With the development of urbanization, overhead lines in urban areas are commonly
transformed into the underground power cables. Since the single-circuit cables' load, which …

With the increase of urban electrical load, a continuous extending capacity reformation for
cable lines came up. Nowadays, it has been built high-voltage cables in parallel and put into …

The sheath in underground power cables serves as a layer to prevent moisture ingress into
the insulation layer and provide a path for earth return current. Nowadays, owing to the …

The number of high-voltage parallel cables is rapidly increasing. The alternating magnetic
field generated by the working current of power cable cores induces voltage in the adjacent …

There will be circulating currents in metal sheaths of cross bonding cables when length or
arrangements of three segments are different. The phasor sums of sheath-induced voltages …

The number of cables used for urban power supply increases rapidly. The sheath current in
these cables, which is generated via induction, produces a current loss. When the situation …

In power lines, the proportion of parallel cables is gradually increasing, but the uneven
current distribution and sheath circulation affect the safe and stable operation of parallel …

The breakdown accidents of cable outer sheath and sheath voltage limiters frequently occur
due to the unreasonable sheath bonding design. Unlike pure cable lines, the sheath voltage …

Power cables have been used more frequently in planning and designing the urban power
grid. With the rapid development of power grid engineering, the power grid's capacity is …

Due to asymmetrical arrangement of multi-loop high-voltage cables and unequal distance of
each section in cross-connection grounding, the induced voltage cannot be completely …
