The function of the electrical connection is to connect the circuits between the sections of the contact suspension power supply to ensure the smooth flow of the circuit. Parallel connection power can be achieved through the electrical connection, reducing power loss  improving power supply quality. Between electrical equipment  the contact network, electrical connection lines are used to make reliable connections, so that the equipment can fully function, avoid burnout accidents,  complete various power supply methods  maintenance needs. The electrical connection is used in places including load cables  contact lines, femoral tracts, anchor section joints, turnouts, etc.

The electrical connection wires are made of materials with good electrical conductivity. Soft copper stranded wires TRJ-95  TRJ-120 are used in the copper  copper alloy contact line sections. The selection of the wire diameter of the electrical connection line is mainly determined by the cross-sectional area of the bearing cable. When the bearing cable is 95 square millimeters  less, TRJ-95 is used for the electrical connection wire,  when the bearing cable is 120 square millimeters, TRJ-120 is used. In the steel-aluminum contact line section, LJ-150 stranded aluminum stranded wire is used. In order to reduce the hard points at the connection point between the electrical connection line  the contact line,  maintain the elasticity of the contact net, it is required that the electrical connection line be made into a helical spring shape, in order to adapt to the stretching of the trailing line force between the clues when the electrical connection line is connected. When accidentally burnt, you can also release it to continue to use, in order to save materials.
