Product Description

Product introduction

Our esteemed three-phase oil-immersed power transformers, crafted with a rated voltage range of 10-35kV, are the ultimate solution for an extensive spectrum of industries, such as petroleum, metallurgy, chemical, textile, and light industry. Designed to excel in high dust concentration environments, these transformers offer unmatched performance and exceptional reliability, meeting the rigorous demands of various enterprises with excellence.
Capacity Range 30-2500kVA

Our expertly engineered transformer is a pinnacle of efficiency, ensuring minimal energy loss, low noise output, and superior heat dissipation. Its robust anti-short circuit properties, combined with reduced no-load and load losses, guarantee reliable and maintenance-free operation, extending its lifespan, making it an indispensable asset for your power solutions.

This state-of-the-art energy-saving and energy-efficient secondary-class oil-immersed transformer epitomizes our commitment to innovation. By integrating cutting-edge materials and pioneering technologies, our independent innovations have refined core and coil structures, drastically reducing both no-load loss and noise, and demonstrating the remarkable breakthroughs of our self-developed products.

 

Oil-immersed transformers offer a plethora of advantages, including exceptional heat dissipation capabilities for continuous and stable operation. Renowned for their superior insulation and reliability, these transformers provide effortless voltage adjustments to meet varied electrical requirements, with mature technology and cost-efficiency making them ideal for numerous applications.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, our cutting-edge iron core represents a new era of innovation. Featuring a fully oblique jointed and multi-stepped section design, it ensures uniformity throughout the iron yoke and core, significantly enhancing efficiency and performance.

Winding: Our intricately designed windings incorporate corrugated oil passages and a no immersion paint process, secured by a tightening belt for enhanced stability. The concentric coil includes high-voltage windings with taps for precise voltage adjustments, easily accessible via a tap changer on the box cover for seamless alterations after power supply interruption.

Safety Protection Device: Equipped with a capacity range of 30-2000kVA, our transformers include crucial safety features such as a pressure relief valve and optional gas relay with alarm and trip terminals based on user requirements, ensuring enhanced safety and operational fidelity.
