| 电力电缆的交叉互联不是为了两端接地，而是实现将较长的电缆用绝缘接头分割成多多段分别接地，并且通过交叉互联在满足外护层电压要求的同时，将外护层的电流通过三相中和降到最小。 The cross interconnection of power cables is not for the purpose of grounding at both ends, but to realize the separation of long cables with insulated joints into multiple sections for separate grounding, and to minimize the current of the outer sheath through three-phase neutralization while meeting the voltage requirements of the outer sheath through the cross interconnection. |
