Product Overview
This series is a versatile and cost-effective three-phase distribution transformer designed for 10kV and below networks. Widely used in industrial, commercial, and residential areas, it serves as the primary component for safe and reliable conversion from medium-voltage to low-voltage (400V) consumption.

Core Advantages
- We Match Your Grid Design: Offers three standard vector groups (Dyn11, Yzn11, Yyn0). Whether your local grid requires harmonic suppression, unbalanced load capacity, or a specific grounding method, we have the right fit. No need to redesign your system.
- Versatile Voltage Input: HV side covers 6kV, 6.3kV, 10kV, and 10.5kV. Choose between ±2×2.5% or ±5% off-circuit taps to adapt to your local grid fluctuations. LV side is a standard 0.4kV output for direct end-user equipment connection.
- Ultra-Low Operating Costs: Capacity from 30 to 2500 kVA. Designed with excellent energy savings (no-load current down to 0.32%) to meet global efficiency standards. The longer it runs, the more electricity costs you save.
- Built to Last with Minimal Maintenance: The off-circuit tap-changing structure is simple and robust, meaning fewer breakdowns. The oil-immersed design provides excellent heat dissipation, making it perfect for both indoor and outdoor installations without constant babysitting.
All our 10kV distribution transformers are manufactured in strict accordance with GB 1094 and IEC 60076 standards. Full type test reports and third-party inspection certificates are available upon request.
Typical Applications
10kV distribution substations, pole-mounted transformers, and pad-mounted substations in urban and rural power grids.
Distribution rooms for various buildings such as factories, shopping malls, schools, hospitals, and residential communities.
10kV grid-connection step-up transformers for distributed generation sources like photovoltaic and wind power.
Auxiliary power supply systems for infrastructure such as railways, highways, and airports.
