Mica insulator is an entirely mineral material that basically
consists of mica and glass- a binding agent that can be vitrified
by fusion. These elements are mixed and combined in powder form,
and then heated under pressure: the particles of glass when they
melt, cover the flakes of mica to form a compact and hard mass.
Glass-mica compounds hold a privileged position among the wide
variety of insulators offered to the electrical industry. They are
positioned by their temperature of use between plastics and
ceramics but they possess the ability to be moulded and to be
machined like the former but with the hardness and indestructible
qualities of the latter. Mica insulator adds a series of physical
and chemical properties to these practical advantages which makes
it an entirely exceptional insulator.
Mica insulators can be used for high speed train break resistor, as
ideal insulation materials.
