Product Advantages

1.Strong adaptability to the ring network: supporting "one in, multiple out" and "multiple in, multiple out" wiring, compatible with the urban distribution network ring network power supply mode, ensuring fast switching of circuits in case of power outage;

2.Reliable safety protection: Fully enclosed cabinet with five prevention interlocking reduces the impact of external dust and water vapor, and increases the safety of medium voltage operation and maintenance by 40%;

3.Small footprint: Compact design (conventional size 1.2m × 0.8m × 2.2m), occupying only 70% of the space of traditional switchgear, suitable for limited space scenarios in distribution rooms;

4.Low operation and maintenance costs: Fixed structures have fewer fault points, with an average annual maintenance frequency of only 1-2 times, reducing operation and maintenance costs by 25% compared to removable cabinets;

Application Scenarios

1.Urban medium voltage ring network: As a 10kV (approximately 12kV) urban distribution network ring network cabinet, it connects different substation lines to achieve "hand-in-hand" power supply, improving the reliability of residential and commercial electricity consumption;

2.Industrial Park Power Distribution: The medium voltage distribution branch within the park distributes the power grid to the distribution rooms of each factory building, adapting to the dispersed electricity needs of park enterprises;

3.Commercial complex/large community: As a 10kV incoming cabinet and branch cabinet for the project, it controls the distribution of high-voltage electrical energy to transformers in each building, ensuring stable power supply for commercial and residential areas;

4.Distributed new energy grid connection: 10kV grid connected cabinets for distributed photovoltaic and small-scale wind power projects, adapted to the decentralized grid connection needs of green electricity, ensuring the safe integration of new energy into the distribution network.
