Introduction to Oil-Immersed Transformers
An Oil-Immersed Transformer is a highly reliable power device where the core and windings are immersed in insulating oil for cooling and insulation. Known for their durability, high overload capacity, and cost-effectiveness, they are the cornerstone of utility and industrial power distribution networks worldwide.
At Jiangxi Kaihao Electric Equipment Co., Ltd., we manufacture sealed oil-immersed transformers that excel in harsh environments. Our products comply with the latest national standards, including GB/T 6451-2023 and GB 20052-2024 for energy efficiency.
Key Features and Technical Advantages
Our oil-immersed transformers are built for longevity and stable performance in diverse conditions.
Sealed, Maintenance-Free Design: We employ a fully sealed corrugated tank design that replaces the traditional conservator. This effectively prevents moisture and oxygen from entering, slowing down oil aging and eliminating the need for regular oil maintenance.
Excellent Heat Dissipation and Overload Capacity: The insulating oil provides superior heat transfer. Under forced oil circulation cooling, the transformer can handle significant temporary overloads, making it ideal for applications with fluctuating demand.
High Mechanical Strength and Safety: The windings are securely clamped, and structures are fitted with self-locking nuts to withstand transportation vibration. Advanced vacuum drying and oil filtration during manufacturing minimize internal moisture, ensuring long-term insulation integrity.
Energy Efficient and Low Noise: The core is made from high-grade, laser-etched grain-oriented silicon steel with a multi-step lap joint structure, which minimizes no-load losses and reduces operating noise.
Technical Specifications and Applications
Engineered for resilience, our transformers are the default choice for primary power distribution.
Typical Specifications:
Rated Capacity: 30 to 2500 kVA
Rated Voltage: 10 kV
Temperature Limits: Top oil temperature is typically monitored, with an alarm set at 80°C and a maximum limit of 90°C to protect insulation life.
Application Environment: Suitable for altitudes up to 1000m and ambient temperatures from -25°C to +40°C.
Ideal Application Scenarios:
Utility & Grid Networks: Pole-mounted and ground-based distribution for urban and rural grid改造.
Industrial Powerhouses: Factories, mining operations, oil & gas fields, and large plants requiring robust and continuous power supply.
Renewable Energy Farms: Step-up substations for large-scale solar and wind power generation facilities.
Infrastructure: Water treatment plants, irrigation systems, and outdoor substations exposed to weather.
