They offer a perfect solution for challenging environments with high dust concentrations, promising unparalleled performance coupled with unmatched reliability. These outstanding transformers are designed to rise above stringent business demands, consistently delivering supreme excellence and dependability.
Capacity Range 30-2500kVA

Our precision-engineered transformer is dedicated to achieving peak excellence, offering exceptional efficiency with minimal energy wastage, and impressively low noise levels. It features remarkable internal heat dissipation capabilities and robust anti-short circuit properties. By significantly reducing both no-load and load loss, this transformer ensures reliable operation and extended longevity. Moreover, it provides a maintenance-free experience, making it an indispensable asset for your power needs.

At the cutting edge of technology, this advanced energy-saving, energy-efficient secondary-class oil-immersed transformer exemplifies our relentless dedication to innovation. Through the integration of pioneering materials with groundbreaking technologies, alongside an optimal mix of self-driven innovation and technology adaptation, we have optimized the core and coil structures. This revolutionary method substantially minimizes no-load loss and noise, showcasing the extraordinary outcomes of our self-developed products.

 

Oil-immersed transformers bring a multitude of benefits, including superior heat dissipation capabilities that guarantee continuous and stable performance. Renowned for exceptional insulation and high reliability, these transformers facilitate seamless voltage adjustments to meet diverse electrical needs. Their well-established technology and cost-effectiveness make them the ideal choice across a broad spectrum of applications.

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

Winding: Our expertly 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 design allows for seamless voltage alterations post power supply interruption, ensuring unmatched adaptability.

Safety Protection Device: Our transformers, with capacities ranging from 30 to 2000kVA, are equipped with vital 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 reliability.
