1. Integrated Design: Integrates high-voltage switches, transformers, low-voltage power distribution and protection devices into one, no need to build a separate power distribution room, small floor area, saving civil engineering costs.

2. Strong High-Voltage Adaptability: Designed specifically for high-voltage power distribution scenarios, withstanding high-voltage impact, reliable insulation performance, and stable operation at 10kV～44kV high-voltage levels to meet different high-voltage power distribution needs.

3. Excellent Outdoor Adaptability: Protection class up to IP54 and above, dust-proof, rain-proof, corrosion-proof, can operate outdoors for a long time in the environment of -25℃～45℃, adapting to complex climate conditions.

4. Stable and Safe Operation: Adopts fully sealed structure (oil-immersed type), anti-oil leakage, low loss, low noise, equipped with complete protection devices, which can effectively avoid equipment failures and potential safety hazards.

5. Convenient and Efficient Installation: Direct ground installation, no complex construction, integrated structure can be quickly hoisted and commissioned, shortening the construction period and reducing installation costs.

6. High Customization Level: According to customer needs, the voltage level, capacity, cooling method, protection level and connection group can be customized to adapt to the personalized needs of different scenarios.
