Description

The single-phase, two-phase and three-phase air-core inductors manufactured by GTS Elettrotecnica offer an extremely reliable and versatile technical solution, ideal for industrial applications where high performance, installation flexibility and the absence of ferromagnetic materials in the magnetic circuit are required.

Thanks to decades of experience in the sector, GTS Elettrotecnica is able to design and manufacture highly precise and robust air-core inductors, suitable for heavy-duty use and demanding operating conditions. The windings are made on fiberglass supports, available in two configurations: lattice frame or form. Both solutions ensure mechanical stability and resistance to environmental agents, and are generally mounted on insulators to ensure high electrical safety and simplified installation. Resin impregnation and its curing complete the production process.

These inductors are ideal for use in filtering, compensation and current-limiting circuits, and are particularly effective in environments where it is necessary to avoid magnetic saturation and minimize hysteresis losses. The air-core construction, without a ferromagnetic core, ensures linear operation even in the presence of high currents.

Each inductor can be customized according to the technical specifications required by the customer, both in terms of dimensions and inductance values, connections and accessories.

Compliant with the strictest standards for insulation and electrical safety, GTS Elettrotecnica’s air-core inductors are the ideal choice for those seeking high-performance, long-lasting solutions designed to measure for every type of system.
