Product Description

Three Phase Step Down Electrical Transformer

Our energy-saving, secondary-class oil-immersed transformer is a marvel of engineering, developed through tireless research and the application of innovative materials and cutting-edge technologies. By optimizing and ingeniously designing the core and coil structure, we've significantly reduced no-load loss and noise. This transformer is a testament to Global Power Equipment (Xuzhou) Co., Ltd's commitment to pioneering advancements.

Oil-immersed transformers come packed with numerous benefits. They boast superior heat dissipation capabilities, ensuring stable and reliable operation. These transformers also feature outstanding insulation and high reliability. With easy voltage adjustments to meet diverse electrical demands, they combine mature technology with cost-efficiency, making them a wise investment.

Iron Core: Crafted from high-permeability magnetic grain-oriented cold-rolled silicon steel sheets, the core is an advanced type of iron core. It features a fully oblique jointed design with a multi-stepped section. The iron yoke and core sections are meticulously matched, ensuring optimal performance.

Winding: Our windings incorporate a corrugated oil passage design, eliminating the need for immersion painting. Tightly bound with a robust tightening belt, the windings form concentric coils. The high-voltage winding includes taps for various voltage requirements, connected to a tap changer mounted on the box cover for easy voltage modifications after power cutoff.

Safety protection device Our transformers, ranging from 30-2000kVA, come equipped with a pressure relief valve. Additionally, a gas relay fitted with alarm and trip terminals can be installed as per user specifications for enhanced safety.

Oil temperature measuring device: Equipped with a glass thermometer tube holder, the device is installed at the top of the oil tank, extending 120±10 mm into the oil. For transformers in the 1000-2000kVA range, an outdoor signal thermometer is provided for precise temperature monitoring.
