Indoor Electric Cabinet Distribution Low Voltage And Mv Switchgear
This product is suitable for power distribution systems of power plants, oil and chemical industry, metallurgy industry and high-rise buildings, especially in some places where requires for high automation and connection to computers such as larger power plants and petrochemical industry. It adapts to 3-phase system with frequency 50 (60) Hz, rated voltage 380V (400), (600), rated current 4000A (Max), and is used for low voltage distribution equipment of power supply system, motor control center and reactive power compensation.
a. The main structure is made of shaped steel of type 8MF with two mounting holes
(m=20mm, 100mm, and diameter=9.2mm). On both sides. It is flexible and convenient to assemble.
b. The function units are divided into three compartments: Function compartment, busbar compartment
and cable compartment, each has independent function.
c. The horizontal busbars are arranged in parallel at the back of cubicle to strength their resistance
to electric power, which is the basic measure to make main circuit have high intensity of short circuit.
d. The design of disconnected unit for cable makes it convenient for cable's use.
