electrical network(50/60Hz, voltage not higher than 660V). At the same time, they are with circuit protection like overload,
short circuit and current leakage and provide the power outlets for electrical equipments. These boxes are widly used in oil
themical, industry, metallurgy, power plants, cola mines, machinery, textile, ports, docks and other industries. Specifically
for maintenance in the tunnel range of rail transit.
