Engineering Excellence: Inside Aputon’s 1250kVA Transformer for the 15kV Grid

What makes a transformer truly 'compact' and 'robust'? At Guangzhou Aputon Electrical Co., Ltd., it is a combination of intelligent design, premium materials, and rigorous testing. Our Ethiopia Type 1250kVA 15kV Compact Transformer is a testament to this engineering philosophy, specifically tailored for the technical demands of the 15kV distribution networks.

At the heart of the unit lies a high-efficiency, oil-immersed transformer designed for a 50/60Hz frequency rating. The substation features a three-compartment architecture—HV, Transformer, and LV—each segregated by iron plates for enhanced safety. The HV side is rated for 15kV with a lightning impulse withstand voltage of up to 125kV, ensuring protection against grid surges . The enclosure, available in corrosion-resistant stainless steel or composite materials, carries an IP33 protection rating, safeguarding internal components from dust and water ingress.

Operating out of our headquarters in the industrial hub of Guangzhou, we leverage over a decade of collective expertise to deliver products that not only meet but exceed IEC standards. The 1250kVA model is equipped with an automatic exhaust device in the transformer compartment to regulate temperature, ensuring optimal performance and a long operational lifecycle . For engineers and project managers seeking a balance of power, density, and durability, Aputon remains the partner of choice.
