Product Description

Product introduction

Our state-of-the-art three-phase oil-immersed power transformers, with an impressive rated voltage range from 10-35kV, stand as the prime solution for industries such as petroleum, metallurgy, chemical, textile, and light industry. These transformers are expertly crafted to withstand even the most challenging environments, including those with high dust concentrations. They are meticulously designed to fulfill the rigorous demands of diverse enterprises, ensuring both optimal performance and unwavering reliability.
Capacity Range 30-2500kVA

Crafted for excellence, our product offers superior performance with exceptional efficiency, reduced energy loss, and impressively low operational noise. It features outstanding internal heat dissipation and robust anti-short circuit capabilities. With minimal no-load and load loss, this transformer ensures reliable functionality, prolonged lifespan, and a virtually maintenance-free experience, establishing it as an indispensable and trustworthy component for all your power requirements.

This groundbreaking energy-efficient, energy-saving secondary-class oil-immersed transformer epitomizes our commitment to innovation. Through the use of advanced materials and pioneering technologies, coupled with a harmonious blend of independent innovation and technology introduction, we have refined and revolutionized the core and coil structures. This innovation substantially reduces no-load loss and noise, exemplifying the pinnacle of our self-developed products.

 

Oil-immersed transformers deliver a plethora of advantages, including unparalleled heat dissipation capabilities that guarantee consistent and stable operation. Celebrated for their superb insulation and impressive reliability, these transformers allow for straightforward voltage adjustments, catering to a wide array of electrical needs. Their mature technology and cost-effectiveness render them an optimal choice for numerous applications.

Iron Core: Our cutting-edge iron core, built from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, exemplifies a new generation of iron cores. The fully oblique jointed iron core features a multi-stepped section design, ensuring perfect uniformity across both the iron yoke and the core itself, significantly boosting efficiency and performance.

Winding: Our meticulously designed windings incorporate corrugated oil passages and operate without an immersion paint process, secured with a tightening belt for enhanced stability. The concentric coil design includes high-voltage windings equipped with taps for precise voltage adjustments, easily accessible via a tap changer mounted on the box cover. This feature allows for smooth and seamless voltage changes post power supply interruption.

Safety Protection Device: Our transformers, with capacities ranging from 30-2000kVA, are equipped with advanced safety features like a pressure relief valve. Additionally, an optional gas relay with alarm and trip terminals can be installed according to user specifications, elevating safety and enhancing operational integrity.
