Product Description

Product introduction

Discover our prestigious collection of three-phase oil-immersed power transformers, meticulously crafted to operate within a robust rated voltage range of 10-35kV. These transformers are the quintessential solution for a diverse array of industries including petroleum, metallurgy, chemical, textile, and light industry sectors. Engineered to withstand high dust concentration environments, they offer unmatched performance, exceptional reliability, and are tailored to meet the demanding needs of various enterprises with outstanding excellence.
Capacity Range 30-2500kVA

Expertly crafted for peak performance, our transformers ensure high efficiency with minimal energy loss and impressively low noise. They feature superior internal heat dissipation and robust anti-short circuit capabilities. With reduced no-load and load loss, these transformers promise not just reliable operation, but also an extended lifespan and a maintenance-free experience, positioning them as indispensable assets for your power solutions.

This cutting-edge, energy-saving, energy-efficient secondary-class oil-immersed transformer represents our commitment to innovation. By leveraging advanced materials and pioneering technologies, combined with a blend of independent innovation and technological adoption, we've optimized the core and coil structures. This innovation significantly minimizes no-load loss and noise, embodying the remarkable results of our self-developed products.

 

Oil-immersed transformers offer a multitude of benefits, including superior heat dissipation capabilities that ensure continuous and stable operation. Renowned for their excellent insulation and high reliability, these transformers facilitate effortless voltage adjustments, catering to varied electrical needs. Their mature technology and cost-effectiveness make them the ideal choice for a wide range of applications.

Iron Core: Our cutting-edge iron core is crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, signaling a new era of innovation. This fully oblique jointed iron core, with its multi-stepped section design, guarantees uniformity across the iron yoke and core, substantially boosting efficiency and performance.

Winding: Our intricately designed windings incorporate corrugated oil passages and a paint-free process, secured with a tightening belt for enhanced stability. The concentric coil design features high-voltage windings with taps for precise voltage adjustments, made accessible through a tap changer mounted on the box cover, facilitating seamless voltage alterations following a power supply interruption.

Safety Protection Device: Our transformers, with capacities ranging from 30-2000kVA, are 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, augmenting safety and operational reliability.
