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