梯形排表示方法:T/H/a

高度H标称值推荐如下H recommended:

10,11.2,12.5,14,16,18,20,22.4,25,28,31.5,35.5,40,45,50,56,63,71,80,90,100,112,125,132,140,150mm。

梯形排截面尺寸范围Cross-section:

T≤24、H≤150、H/t≤50

三、产品性能Product performance:

1)扭度Distortion

500mm长度内侧面扭度不超过2.5mm。

Not more than 2.5mm per 500mm.

3)直度Straightness

两底边在1m长的直度a>2°,H<50mm时不超过2mm,a≤2°,H≥50时不超过3mm。

    Straightness of the two base is not more than 2mm per 1m when a>2°,H<50 and 3mm when a≤2°,H≥50.

2)硬度Hardness

梯形铜排表面硬度为HB80~105,银铜合金排表面硬度为HB85~105。

The surface hardnss of trapezoidal bus bar is HB80~105,and copper alloys is HB85~105.
