Product Description

Product introduction

Introducing the pinnacle of power transformation technology: our three-phase oil-immersed power transformers, with a prestigious rated voltage range of 10-35kV. These engineering marvels are the ultimate choice for high-demand sectors such as petroleum, metallurgy, chemical, textile, and light industry, especially in challenging environments with elevated dust levels. Crafted to perfection, these transformers are designed to endure the toughest industrial demands, guaranteeing unmatched performance and unwavering reliability.
Capacity Range 30-2500kVA

Our transformers are a testament to superior engineering, delivering exceptional performance with high efficiency and minimal energy loss, all while maintaining impressively low noise levels. They feature outstanding internal heat dissipation and robust anti-short circuit capabilities. With negligible no-load and load losses, this transformer ensures reliable operation, an extended lifespan, and a maintenance-free experience, making it the indispensable choice for your power solutions.

This energy-saving, highly efficient secondary-class oil-immersed transformer exemplifies our company's commitment to pioneering innovation. Through the use of advanced materials, state-of-the-art technologies, and a unique blend of independent innovation with technology acquisition, we've revolutionized the core and coil structures. These enhancements markedly reduce no-load loss and noise, highlighting the outstanding results of our self-developed innovations.

 

Oil-immersed transformers offer a multitude of benefits, including superior heat dissipation capabilities that ensure consistent and stable operation. Known for their excellent insulation and high reliability, these transformers provide effortless voltage adjustments to accommodate diverse electrical requirements. Their mature technology and cost-effectiveness position them as the ideal choice for a wide array of applications.

Iron Core: Featuring a cutting-edge new generation of iron cores, our core is constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets. The full oblique jointed iron core, with its multi-stepped section design, ensures uniformity throughout the iron yoke and core, enhancing both efficiency and performance.

Winding: Our innovative winding design incorporates corrugated oil passages and foregoes immersion paint, secured with a tightening belt for unparalleled stability. The concentric coil design includes high-voltage windings with adjustable taps for precise voltage control, easily accessed via a tap changer on the box cover, allowing seamless post-power supply interruption voltage adjustments.

Safety Protection Device: Our transformers, ranging from 30-2000kVA, are fortified with advanced safety features, including a pressure relief valve. For heightened safety and operational integrity, a gas relay with alarm and trip terminals can be installed as per user specifications, ensuring peace of mind.
