Steel Slip Line and Low Resistance Slip Line Product Features:

This product consists of a ladder-type copper rod and channel steel or a "T"-type copper row and a grooved aluminum combined phase. High-strength special insulators are used as supports to form mobile trolley wires for feeding various crane equipment. This product has the following features:

1, reliable operation, no power interruption failure.

2, can be used for high temperature, high dust, high corrosion gas and other harsh environments.

3, mechanical strength, not easy to bend and deformation, can withstand a strong short circuit impulse current.

4, according to user needs to set the ampacity, up to 3000A or more, the voltage level can reach 5KV or more.

5, the use of copper or copper aluminum conductor, can greatly reduce the power loss of the wire.

6. After adding an auxiliary cable, a low-impedance trolley wire can be formed and the wire resistance can be reduced several times.

7, the wiring can be in the upper or lower slide.

8, JGH-"I" type trolley wire is more radiating surface, compact structure, easy installation and maintenance.
