Product Description

Product introduction

Introducing our advanced three-phase oil-immersed power transformers, designed with a rated voltage range of 10-35kV. These remarkable transformers are the ideal solution for industries such as petroleum, metallurgy, chemical, textile, and light industry, especially those operating in high dust concentration environments. Crafted to meet the exacting demands of diverse enterprises, our transformers ensure superior performance and unwavering reliability, making them indispensable for your power infrastructure.
Capacity Range 30-2500kVA

Engineered for excellence, our transformer stands out with its exceptional high efficiency, minimal energy loss, and impressively low noise levels. It features brilliant internal heat dissipation and robust anti-short circuit capabilities. With minimal no-load and load loss, this transformer guarantees reliable operation, an extended lifespan, and a maintenance-free experience, establishing itself as a steadfast ally for your power needs.

This energy-saving, energy-efficient secondary-class oil-immersed transformer epitomizes our company's unwavering commitment to innovation. By harnessing new materials, state-of-the-art technologies, and an ingenious combination of independent innovation with technology introduction, we have remarkably optimized and transformed the core and coil structures. This breakthrough significantly reduces no-load loss and noise, highlighting the success of our ingeniously self-developed products.

 

Oil-immersed transformers deliver a plethora of benefits, boasting superior heat dissipation capabilities that ensure stable and consistent operation. Known for their outstanding insulation and high reliability, these transformers offer easy voltage adjustments, catering to a wide array of electrical needs. Their matured technology and cost-effectiveness render them an exceptional choice for diverse applications.

Iron Core: The core is a masterpiece, crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, representing a new era of iron cores. The full oblique jointed iron core, with its multi-stepped section design, ensures flawless uniformity across the iron yoke and core, elevating both efficiency and performance to new heights.

Winding: Our windings are an epitome of innovation, incorporating corrugated oil passages with a no immersion paint process, firmly secured with a tightening belt for maximum stability. The concentric coil design features high-voltage windings with taps for precise voltage adjustments, effortlessly accessible via a tap changer mounted on the box cover, facilitating seamless tap voltage changes post power supply interruption.

Safety Protection Device: Our transformers, ranging from 30-2000kVA, are fortified with essential safety features such as a pressure relief valve. Moreover, a gas relay with alarm and trip terminals can be installed in accordance with user requirements, augmenting safety and operational integrity.

Apply	Mines, oil fields, subways, power plants, schools, hospitals, commercial centers, high-rise buildings
Installation height	The altitude does exceed 1000m
