Design

A twisted ribbon core, impregnated with a special compound, having a fixed non-magnetic gap with a textolite insert, is placed in a container made of a non-combustible plastic. The container, which has a rigid structure and rounded edges, provides reliable mechanical protection of the magnetic circuit from external influences while maintaining its properties, as well as the ability to apply winding with a wire of large diameter.

Fire safety of the core and its constituent elements is ensured by the use of non-flammable and non-flammable materials.
