A protection system capable of withstanding the harm caused by the various different types of attack encountered. In severe environmental conditions, the traditional polyester varnish applied to the windings can be subject to ageing or premature corrosion. In such cases, the machine protection should be reinforced.

Typically these are special resins that act as a physical barrier to humidity, salt or aggressive chemicals.

Generally the resin in the most special impregnations covers the stator and the rotor windings

KEEP IN MIND

• The standard Onis Visa product already has a high level of impregnation
• Many times, due to special or "extreme" environmental conditions (extreme temperatures, humidity, dust, etc.), alternators with special winding impregnation may be required.
