Product Description

Step Down Transformer for Electrical Systems

Our Step Down Transformer for Electrical Systems is an energy-saving marvel. This secondary-class oil-immersed transformer, a product of Global Power Equipment (Xuzhou) Co., Ltd, is the result of extensive research, innovative material application, and cutting-edge technology. Through the meticulous optimization and innovative design of the core and coil structure, we have significantly reduced no-load loss and noise, creating a self-developed product that stands out in efficiency and performance.

Oil-immersed transformers are renowned for their numerous advantages, making them an excellent choice for various applications. They offer exceptional heat dissipation capabilities, ensuring stable operation under high loads. The superior insulation performance guarantees high reliability and safety. Additionally, these transformers allow for easy voltage adjustments to meet different power requirements, all while being cost-effective due to their mature technology.

Iron Core: The iron core is crafted from high-permeability, grain-oriented cold-rolled silicon steel sheets. This innovative type of core features a fully oblique joint construction with a multi-stepped cross-section. Both the iron yoke and the core have equal sections, enhancing the efficiency and performance of the transformer.

Winding: Our windings utilize a corrugated oil passage design and do not require an immersion paint process, ensuring superior durability. The concentric coil windings are secured with tightening belts, and the high-voltage windings are equipped with taps to meet specific voltage requirements. These taps are connected to a tap changer, mounted on the box cover, allowing for voltage adjustments when the power supply is cut off.

Safety protection device For optimal safety, our 30-2000kVA transformers are equipped with a pressure relief valve. Additionally, a gas relay with alarm and trip terminals can be installed according to user requirements, offering enhanced protection and reliability.

Oil temperature measuring device: Our transformers come with a glass thermometer tube holder, positioned at the top of the oil tank and projecting into the oil by 120±10 mm. For 1000-2000kVA transformers, we provide an outdoor signal thermometer, ensuring accurate and reliable temperature monitoring.
