ISO9001& CNAS Oil-Immersed Type 10-35kv 30-25000kVA Supply 63kVA Copper Power Transformer

Product Description

Product introduction
Our three-phase oil-immersed power transformers, with a rated voltage range of 10-35kV, are the go-to solution for industries including petroleum, metallurgy, chemical, textile, and light industry, especially in environments with high dust concentrations. These transformers are designed to meet the rigorous demands of various enterprises, ensuring optimal performance and reliability.
Capacity Range 30-2500kVAOur product is engineered for superior performance, featuring high efficiency, minimal energy loss, and remarkably low noise levels. It boasts excellent internal heat dissipation and robust anti-short circuit capabilities. With low no-load and load loss, this transformer promises dependable operation, extended lifespan, and a maintenance-free experience, making it a trustworthy component for your power needs.This energy-saving, energy-efficient secondary-class oil-immersed transformer is a testament to our company's dedication to innovation. By leveraging new materials, cutting-edge technologies, and a blend of independent innovation with technology introduction, we have optimized and revolutionized the core and coil structures. This development significantly minimizes no-load loss and noise, showcasing the fruits of our self-developed products. Oil-immersed transformers provide numerous benefits, including exceptional heat dissipation capabilities that ensure stable operation. These transformers are renowned for their excellent insulation and high reliability. They offer easy voltage adjustments, catering to diverse electrical requirements, while their matured technology and cost-effectiveness make them an ideal choice for various applications.
Iron Core: The core, constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, represents a new generation of iron cores. The full oblique jointed iron core features a multi-stepped section design, ensuring uniformity across the iron yoke and the core itself, enhancing efficiency and performance.
Winding: Our windings utilize corrugated oil passages and a no immersion paint process, secured with a tightening belt for 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 for seamless changes to the tap voltage post power supply interruption.
Safety Protection Device: Our transformers, ranging from 30-2000kVA, are equipped with safety features like a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed as per user requirements, 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 comes fitted with a glass thermometer in a tube holder, strategically positioned 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 accurate and reliable temperature monitoring.
