Product Description

Product introduction

Introducing our exceptional three-phase oil-immersed power transformers, crafted with precision to operate effortlessly within a voltage range of 10-35kV. These masterpieces of engineering are designed to serve a vast array of industries, including petroleum, metallurgy, chemical, textile, and light industry. They provide the ultimate solution for environments laden with dust, ensuring not only unmatched performance but also exceptional reliability. These transformers are crafted to meet and exceed the stringent demands of various industries, delivering excellence with every operation.
Capacity Range 30-2500kVA

Our product, crafted with a keen focus on excellence, promises superior efficiency with minimal energy loss and impressively low noise levels. It features outstanding internal heat dissipation and robust anti-short circuit capabilities, markedly reducing both no-load and load loss. This ensures reliable operation and long-term durability, providing a maintenance-free experience and making it an indispensable asset for your power needs.

At the cutting-edge of technology, this advanced energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our commitment to innovation. By integrating pioneering materials and groundbreaking technologies, alongside a blend of independent innovation and technology adoption, we have optimized the core and coil structures. This revolutionary design significantly minimizes no-load loss and noise, showcasing the remarkable achievements of our proprietary products.

 

Oil-immersed transformers offer numerous advantages, including superior heat dissipation capabilities, ensuring continuous and stable operation. Renowned for exceptional insulation and high reliability, these transformers enable easy voltage adjustments to meet diverse electrical needs. Their mature technology and cost-effectiveness make them the preferred choice for a wide range of applications.

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

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

Safety Protection Device: Our transformers, with capacities 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, enhancing safety and operational reliability.

Apply	Mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings
Installation height	The altitude does exceed 1000m
The waveform of the power supply voltage	similar to a sine wave

Oil Temperature Measuring Device: Each transformer features a strategically placed glass thermometer in a tube holder atop the oil tank, extending 120±10 mm into the oil. For transformers from 1000-2000kVA, an outdoor signal thermometer is included, providing precise and reliable temperature monitoring.
