Scope of Application
\nProduct 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.<\/p>\n

The 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 state.<\/p>\n

Scope of Application
\nThe BK series control transformers are suitable for use in circuits with a frequency of 50\u201360 Hz and a voltage up to 500 V. They
\nare typically used as control power supplies for general electrical equipment in machine tools and mechanical machinery, or as
\npower sources for local lighting and indicator light<\/p>\n
