3. Main Features

1. High Integration & Compact Structure

   Independent layout of three compartments (HV, transformer and LV), small overall volume and small footprint. It can be directly placed near the load center, greatly reducing line loss.

2. Factory Prefabrication & Ready-to-Use

   All assembly and commissioning are completed in the factory, with minimal on-site construction work, short installation cycle and quick power-on, significantly shortening the project period.

3. Safe, Reliable & Strong Protection

   Equipped with complete five-prevention interlock, overload, short-circuit, leakage and lightning protection. The enclosure is rainproof, dustproof, anti-corrosion and sun-proof, enabling long-term stable operation outdoors.

4. Energy-Saving, Low-Noise & Stable Operation

   Configurable with low-loss energy-saving transformers, featuring low loss, low noise and high energy efficiency, which is more economical for long-term use.

5. Maintenance-Free & Convenient Operation

   The equipment has good sealing performance, moisture-proof and anti-pollution, basically maintenance-free in daily use; the operation space is reasonable, easy for maintenance, and supports intelligent monitoring and unattended operation.

6. Flexible, Universal & Strong Expandability

   The circuit, capacity and functions can be flexibly configured according to on-site needs, and it is very convenient to move, relocate and expand.

4. Application Scenarios
