Product Description

Introducing our cutting-edge energy-saving, energy-efficient, secondary-class oil-immersed transformers at Global Power Equipment (Xuzhou) Co., Ltd. Through rigorous research, application of innovative materials, and advanced technology, we have engineered a product that boasts reduced no-load loss and minimal noise. Our transformers exemplify the perfect fusion of independent innovation and technology integration, offering optimized and revolutionary core and coil structures.

Our oil-immersed transformers are designed to deliver unparalleled benefits. With superior heat dissipation capabilities, they ensure stable transformer operation. They offer exceptional insulation performance and reliability, making them a dependable choice. Additionally, their voltage adjustment flexibility caters to various electrical requirements, while their mature technology ensures cost-effectiveness.

Iron Core: Crafted from high permeability magnetic grain-oriented cold-rolled silicon steel sheets, the iron core represents a new leap in core design. Featuring a fully oblique jointed structure, the core section is multi-stepped, ensuring equal sections for both the iron yoke and the core. This innovative design enhances efficiency and performance.

Winding: Our windings utilize a corrugated oil passage and a no immersion paint process, secured with a tightening belt. They are concentric coils with high-voltage windings that include taps to meet specific voltage requirements, connected to the tap changer with a switch mounted on the box cover. Voltage adjustments can be made post power supply shutdown, ensuring adaptability and user convenience.

Safety Protection Device For transformers ranging from 30-2000kVA, we incorporate a pressure relief valve. Additionally, users can opt for a gas relay equipped with both alarm and trip terminals, offering enhanced safety and operational security.

Oil Temperature Measuring Device: Our transformers come with a tube holder for a glass thermometer, positioned at the top of the oil tank and extending into the oil by 120±10 mm. For transformers in the 1000-2000kVA range, an outdoor signal thermometer is included, ensuring precise temperature monitoring and operational safety.
