...芯高压电缆 ; 金属护套 ; 感应电压 ; 提升意义 ; 问题讨论 [gap=793]Key words: single core high voltage cable; metal sheath; induction voltage; significance of increase; discussion ..
The invention relates to a heat tracing cable with an organic insulated metalsheath and a manufacturing method thereof.
本发明涉及一种有机绝缘金属护套伴热电缆及其制造方法。
2
Once the grounding system of HV single-core cable is broken, high floating voltage will appear on its metalsheath, thus causes serious consequence.
高压单芯电缆的接地系统一旦被破坏，在其电缆金属护层上会产生高值悬浮电压而引发严重后果。
3
The earthing method of the metalsheath varies somewhat in different cable lengths, which affects greatly line parameters, especially zero sequence impedance.
