Priority Number and Priority Number System". The unit N/mm2 is used in this standard. If a tensile machine calibrated in kg or kgf units is used in the test, the measurement results must be multiplied by 9.80665 and compiled in accordance with GB1.1-81 "General Provisions for Standardization Work Guidelines" 》Number rounding rules are rounded to three significant figures.
1 Scope of application
1.1 This standard applies to busbars for electricians.
1.2 busbars can be used for winding wire conductors.
