Eco-friendly S13 Oil Immersed Transformer with Advanced Features

S13 Series Oil Immersed Transformer

The S13 series oil-immersed transformers represent a significant advancement in power distribution technology, focusing on enhanced energy efficiency and environmental sustainability. These oil transformer build upon the legacy of the S9 and S11 models, offering improved performance and reduced environmental impact through advanced engineering and design.

The oil immersed transformer is similar to the transformer in structure. It is one of the transformer types classified by the form of insulation of the core. Therefore, it has the recognizable feature of oil immersed coils which reduces the thermal image of the equipment in it. The basic elements of the oil immersed type consist of the core, windings and bushings. The core provides a path for the magnetic flow. The winding creates a magnetic field. It consists of a coil of conductor, wound around the core and insulated with a paperboard barrier and shield. The thickness of the insulation layer of the winding increases with the voltage. The bushing connects the transformer winding to the substation. The oil transformer is used in power distribution or substations. Their core and coils are immersed in oil, which cools and insulates. The oil circulates through the pipes in the coils and around the coils and core assembly by moving by convection. The oil is cooled externally by the tank in small ratings and by air-cooled radiators in large ratings.

Features of oil-immersed transformers

1) When used with fiber materials, it has good insulation performance, can reduce insulation distance and reduce costs.

2) Transformer oil has low viscosity and good heat transfer performance.

3) It can well protect the core and winding from the influence of moisture in the air.

4) It protects the insulation paper and insulation cardboard from the effect of oxygen, reduces the aging of insulation materials and prolongs the life of the transformer.

At present, except for some small and medium-capacity transformers and gas transformers for special purposes, most large and medium-sized transformers still use transformer oil as cooling and insulation medium.

Key Benefits

Optimized Core MateriaSuperior Silicon Steel: The S13 series uses 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.

Significant Energy Reduction

25% Less No-Load Losses: Compared to the S11 series, the S13 series achieves a significant 25% reduction in no-load losses, contributing to energy conservation and aligning with global emission reduction standards.
80% Less No-Load Current: The no-load current is reduced by 80%, further enhancing energy efficiency and reducing operational costs.

Quieter Operation

Reduced Noise Levels: 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 S13 series is designed to withstand harsh environmental conditions, making them suitable for reliable outdoor use. The fully sealed design prevents contact with the air, ensuring long-term reliability even in humid environments.

Safety Mechanism

Pressure Relief Valve: The S13 series includes 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.
