6KV-22KV Electric Oil Immersed Power Transformer/Distribution Transformer

Our company's oil-immersed transformer series has become a leader in the field of power supply due to its excellent performance, safety and stability, as well as durability. The product line covers various models from S9 to S22, suitable for voltage ranges from 6kv to 35kv, with a capacity ranging from 15kva to 31500kva, meeting the needs of various scenarios.

We adopt high-conductivity H62 material for the conductive rod to reduce heat generation and ensure stable equipment operation. The all-new mineral insulating oil guarantees excellent insulating performance and prolongs the product lifespan. The tank is made of high-quality steel plates and profiles, complying with national standards, ensuring high mechanical strength and durability.

Our transformers are designed with a focus on energy efficiency, low temperature rise, and strong load capacity, capable of long-term continuous full-load stable operation. Our oil-immersed transformers are reliable power supply solutions worthy of your trust, providing stable and dependable support for your power needs.

Low loss: TSTY's transformer core uses high magnetic permeability silicon steel sheets, high-purity copper or aluminum as winding materials, fully automatic longitudinal shearing line, cross-cutting line and stacking line equipment, reasonable core and winding structure, etc., to ensure the low loss of oil-immersed transformers.

Low noise: When manufacturing the core, we use high-quality high-magnetic permeability silicon steel sheets, design low magnetic flux density, and use automatic lamination machines to control the lamination accuracy to reduce the electromagnetic noise of the core.

No oil leakage: We have upgraded the strength and rigidity of the transformer oil tank to make it have a strong bearing capacity to avoid oil leakage due to oil tank deformation. Optimize the sealing structure design, use reliable sealing grooves, gasket forms and sizes to ensure the reliability of the seal. The oil storage cabinet has undergone positive and negative pressure leakage tests to ensure that there is no oil leakage during normal operation.

Strong short-circuit resistance: In order to enhance the short-circuit resistance of the transformer, ensure that the transformer can withstand short-circuit current without thermal damage or mechanical damage. We have optimized and transformed the design, manufacturing and materials.

1. In terms of design, we optimize the winding structure and the reasonable design of short-circuit impedance, integrate winding assembly and compression, and ensure precise assembly and short-circuit resistance.

2. In the winding process, advanced winding equipment and processes are used to ensure that the wires are closely arranged; when assembling the core, ensure that the core laminations are tight and neat; in the overall assembly process of the transformer, strictly control the installation tightness of each component.

3. We perform precise calculations on the strength and stiffness of the core clamping components to meet the safety requirements of the maximum short-circuit mechanical force.
