LV & HV cabinet

Product description

The switch cabinet is applied to the distribution system in the power plants, high-rise buildings, chemical industry, and petroleum, metallurgy and textile industries. In the large power plants and highly automated petroleum and chemical industries that require connecting with computers, it is used, as a complete low-voltage distribution equipment, for power distribution in the power generation and distribution system with three-phase AC frequency 50(60)Hz, 380V(400)(600) and rated current up to and including 4000A, and motor centralized-control and reactive power compensation.

IV. Main Structure The main structure adopts 8FM opening section steel, in both sides of which there are two mounting holes with modulus 20mm and 100mmφ9.2mm respectively. The internal mounting is flexible and convenient. The main structure has two alternatives of mode of assembly, i.e. fully assembled structure and the structure with welded part frames and beam. All the function chambers of the cabinet are separated. The compartments include a functional unit chamber, a bus chamber and a cable chamber. All the chambers are independent relatively. The horizontal main bus bar is arranged horizontally on the cabinet back for the purpose of enhancing the bus’s capability of resisting electromotive power. This is a basic measure to make the main circuit have a high short circuit withstand strength. The design of cable compartment enables the cables to pass through upwards or downwards to be extremely convenient.
