    ESPA LLC manufactures magnetic components from 40 years. The entire production cycle is carried out in our own plant, thus ensuring high quality standards through the control of the entire production chain. Each single product is totally customizable and evaluable before starting production through computer design support, on-line sharing, testing phases and the development of 3D CAD / CAM simulation.

  • ESPA’s philosophy

    The ESPA’s philosophy aims to support its clients from the conceptual design phase to the final realization of the product. This strengthens and guarantees to optimize each component according to the functional and constructive specifications to satisfy. High quality standards, long experience of realization of each component and the total design flexibility qualify ESPA as a producer of excellence in the sector.

Products and materials

ESPA manufactures specific magnetic components for low and medium voltage dry at low voltage from 100 VA to 1000 kVA for single-phase and up to 1800 kVA for three-phase.
The main materials used for the realization of the windings are mainly aluminium and copper, in band, strip and wire.
Insulation materials include Nomex®, Nomex® 410, Nomex® Mylar Nomex®, Dacron Mylar Dacron and glass fibres materials.
Each product is protected with a final treatment of tropicalization and epoxy polyester resins
The design department evaluates and determines the use of the best technological and production materials and combine these to get the best results in terms of volume and noise reduction.
