Double-function section insulator for rigid catenary, has jumper cable that extends to conductive rails, conducts wire of insulator, when electric power supply to pantograph is to be maintained

摘要

The insulator has a pair of conductive rails (2) having a central shoe (1) placed along the direction of catenary, a pair of arc-extinguishing wires (9) and multiple bars (8) arranged on the central shoe. A jumper cable that extends to the conductive rails, conducts the wire of the insulator, when the electric power supply to the pantograph is to be maintained.
