Perfectly suited for environments with elevated dust levels, these transformers are crafted to meet the exacting demands of diverse enterprises, guaranteeing unmatched performance and unwavering reliability.
Capacity Range 30-2500kVA

Our cutting-edge product is meticulously engineered to deliver peak performance, showcasing high efficiency and minimal energy loss with impressively low noise levels. It features outstanding internal heat dissipation and formidable anti-short circuit capabilities. With an emphasis on low no-load and load loss, this transformer assures consistent operation, a prolonged lifespan, and a maintenance-free experience, making it an indispensable asset for your power infrastructure.

This transformative energy-saving secondary-class oil-immersed transformer embodies our company's unwavering commitment to pioneering innovation. By harnessing state-of-the-art materials and cutting-edge technologies, we have seamlessly integrated independent innovation with technological imports, revolutionizing the core and coil structures. This advancement dramatically reduces no-load loss and noise, proudly highlighting the excellence of our self-developed products.

 

The benefits of oil-immersed transformers are manifold, including superior heat dissipation capabilities that ensure consistent and stable operation. Renowned for their exceptional insulation and high reliability, these transformers facilitate easy voltage adjustments, meeting a wide range of electrical needs. Their well-established technology and cost-efficiency make them the ideal choice for numerous applications, offering unmatched value and dependability.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, the core represents the next generation of iron cores. Its full oblique jointed design with a multi-stepped section ensures uniformity in the iron yoke and core, significantly boosting efficiency and performance, setting a new standard in transformer design.

Winding: Our windings are designed with precision, incorporating corrugated oil passages and a non-painted immersion process, secured with a tightening belt for enhanced stability. The concentric coil design includes high-voltage windings with adjustable taps, accessible through a tap changer mounted on the box cover, allowing for seamless voltage adjustments after power supply interruption, ensuring flexibility and control.

Safety Protection Device: Our transformers, covering a range from 30-2000kVA, are equipped with advanced safety features such as a pressure relief valve. Additionally, an optional gas relay with both alarm and trip terminals can be installed to meet user specifications, enhancing safety and operational integrity, providing peace of mind and reliability in every application.
