Northlake Engineering / custom transformers and assemblies

World-class engineering expertise is at the heart of Northlake’s success. Their engineers have the skill and experience to develop high-quality component designs, linear power supplies, power distribution units and power conditioners. Northlake’s design versatility is extraordinary—with end products that are small and detailed or large and complex. Their integral planning process will strategically consider cost and functionality and they are always eager to discuss any special requirements and enjoy partnering closely with their customers to produce the most effective design solutions.

Northlake Engineering’s sample and prototype policy

Due to Northlake Engineering being a 100% custom manufacturer of power transformers, coils and power assemblies and subassemblies, a sharing of the costs (material and labor) with the customer is sometimes requested.  Based upon the complexity of the designs and availability of raw material and components, Northlake tries to ship samples and prototypes within 2-4 weeks after receipt of request. 

With the very high costs for electrical-grade steel and copper, the critical materials utilized in power transformer and coil designs, what is Northlake doing to help mitigate these increases?

Wherever and whenever they can, Northlake’s design engineers specify the least amount of copper and lowest cost electrical-grade steel as possible while meeting or exceeding the customers’ required electrical characteristics be it a custom transformer or coil or custom power assembly.  When material surcharges are in effect, Northlake strives to manage these costs as a “pass through” whereby no markup is added to these charges.
