200kva Copper Winding S13 Series Oil Immersed Transformer

Oil Immersed Power Transformers: Features, Applications, and Selection Considerations

200kva copper winding s13 series oil immersed power transformers are widely used throughout modern electrical networks. The primary function of an oil immersed transformer is to convert voltage levels and distribute electrical energy efficiently to different types of loads. Operating on the principle of electromagnetic induction,200kva copper winding s13 series oil immersed transformers can increase or decrease alternating current voltage as required, to make them suitable for a broad range of applications in power utilities, industrial facilities, and agricultural systems. Their design combines effective cooling, reliable insulation, and long service life, allowing them to perform in both indoor and outdoor environments.

Technical Principles and Main Components

The main elements of a 200kva copper winding s13 series oil immersed transformer are the magnetic core, the windings, and the insulating oil. The core is generally manufactured from high quality silicon steel laminations arranged to reduce eddy current losses and improve magnetic performance. Depending on the design requirements, the windings may be made from copper conductors and are configured into high voltage and low voltage coils.

The transformer tank is filled with insulating oil, which performs two important functions. It provides electrical insulation between energized components while also carrying heat away from the windings and core. Heat generated during operation is transferred through the oil and then dissipated through the tank surface into the surrounding air. This cooling process helps maintain stable operating temperatures and supports long term reliability. The enclosure is designed to prevent the entry of dust and foreign objects, ensuring safe operation in a variety of environments.

Performance Characteristics and Typical Applications

Oil immersed transformers are available in a wide range of capacities, commonly including ratings from 25 kVA to 4000 kVA. Typical voltage configurations may include a high voltage side rated at 10 kV and a low voltage side rated at 400 V. Impedance values and load losses vary according to transformer capacity and design requirements.

200kva copper winding s13 series oil immersed transformers are engineered to operate under demanding environmental conditions, which includes both low temperature and high temperature regions. Their three phase configuration meets the requirements of industrial power systems, while strong electromagnetic compatibility helps minimize interference with nearby equipment.

Common applications include utility substations, factory distribution networks, agricultural irrigation stations, commercial buildings, and other facilities that require a dependable and stable power supply.

Technical Advantages and Safety Features

Compared with dry type transformers,200kva copper winding s13 series oil immersed transformers offer several distinct advantages. The insulating oil provides a higher dielectric strength than air, which allows for a more compact electrical design while maintaining reliable insulation performance. In addition, the oil absorbs and transfers heat more effectively. It helps to reduce thermal stress and to extend equipment life.

Moisture protection is another important benefit. The oil surrounds the internal components and acts as a barrier against humidity, which makes oil immersed transformers especially suitable for areas with elevated moisture levels.

From a safety perspective, transformer tanks are commonly equipped with pressure relief devices. If an internal fault causes pressure to rise beyond a safe limit, the device automatically releases excess pressure to help protect the equipment from severe damage. Wenzhou XiFa Electrical Power Equipment Co., Ltd also offer customized designs, which includes different core configurations and winding materials, to meet special installation requirements or unique load characteristics.

Selection and Operational Considerations

Selecting the appropriate oil immersed transformer begins with a careful evaluation of the expected load. For example, installations supplying large motors often require additional capacity to accommodate starting currents and future expansion. Environmental conditions should also be considered when choosing the enclosure design and protection level, particularly for outdoor installations exposed to rain, dust, or harsh weather conditions.

Regular maintenance is essential for reliable operation. The condition of the insulating oil should be monitored periodically, including checks for moisture content and chemical degradation. When oil quality falls outside acceptable limits, corrective actions such as oil replacement or regeneration should be carried out.

For extended periods of storage or shutdown, proper preservation measures are necessary to protect the transformer from moisture ingress. During any inspection or maintenance activity, the equipment must be fully isolated from the power supply and appropriate safety procedures should be followed to prevent electrical hazards.

With their excellent insulation properties, efficient cooling performance, and proven reliability, oil immersed power transformers continue to play a critical role in ensuring stable and efficient power distribution across a wide variety of industries and infrastructure projects worldwide.
