Product Description

Product introduction

Our three-phase oil-immersed power transformers, boasting an impressive rated voltage range of 10-35kV, are the premier choice for a spectrum of industries such as petroleum, metallurgy, chemical, textile, and light industry, particularly in environments laden with high dust concentrations. Carefully crafted to meet the stringent demands of diverse enterprises, these transformers ensure unparalleled performance and reliability.
Capacity Range 30-2500kVA

Crafted for superior excellence, our product showcases exceptional performance characterized by high efficiency, minimal energy loss, and impressively low noise levels. It features outstanding internal heat dissipation and robust anti-short circuit capabilities. With both low no-load and load loss, this transformer assures reliable operation, a prolonged lifespan, and a maintenance-free experience, establishing itself as a steadfast component for your power needs.

This energy-saving, highly efficient secondary-class oil-immersed transformer exemplifies our company's unwavering commitment to innovation. By harnessing new materials and state-of-the-art technologies, alongside a blend of independent innovation with technology introduction, we have optimized and transformed the core and coil structures. This revolutionary development significantly reduces no-load loss and noise, highlighting the success of our self-developed products.

 

Oil-immersed transformers offer a multitude of advantages, including superior heat dissipation capabilities that guarantee stable operation. Renowned for their excellent insulation and high reliability, they allow for straightforward voltage adjustments to meet various electrical requirements. Their mature technology and cost-effectiveness make them an ideal choice for numerous applications.

Iron Core: The core is meticulously constructed from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, representing a new generation of iron cores. The completely oblique jointed iron core boasts a multi-stepped section design, ensuring uniformity across the iron yoke and the core itself, thereby enhancing efficiency and performance.

Winding: Our 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, facilitated by a tap changer mounted on the box cover. This allows for seamless changes to the tap voltage after power supply interruption.

Safety Protection Device: Our transformers, ranging from 30-2000kVA, are equipped with advanced safety features such as a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed based on user requirements, significantly enhancing safety and operational integrity.
