摘要
参考国内外相关标准,根据电力电缆金属屏蔽的热稳定性能,对中压电力电缆的金属屏蔽层截面积提出明确的要求,以规范招投标技术要求,保证电力电缆金属屏蔽满足电网长期稳定安全运行要求。
According to national and international standards, this paper specifies the cross-section sizes of metallic screen of power cable so that it meets with the thermal short-circuit requirements. It ensures that the metallic screen meet the requirements for long-term safe operation of power distribution systems. The conclusion is part of technical specifications for tender documents.
