The invention discloses a high-
voltage power cable for a
rail transit vehicle and a technological process of the high-
voltage power cable for the
rail transit vehicle. The high-
voltage power cable comprises soft tinned conductors, a semiconductive conductor shielding layer, an ultra-clean
ethylene-propylene rubber insulating layer, a semiconductive insulating shielding layer, a
metal shielding layer, an isolation jacket, an
interlocking armor layer and a protective jacket. The soft tinned conductors are used for
electric energy transmission and are sequentially sleeved with the semiconductive conductor shielding layer, the ultra-clean
ethylene-propylene rubber insulating layer, the semiconductive insulating shielding layer, the
metal shielding layer, the isolation jacket, the
interlocking armor layer and the protective jacket. By means of the high-voltage power cable, the condition that when high-power and large-
current electric energy transmission or supplying is needed in use of power cables for the
rail transit vehicle, the multiple existing cables, meeting the related standards, for the rail transit vehicle have to be used in a parallel-connection mode is avoided, and the potential safety hazards that when any cable is broken, power supply is unstable, and even breakdown of a power supply
system occurs are avoided.
