Product Description

Product introduction

Our esteemed three-phase oil-immersed power transformers are meticulously crafted to operate within a rated voltage range of 10-35kV. Masterfully designed for an astounding variety of industries, including petroleum, metallurgy, chemical, textile, and light industry, these transformers provide the ultimate solution. They are engineered to thrive in environments with high dust concentrations, delivering unparalleled performance and exceptional reliability. With these attributes, they consistently meet and exceed the rigorous demands of diverse enterprises, providing nothing short of excellence.
Capacity Range 30-2500kVA

Engineered with precision for peak excellence, our transformer is the epitome of high efficiency and minimal energy loss, coupled with remarkably low noise emissions. Featuring exceptional internal heat dissipation and robust resistance to short circuits, it reduces both no-load and load losses, ensuring steadfast reliability and longevity. Moreover, it promises a maintenance-free experience, making it an invaluable component of your power solutions.

This state-of-the-art energy-saving, energy-efficient secondary-class oil-immersed transformer epitomizes our unyielding commitment to innovation. With advanced materials and groundbreaking technologies, coupled with a seamless fusion of independent innovation and technology adoption, the optimized core and coil structures represent a revolutionary approach. This significantly reduces no-load loss and noise, underscoring the extraordinary capabilities of our self-developed products.

 

Oil-immersed transformers offer a multitude of benefits, including superior heat dissipation for stable, continuous operation. Renowned for exceptional insulation and high reliability, these transformers support effortless voltage adjustments tailored to various electrical needs. Their mature technology and cost-effectiveness make them the ideal choice for a wide array of applications.

Iron Core: Our cutting-edge iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, ushers in a new era of innovation. This fully oblique jointed iron core, with its multi-stepped section design, guarantees uniformity throughout the iron yoke and core, significantly enhancing efficiency and performance.

Winding: Our meticulously engineered windings feature corrugated oil passages and a no immersion paint process, secured with a tightening belt for increased stability. The concentric coil design includes high-voltage windings with taps for precise voltage adjustments, accessible via a tap changer mounted on the box cover. This allows seamless voltage alterations after power supply interruption, ensuring unmatched adaptability.

Safety Protection Device: Our transformers, with a capacity range from 30 to 2000kVA, come equipped with essential safety features like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed per user requirements, significantly enhancing safety and operational reliability.
