        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a2°,H50mm时不超过2mma2°,H50时不超过3mm

            Straightness of the two base is not more than 2mm per 1m when a2°,H50 and 3mm when a2°,H50.

        2)硬度Hardness

        梯形铜排表面硬度为HB80105,银铜合金排表面硬度为HB85105

        The surface hardnss of trapezoidal bus bar is HB80105,and copper alloys is HB85105.
