Non-coal mines, tunnels and public facilities construction mobile substation is a complete set of box-type integrated substation that mounted on the sled-shaped steel chassis which is special reinforced. It is placed on the flat ground in mines or public construction site to supply power without foundation. It can be movable by tractor if necessary, operated specially for the movement condition.

European electrical control technology and fully protection functions:

The electrical control technology was imported from Europe, which has the protection of overload, short circuit, leakage, leakage lockout, overvoltage, under voltage, over temperature protection, etc.

Multiple power supply, independent protection:
According to user requirement, multiple outputs in low voltage end, independent protect for circuit.

With insulation monitoring, safety:
Adopting insulation monitoring to keep operation security.

Protection and control by microcomputer, highly intelligent:
Microcomputer centralized display and control, highly intelligent.

Special design for extraordinary circumstances:
Special design according to the movable condition, high degree of protection, high environment adaptability.

Special cable connectors and convenient to use:
Independent cable boxes or fast plug connectors, convenient to wiring.
