With precision engineering tailored for optimal performance, our transformers guarantee high efficiency, minimal energy loss, and remarkably low noise levels. Featuring excellent internal heat dissipation and robust anti-short circuit capabilities, they ensure reduced no-load and load loss. Experience reliable operation, an extended product lifespan, and a maintenance-free journey, making our transformers an indispensable component of your power solutions.

Embark on an energy-saving revolution with our cutting-edge, energy-efficient secondary-class oil-immersed transformer. Our commitment to innovation shines through as we integrate advanced materials and groundbreaking technologies, blending independent innovation with technology adoption. The optimized core and coil structures significantly curtail no-load loss and noise, symbolizing the extraordinary results of our self-developed products.

 

Oil-immersed transformers offer a plethora of advantages, including exceptional heat dissipation that guarantees continuous, stable operation. Renowned for their outstanding insulation and high reliability, these transformers provide effortless voltage adjustments to accommodate varying electrical requirements. Their mature technology and cost-efficiency make them the ideal choice for a vast array of applications.

Iron Core: Our pioneering iron core, fashioned from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, ushers in a new era of innovation. This fully oblique jointed iron core, featuring a multi-stepped section design, achieves uniformity across the iron yoke and core, markedly enhancing efficiency and performance.

Winding: Our intricately crafted windings come with corrugated oil passages and a no immersion paint process, secured by a tightening belt for enhanced stability. The concentric coil design incorporates high-voltage windings with taps for precise voltage adjustments, accessible via a tap changer on the box cover, enabling seamless voltage modifications after power supply interruption.

Safety Protection Device: Our transformers, spanning a capacity range of 30-2000kVA, feature crucial safety elements like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed as per user demands, bolstering safety and operational reliability.
