Experience superior engineering with our product, characterized by exemplary efficiency, minimal energy loss, and whisper-quiet operation. Designed for outstanding internal heat dissipation and fortified anti-short circuit capabilities, this transformer delivers trustworthy, low-noise performance. Its low no-load and load loss ensure dependable operation, prolonged lifespan, and a maintenance-free experience, positioning it as a pivotal component for your power solutions.

This energy-saving marvel, our secondary-class oil-immersed transformer, epitomizes innovation. By harnessing state-of-the-art materials and pioneering technologies, we have seamlessly merged independent innovation with technology introduction to revolutionize core and coil structures. The result? A significant reduction in no-load loss and noise, which speaks volumes about the prowess of our self-developed products.

 

Oil-immersed transformers offer a multitude of advantages, including outstanding heat dissipation capabilities that assure stable operation. Renowned for their excellent insulation and unwavering reliability, these transformers provide easy voltage adjustments to meet diverse electrical needs. Their matured technology coupled with cost-effectiveness makes them the optimal choice for a wide array of applications.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, the core represents a new era of iron cores. The full oblique jointed design, featuring a multi-stepped section, ensures uniformity across the iron yoke and the core itself, amplifying efficiency and performance to new heights.

Winding: Our windings feature corrugated oil passages and a no immersion paint process, secured with a tightening belt to ensure unwavering stability. The concentric coil design boasts high-voltage windings with taps for precise voltage adjustments, easily accessible via a tap changer mounted on the box cover, facilitating seamless tap voltage modifications post power supply interruption.

Safety Protection Device: Our transformers, with capacities ranging from 30-2000kVA, are fortified with safety features like a pressure relief valve. For enhanced safety and operational integrity, a gas relay with alarm and trip terminals can be installed upon user request.
