The device is applicable to the distribution system of power station, petroleum, chemical engineering, metallurgy, weaving and tall building industriesetc. In the places with high automaticity and need computer to joint, such as large-scale power station and petrochemical industry system etc, it is the low voltage complete distribution device used in the generating and power supply system with three-phase AC50(60)Hz, rated working voltage 380V, rated current 4000A and below for distribution, motor central control and reactive power compensation.
Design Feature
1. Main framework adopts 8MF bar steel. Both sides of bar steel is installed with φ9.2mm mounting hole with modulus 20mm and 100mm. Inner installation is flexible and easy.
2. Two types of assembly form design for main framework, full assembly structure and partial (side frame and cross rail) welding structure for user selection.
3. Each function compartment of device is separated mutually. The compartments are divided into function unit compartment, bus bar compartment and cable compartment. Each one hasrelative independent function.
4. Horizontal bus bar adopts cabinet back level placed array pattern for enhancing the capacity of resisting electrodynamic force for bus bar. It is the basic measure for obtaining highshort circuitstrength capacity for main circuit.
5. Cable compartment design makes cable outlet and inlet up and down convenient.

1. Commercial Complexes & High-Rise Residential
Modern commercial complexes and high-rise residential buildings require reliable, compact, and fire-safe power distribution equipment.
2. Industrial Parks & Heavy Manufacturing
Industrial parks and heavy manufacturing facilities, including steel mills, cement plants, chemical factories, and automotive assembly lines, consume large volumes of medium-voltage power and require robust, outdoor-rated distribution equipment.
3. PV & Energy Storage Grid Connection
Solar photovoltaic farms and battery energy storage systems (BESS) require dedicated step-up transformer solutions to interface with the medium-voltage grid.
4. Infrastructure — Rail Transit, Healthcare & Data Centers
Critical infrastructure applications, including metro and railway systems, hospitals, and data centers, demand the highest levels of power reliability and redundancy.
5. Municipal & Environmental — Water Treatment & Pumping Stations
Municipal water supply, wastewater treatment plants, and flood control pumping stations present challenging operating conditions for electrical distribution equipment.
Use Environmental Conditions
1. Ambient air temperature: -5℃ ~+40℃ and the average temperature should not exceed +35℃ in 24h.
2. Relative humidity should not exceed 50% at max temperature. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20℃ . But in view of the temperature change, it is possible that moderate dews will produce casually.
3. Altitude above sea level should not exceed 2000M.
4. Installation gradient not exceed 5° .
5. Indoor without dust, corrosive gas and rain water attack.
