Product Description

Product introduction

Introducing our esteemed three-phase oil-immersed power transformers, masterfully crafted to operate within a rated voltage range of 10-35kV. These transformers serve as the ultimate powerhouse for a diverse array of industries including petroleum, metallurgy, chemical, textile, and light industry. Built to thrive in high dust concentration environments, they deliver unparalleled performance and reliability, meeting the rigorous demands of enterprises with exceptional excellence.
Capacity Range 30-2500kVA

Expertly engineered for unparalleled excellence, our product guarantees high efficiency with minimal energy loss, complemented by impressively low noise output. It features superior internal heat dissipation capabilities and robust anti-short circuit properties. With reduced no-load and load loss, this transformer not only promises reliable operation and extended lifespan but also offers a maintenance-free experience, establishing itself as an indispensable asset for your power solutions.

This state-of-the-art, energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our commitment to innovation. By integrating advanced materials and groundbreaking technologies along with a harmonious fusion of independent innovation and technology adoption, we've optimized the core and coil structures. This innovation significantly reduces no-load loss and noise, demonstrating the impressive outcomes of our self-developed products.

 

Oil-immersed transformers offer a myriad of benefits, including excellent heat dissipation capabilities that ensure continuous and stable operation. Renowned for their superior insulation and high reliability, these transformers allow for effortless voltage adjustments to meet diverse electrical needs. Their mature technology and cost-efficiency make them the perfect choice for a wide range of applications.

Iron Core: Our state-of-the-art iron core, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, heralds a new era of innovation. This fully oblique jointed iron core, with its multi-stepped section design, ensures consistency throughout the iron yoke and core, significantly enhancing efficiency and performance.

Winding: Our intricately designed windings are equipped with corrugated oil passages and a no immersion paint process, secured with a tightening belt for enhanced stability. The concentric coil design features high-voltage windings with taps for precise voltage adjustments, accessible via a tap changer mounted on the box cover, allowing for seamless voltage alterations post power supply interruption.

Safety Protection Device: Our transformers, covering a capacity range of 30-2000kVA, come equipped with essential safety features such as a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed based on user requirements, boosting safety and operational fidelity.
