Product Description

Product introduction

Introducing our prestigious three-phase oil-immersed power transformers, engineered with a rated voltage spectrum of 10-35kV. These transformers are the quintessential choice for a myriad of industries such as petroleum, metallurgy, chemical, textile, and light industry. They thrive exceptionally well in high-dust environments, delivering unmatched performance and dependability to fulfill the rigorous demands of various enterprises.
Capacity Range 30-2500kVA

Meticulously crafted for unparalleled excellence, our product offers remarkable efficiency, minimal energy consumption, and astonishingly low noise levels. It boasts superior internal heat dissipation and robust anti-short circuit capabilities. With minimal no-load and load loss, this transformer assures reliable operation, an extended service life, and a hassle-free maintenance experience, making it an essential component of your power infrastructure.

This cutting-edge, energy-saving, and energy-efficient secondary-class oil-immersed transformer is a testament to our dedication to innovation. By integrating state-of-the-art materials, breakthrough technologies, and a symbiotic fusion of independent innovation with technology assimilation, we have refined and revolutionized the core and coil structures. This evolution greatly diminishes no-load loss and noise, showcasing the remarkable efficacy of our self-developed products.

 

Oil-immersed transformers present a plethora of benefits, including superior heat dissipation capabilities that ensure consistent and stable performance. Celebrated for their exceptional insulation and high dependability, these transformers facilitate effortless voltage tweaks to meet a variety of electrical requisites. Their mature technology and cost-effectiveness render them an ideal choice for numerous applications.

Iron Core: Our avant-garde iron core, constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new frontier of innovation. This fully oblique jointed iron core features a multi-stepped section design, ensuring uniformity across the iron yoke and the core itself, significantly elevating efficiency and performance.

Winding: Our precisely engineered windings incorporate corrugated oil passages and a no immersion paint process, secured with a tightening belt for heightened stability. The concentric coil design incorporates high-voltage windings with taps for exact voltage adjustments, accessible via a tap changer mounted on the box cover, facilitating seamless voltage modifications after a power interruption.

Safety Protection Device: Our transformers, with a capacity range of 30-2000kVA, are equipped with vital safety features like a pressure relief valve. Furthermore, a gas relay with alarm and trip terminals can be installed according to user specifications, augmenting safety and operational integrity.
