Butler Winding has an engineer on staff who is experienced in transformer and inductor design. If customer personnel need technical advice, they can telephone Butler Winding and ask to speak to engineering. Schedules permitting, our engineer may design transformers for our customer. As of present date, simple design work is usually done (not always) at no charge as a courtesy to our customers. A more extensive effort may warrant and incur a charge to the customer for the service. Schedules permitting, our engineering may be available for an hourly or daily fee contracted through Butler Winding.
