Product Overview
The three-phase oil-immersed distribution transformers manufactured by our
company feature anew insulation structure in the core, which enhances short
circuit resistance; the core is made from high-quality cold-rolled silicon steel
laminations; the high-voltage windings are all constructed using high-quality
oxygen-free copper wire in a multi-layer circular configuration; and all
fasteners undergo special anti-loosening treatment.
The product is characterised by high efficiency and low losses, enabling
significant savings in electricity consumption and operating costs, with
notable social benefits; it is a high-techproduct promoted by the st
