tap changers are well suited for oil immersed transformer
tap‑changers are well‑suited for oil‑immersed transformer
As a professional manufacturer of general-purpose transformer tap changers, our company prioritizes precision manufacturing, strict process control and full-cycle quality assurance. We adopt standardized and traceable procedures covering the entire production chain: incoming raw material inspection, CNC machining, product assembly and final performance verification.
Our experienced production team operates in compliance with stringent work instructions to guarantee all components satisfy dimensional tolerance and material stability requirements. Core production links incorporate automated assembly lines, precision welding and voltage withstand tests for tap changers, with all test results validated by our in-house laboratory. Prior to shipment, every finished unit is subject to a complete set of functional inspections, covering appearance check, contact pressure measurement, contact resistance test and mechanical endurance assessment.
- MOQ: There is no minimum order quantity. Larger orders can help cut down unit transportation costs.
- Lead time: The production lead time is subject to the order quantity.
- Payment terms: 50% TT deposit prior to production; the remaining 50% TT before shipment.
- Shipping terms: We can offer FOB, CIF and other trade terms.
Tap-changers are core voltage-regulating components for oil-immersed transformers rated up to 35 kV, widely deployed in medium and low-voltage distribution systems.
This series of off-circuit tap-changers features a compact structure, simple mechanical design and reliable performance. Tap position adjustment can only be performed when the transformer is completely de-energized. Manufactured with high-strength insulating materials and wear-resistant conductive components, these tap-changers are well suited for oil-immersed operating environments, delivering outstanding resistance to ageing, vibration and temperature variation. Tap selection is achieved via simple manual rotation, resulting in minimal maintenance requirements over the product service life.
Typical application scenarios cover urban and rural distribution networks, industrial parks, residential complexes and small power stations. By adjusting the transformer transformation ratio, the tap-changer stabilizes output voltage and mitigates voltage deviations arising from load changes and line losses.
