摘要
在恒温恒湿室的环境下,测量不同温度下电线电缆绝缘材料的抗张强度值,通过数据对比和计算,得到抗张强度试验温度的合理范围,并计算得出抗张强度换算成25℃时的计算公式和温度校正系数值。
In the constant temperature and humidity room,the tensile strength of wire and cable insulation material at different temperatures is measured,and the reasonable range of tensile strength test temperature is obtained through data comparison and calculation.The reasonable range of tensile strength test temperature is obtained,and the calculation formula and temperature correction coefficient when the tensile strength is converted to 25℃are calculated.
