If the umbrella skirt distance is designed to be small, the creepage distance can be reduced under high voltage, so that the insulating support is conducted, and safety accidents are caused.

(b) Because the insulating support device needs to meet the requirements of multiple high-voltage electric shocks and even can still ensure good insulating property to high voltage after multiple lightning electric shocks, the minimum thickness of the umbrella skirt needs to meet the requirements of repeated high voltage resistance and no breakdown. This differs depending on the insulating material. The minimum thickness of the SMC used herein is not less than 5 mm. The thickness of the silicone gel will be relatively small.

In fig. 9, the conductive rails are symmetrically arranged on both sides of the main walking rail, so that a single-carbon sliding plate current collector can be used, the symmetric current collection of the vehicle body can be ensured, and the material is saved.

Alternatively, as shown by the dotted line position in fig. 9, the insulating support device on one side may be disposed at the dotted line position in fig. 9, so that the conductive rails may be disposed up and down on both sides of the main traveling rail, and at this time, a dual-carbon sled current collector needs to be used, where the two carbon sleds are respectively connected to the positive rail and the negative rail.
