Electric Oil Immersed Power Transformer

Electric Oil-Immersed Low Loss Power Transformer

Introduction

Key Features

Energy Efficiency

• Reduced No-Load Losses: The S13 series transformers achieve a 30% reduction in no-load losses compared to the S11 series, significantly contributing to energy conservation and reduced operational costs
• High Efficiency: The S22 series transformers offer even higher efficiency, with a first-class energy efficiency index and an efficiency as high as 98%.

Advanced Materials and Design

• High-Quality Core Materials: The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, which are known for their superior magnetic properties. This material choice results in lower core losses and enhanced energy efficiency.
• Innovative Joint Structure: The transformers feature a multi-step progressive full-lap joint structure, which not only strengthens the core but also optimizes the magnetic flux path, leading to improved performance and durability.

Noise Reduction

• Quieter Operation: The S13 series features a design that reduces noise levels by 5-10 dB, making them suitable for urban and residential areas where noise pollution is a concern.

Outdoor Durability

• Robust Design: The transformers are designed to withstand harsh environmental conditions, ensuring reliable outdoor use. The fully sealed design prevents contact with the air, ensuring long-term reliability even in humid environments.

Safety Mechanisms

• Pressure Relief Valve: The transformers include a pressure relief valve for secure operation, ensuring safety and reliability in various operating conditions.

Technical Specifications

Core Design

• Innovative Lamination: The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, with a 45° full oblique shearing on the transverse shear line. The core column and yoke joint are in a five-step laminated structure, improving the magnetic field distribution and reducing energy consumption.

Winding

• Compact Foil Winding: The winding is made of copper foil, ensuring uniform distribution of operating current and improving the balance of the ampoule. The axial short-circuit force of the transformer is small, simplifying the winding pressing device and improving the short-circuit resistance of the transformer.

Tank

• Corrugated and Sealed: The fuel tank uses a corrugated design, made of high-quality cold-rolled steel sheet. The corrugated sheet is formed by a transformer corrugated oil tank automatic production line and is protected by argon gas. This design has the advantages of strong pressure, good elastic deformation, high heat dissipation coefficient, and no leakage during operation.

Applications

• Power Plants: Efficient energy generation and distribution.
• Electrical Grids: Reliable transmission of electricity.
• Industrial Facilities: Continuous and stable power supply for manufacturing and processing units.
• Urban Infrastructure: Sustainable power solutions for dense urban environments, including residential and commercial areas.
• Rural Electrification: Reliable power distribution infrastructure for agricultural activities and rural development.

Distinct Advantages

Economic Efficiency

• Long-Term Savings: The transformers offer a cost-effective solution for power distribution, with high efficiency and low maintenance requirements. The reduced energy losses lead to significant cost savings over the transformer's operational life.

Extended Lifespan

• Designed for Durability: These transformers are designed to provide a long service life, reducing the need for frequent replacements and minimizing costs. The robust design and high-quality materials ensure that the transformers remain operational for extended periods.

High Reliability

• Consistent Performance: The transformers guarantee high operational reliability, ensuring a stable power supply essential for critical applications. This reliability is crucial in environments where power outages can have significant consequences.

Space Efficiency

• Compact Design: The compact design of the transformers maximizes space utilization in power distribution facilities, making them ideal for installations with limited space. This design is particularly beneficial in urban and industrial settings where space is at a premium.
