Electrification railway uses electric locomotive as its power which is provided by electric traction power supply system composed of traction substation and catenary. After the power from the power plant is transformed by the traction substation, it sends power to the overhead catenary over the railway, while the electric locomotive takes power from the overheadcatenary to drive the electric locomotive forward. To construct an electrification railway, many traction substations will be built along the line. A traction substation will be built every 60kmfor a single track railway, while every 40km for a double one. We provide comprehensive cable connection solutions for such power supply system of electrification railway.
Cable connection catenary power supply in traction substation
 | Connection of high voltage cable to overhead line and transformer bushing ① We provide 110kV outdoor termination to connect high-voltage overhead lines to transformer bushings ② We provide 110kV GIS termination to connect transformer to inner cone bushing.  |
Cable docking, branching andswitching | Connection between cable andelectrical equipmentwith inner cone or outer cone bushing | Sheath overvoltage protectionfor cable connection system of electrification railway | Insulation enhancement protectionfrom flashover, power failure and incorrect operation of railway traction power supply system | |||

UELC overhead line insulation products provide enhanced insulation protection for messenger wires, suspension wires and other related conductors |
 | Overhead line covers are used to effectively insulate conductors from risk of short-circuit accidents that may caused by reduced safety distance of the catenary system when messenger wires, suspension wire or other relevant conductors are accidentally contacted by trees, birds, wildlife, plants or even sabotage, or when they cross trees, buildings, tunnels, bridges, rivers, and ponds. | |
UETP and UESC insulation covers combined with UELC provide protection for catenary, suspension wire areas and junctions | ||
