They offer an unparalleled solution, artfully engineered to excel in environments laden with high dust concentrations, delivering unmatched performance and reliability. With these exceptional attributes, our transformers consistently meet and surpass the stringent demands of varied enterprises, offering a solution that is nothing short of superior excellence.
Capacity Range 30-2500kVA

Engineered with a focus on precision craftsmanship for peak performance, our product guarantees unrivaled efficiency with minimal energy loss and impressively low noise output. It features advanced internal heat dissipation capabilities and robust anti-short circuit properties. By significantly reducing both no-load and load losses, this transformer ensures reliable operation and promises an extended lifespan. Additionally, it offers a maintenance-free experience, establishing itself as an indispensable powerhouse for your energy solutions.

This state-of-the-art, energy-efficient, and energy-saving secondary-class oil-immersed transformer is the epitome of our dedication to innovation. By integrating cutting-edge materials and pioneering technologies, alongside a harmonious blend of independent innovation and technical adoption, we have optimized the core and coil structures. This revolutionary approach greatly reduces no-load loss and noise, underscoring the remarkable achievements of our self-developed products.

 

Oil-immersed transformers offer a multitude of advantages, including superior heat dissipation capabilities that ensure continuous, stable operation. Renowned for their outstanding insulation and high reliability, these transformers enable effortless voltage adjustments to meet a variety of electrical requirements. Their mature technology combined with cost-effectiveness makes them the ideal choice for numerous applications.

Iron Core: Our state-of-the-art iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new dawn of innovation. This fully oblique jointed iron core features a multi-stepped section design that guarantees uniformity throughout the iron yoke and core, significantly boosting efficiency and performance.

Winding: Our meticulously crafted windings feature corrugated oil passages and a no immersion paint process, secured with a tightening belt for enhanced stability. The concentric coil design includes high-voltage windings with taps for precise voltage adjustments, accessible through a tap changer mounted on the box cover. This enables seamless voltage modifications after a power supply interruption, ensuring unmatched adaptability.

Safety Protection Device: Our transformers, with capacities ranging from 30 to 2000kVA, come equipped with vital safety features like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed per user requirements, enhancing safety and operational reliability.
