Capacity Range 30-2500kVA

Our product, crafted with an unwavering commitment to excellence, delivers superior efficiency with minimal energy loss and impressively low noise levels. Boasting exceptional heat dissipation and robust anti-short circuit properties, it significantly reduces both no-load and load loss, ensuring reliable operation and longevity. Furthermore, it offers a maintenance-free experience, making it an indispensable asset for your power solutions.

Positioned at the cutting edge of technology, this advanced energy-saving, energy-efficient secondary-class oil-immersed transformer showcases our steadfast commitment to innovation. By integrating pioneering materials with groundbreaking technologies, and blending independent innovation with technology adoption, the core and coil structures are optimized. This innovative approach greatly minimizes no-load loss and noise, highlighting the remarkable results of our self-developed products.

 

Oil-immersed transformers offer a multitude of benefits, including superior heat dissipation that ensures continuous and stable operation. Renowned for their exceptional insulation and reliability, these transformers facilitate seamless voltage adjustments to suit various electrical requirements. With mature technology and cost-effectiveness, they are the perfect choice for numerous applications.

Iron Core: Our advanced iron core, created from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, represents 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 boosting efficiency and performance.

Winding: Our expertly engineered windings feature corrugated oil passages and employ 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 enables seamless voltage alterations after a power supply interruption, ensuring unparalleled adaptability.

Safety Protection Device: Our transformers, with capacities ranging from 30 to 2000kVA, are equipped with vital safety features such as a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed according to user requirements, enhancing safety and operational reliability.
