摘　　要：通过对高落差敷设的高压交联聚乙烯(XLPE)绝缘皱纹铝护套电力电缆受力分析,设计了试验方案,对110 kV和220 kV等级的不同截面的电缆进行试验,验证电缆在运行中,缆芯与铝护套之间不存在位移。The test program was made by analyzing the forces acting on the insulated conductors in HV XLPE insulated corrugated aluminium sheathed power cables installed with high drop. Test was made respectively on 110 kV and 220 kV cables with different sizes. The result shows that during the cable operation, there is no displacement between the insulated conductors and the aluminium sheath.
