Lighter Power Transformers from Bridgeport
Toroid power transformer.
Shelton, CT — Bridgeport Magnetics has introduced its new LW series of custom designed power and isolation transformers for 400Hz frequency operation up to 600VAC for applications onboard aircraft, in shipyards, seaborne and other marine applications.

Compared to conventional C-core transformer designs, the LW series typically offers a 50 percent weight reduction by optimizing the design with Copper Clad Aluminum (CCA) wire windings and low profile toroidal cores that utilize 4 mil (0.1mm) thick grain-oriented silicon steel.

The custom designed power and isolation transformers are available up to 10kVA power rating for single phase or 30kVA for three-phase systems. Other benefits include lower no-load losses, quiet operation and no hot spots as is the case with all toroidal core transformers. With in-house core production dimensions of OD and height are flexible to suit the customer's requirements. For three-phase systems, each phase is served by a separate transformer, allowing better weight distribution inside low profile cabinets; this provides an alternative to stacking the transformers on top of each other or vertically side by side.

Single-phase transformer weight ranges from 4.5 lbs (2 kilos) for 1000VA to 28 lbs (12.7 kilos) for 10kVA; three-phase system transformers range from 13.5 lbs (6 kilos) for 3kVA to 84 lbs (38 kilos) for 30kVA.
