FEATURES

>> Product Introduction

The 10kV three-phase oil-immersed distribution transformer is a critical component in power distribution networks and industrial power systems. Featuring a compact design with aesthetic appearance, it offers low noise operation and excellent overload capacity. Available in hermetically sealed or conservator tank types, this transformer is ideal for various applications including plants, mines, petrochemical facilities, and agricultural power systems. Its robust construction ensures reliable performance even in environments with oil contamination or chemical exposure. With high efficiency and durable design, it provides stable voltage transformation from 10kV to low-voltage levels, making it an essential solution for modern power distribution requirements.

Product Advantage

1. Precise Voltage Regulation & Step-Down Performance

Our 10kV oil-immersed transformer delivers exceptional voltage regulation (±2.5% tolerance), efficiently stepping down high voltage (10kV) to safe low voltage (400V) levels. With 98.5% efficiency rating (per IEC 60076), it minimizes energy waste while ensuring stable power for residential, commercial, and industrial applications.

2. Enhanced Electrical Isolation

The transformer provides complete galvanic isolation between primary and secondary windings, protecting end-user equipment from voltage surges (withstands up to 95kV impulse voltage).

3. Safety to electrical appliances

High voltage power supply and fluctuation in voltage are the major reasons for the occurrence of electrical shocks and electrical hazards. It can cause short circuits, damage to electrical appliances, damage to property and life, and fire. The distribution transformers help in supplying consistent and safe voltage for the functioning of electrical appliances. It minimizes the risk of electrical hazards and offers safety to both appliances and life.

4. Energy Loss Reduction Technology

Incorporates low-loss design (no-load losses <0.8%, load losses <1.2%) with optimized magnetic flux distribution. Reduces transmission waste by up to 40% compared to conventional models, verified by ISO 9001-certified testing.

>> Product Uses

1. Urban Power Distribution Networks

Widely adopted in city substations and residential complexes to step down 10kV to 400V for daily consumption. The oil-cooled design ensures silent operation (≤55dB) ideal for densely populated areas while meeting strict urban safety regulations.

2. Industrial Power Systems

Essential for manufacturing plants, mining operations and assembly lines requiring stable medium-voltage distribution. Its 150% overload capacity reliably supports heavy machinery startups and production peak loads.

3. Renewable Energy Integration

Commonly installed in solar/wind farms as grid-connection transformers. Special anti-corrosion treatment protects components in coastal/high-humidity environments, maintaining 98% efficiency despite renewable power fluctuations.

4. Rural Electrification Projects

Perfect for remote villages due to minimal maintenance requirements. Operates reliably in extreme conditions (-30°C~50°C) with automatic voltage regulation (±3%) for areas with unstable grid supply.

5. Critical Infrastructure Support

Deployed in hospitals, data centers and transportation hubs where power continuity is vital. The hermetically sealed tank prevents oil leakage, achieving IP55 protection for indoor/outdoor installations.
