Product Description

Product introduction

Our outstanding three-phase oil-immersed power transformers, equipped with a rated voltage range from 10 to 35kV, stand as the premier choice for a multitude of industries including petroleum, metallurgy, chemical, textile, and light industry sectors. Specially crafted to thrive in environments laden with high dust concentrations, these transformers are meticulously designed to meet the stringent demands of various enterprises, guaranteeing peak performance and unmatched reliability.
Capacity Range 30-2500kVA

Our product is ingeniously engineered to deliver unparalleled performance, showcasing supreme efficiency, minimal energy loss, and impressively low noise levels. It features exceptional internal heat dissipation and robust anti-short circuit capabilities. With reduced no-load and load loss, this transformer promises reliable operation, an extended lifespan, and a virtually maintenance-free experience, establishing itself as a steadfast component for your essential power requirements.

This transformative energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our unwavering commitment to innovation. By harnessing new materials, state-of-the-art technologies, and a harmonious blend of self-driven innovation with the introduction of advanced technology, we have meticulously optimized and revolutionized the core and coil structures. This groundbreaking development significantly diminishes no-load loss and noise, reflecting the triumph of our proprietary products.

 

Oil-immersed transformers offer a multitude of advantages, including superior heat dissipation capabilities that ensure stable and uninterrupted operation. Renowned for their exceptional insulation and high reliability, these transformers provide effortless voltage adjustments, catering to a broad spectrum of electrical needs. Their well-established technology and cost-effectiveness make them an ideal choice for a diverse range of applications.

Iron Core: The core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, marks a new era of iron cores. The fully oblique jointed iron core features a multi-stepped section design, ensuring uniformity across both the iron yoke and the core itself, thereby enhancing efficiency and performance to new heights.

Winding: Our windings are designed with corrugated oil passages and feature a no immersion paint process, ensuring stability with a tightening belt. 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 for seamless and efficient changes to the tap voltage following a power supply interruption.

Safety Protection Device: Our transformers, ranging from 30 to 2000kVA, are equipped with comprehensive safety features like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed based on user requirements, enhancing safety and operational integrity to the highest standards.

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 is equipped with a glass thermometer housed in a tube holder, strategically positioned atop the oil tank, extending 120±10 mm into the oil. For transformers in the 1000 to 2000kVA range, an outdoor signal thermometer is included to provide precise and reliable temperature monitoring.
