Product Description

Product introduction

Our expertly crafted three-phase oil-immersed power transformers, with a versatile rated voltage range of 10-35kV, stand as the preferred choice for diverse industrial sectors such as petroleum, metallurgy, chemical, textile, and light industry. These transformers excel in environments characterized by high dust concentrations. Engineered to surpass the rigorous demands of various enterprises, they ensure optimal performance and unwavering reliability, positioning them as indispensable assets.
Capacity Range 30-2500kVA

Our product is a marvel of engineering, designed for superior performance. It features exceptional efficiency, minimal energy loss, and impressively low noise levels. With outstanding heat dissipation and robust anti-short circuit abilities, our transformer ensures reliability with low no-load and load loss. This translates to a maintenance-free experience and an extended lifespan, making it a trusted component for your power solutions.

This energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our commitment to innovation. By harnessing advanced materials, cutting-edge technologies, and combining independent innovation with technology adoption, we have optimized and revolutionized the core and coil structures. This progression significantly reduces no-load loss and noise, highlighting the achievements of our self-developed products.

 

Oil-immersed transformers offer a myriad of benefits, renowned for their exceptional heat dissipation capabilities that ensure stable operation. These transformers are celebrated for their outstanding insulation and high reliability, offering easy voltage adjustments to meet various electrical needs. Their mature technology and cost-effectiveness make them an ideal choice for a wide range of applications.

Iron Core: Constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, the core represents a new generation of iron cores. The full oblique jointed iron core incorporates a multi-stepped section design, ensuring uniformity across the iron yoke and core, thereby enhancing efficiency and performance.

Winding: Our meticulously designed windings feature corrugated oil passages and a no immersion paint process, 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 mounted on the box cover. This allows seamless voltage changes post power supply interruption.

Safety Protection Device: Our transformers, spanning 30-2000kVA, are equipped with comprehensive safety features such as a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed to meet user specifications, significantly enhancing safety and operational integrity.

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 fitted with a glass thermometer in a tube holder, strategically placed atop the oil tank, extending 120±10 mm into the oil. For transformers in the 1000-2000kVA range, an outdoor signal thermometer is included, providing precise and trustworthy temperature monitoring.
