Wires for railway vehicles and trolley-busses are designed for internal and external wiring of railway vehicles and trolley-busses.
Wire models and their definitions shall correspond to the details given in the table below:
| Model | Definition | Primary operation area |
| ППСВ | Wire with polyvinylchloride (PVC) insulation for railway vehicles | Hardwiring and limited-mobility mounting under exposure to lubricant oils and diesel fuel |
| ППСВВМ | Wire with polyvinylchloride (PVC) insulation in PVC sheath for railway vehicles | Limited-mobility mounting, movable pantograph connection, hardwiring under exposure to lubricant oils and diesel fuel |
| ППСТВМ | Wire withthermoelastoplast (TEP) insulation in PVC sheath for railway vehicles | Limited-mobility mounting, movable pantograph connection, hardwiring under exposure to lubricant oils and diesel fuel |
| ППСТВМнг(А) | Wire withTEP insulation in PVC sheath for railway vehicles | Limited-mobility mounting, movable pantograph connection, hardwiring under exposure to lubricant oils and diesel fuel |
