Product Description

Product introduction

Our exceptional three-phase oil-immersed power transformers, engineered to operate within a rated voltage range of 10-35kV, are the premier choice for a myriad of industries such as petroleum, metallurgy, chemical, textile, and light industry. These transformers thrive in environments laden with high dust concentrations. Carefully crafted to meet and exceed the stringent demands of diverse enterprises, they ensure performance excellence and unparalleled reliability, making them indispensable assets in any industrial setting.
Capacity Range 30-2500kVA

Our state-of-the-art product is meticulously engineered for top-tier performance, boasting unparalleled efficiency, minimal energy loss, and impressively low noise levels. Designed with superior internal heat dissipation and robust protection against short circuits, this transformer shines with its low no-load and load loss features. It promises steadfast operation, a prolonged lifespan, and a maintenance-free experience, establishing itself as a rock-solid component for fulfilling all your power necessities with unwavering trust.

This energy-saving, class-leading secondary-class oil-immersed transformer epitomizes our unwavering commitment to cutting-edge innovation. By mixing pioneering new materials and state-of-the-art technologies with a blend of independent innovation and strategic technology adoption, we have dramatically refined the core and coil structures. This significant advancement sharply reduces no-load loss and noise, highlighting the remarkable achievements of our self-crafted products.

 

Oil-immersed transformers offer exceptional advantages, including superb heat dissipation capabilities that ensure a stable and resilient operation. They are celebrated for their excellent insulation and high reliability, providing easy voltage adjustments to meet diverse electrical demands. With their cost-effectiveness and mature technology, these transformers are a preferred solution for a wide range of applications.

Iron Core: Crafted from highly permeable magnetic grain-oriented cold-rolled silicon steel sheets, our iron core signifies a new generation in core technology. Featuring a full oblique jointed design with a multi-stepped section, it guarantees uniformity across the iron yoke and core, significantly boosting efficiency and performance.

Winding: Our advanced windings integrate corrugated oil passages and a no immersion paint process, stabilized with a tightening belt to ensure reliability. The concentric coil design includes high-voltage windings with taps for precise voltage tuning, conveniently accessible via a tap changer on the box cover, enabling seamless voltage adjustments after power interruptions.

Safety Protection Device: Our transformers, with capacities ranging from 30-2000kVA, come fortified with vital safety features like a pressure relief valve. Moreover, a gas relay equipped with alarm and trip terminals can be installed according to user specifications, significantly enhancing overall safety and operational integrity.
