Varnish and resin Specifications:
Insulation Resin
The high quality bi-component insulation resin used from Mecc Alte, is a polyester specially developed
to be used in vacuum impregnation or dip/ and trickle machines. It does have superior bond strength
characteristics, high chemical and moisture resistance and is suitable for uses up to 212° C.
Grey Varnish
EG43 The EG43 grey varnish, is an high temperature insulating
enamel that forms a tough and flexible film, with excellent moisture
and chemical protection. It is water and oil proof, and also protects
windings from abrasion. It is applied spraying an over coating layer
over the impregnated winding, or dipping the stator in a varnish
barrel for superior treatments.
Black Severe Environment Protection
The black severe environment protection is a system that makes Mecc Alte special. It is the ultimate
winding treatment that offers truly superior performances when the
environment is severe, or the application very demanding. It is a
protection treatment used to replace epoxies and silicones winding
encapsulation. The black protection cures to a tough, resilient, black
coating that seals the copper against moisture and chemical
attacks. Due to its encapsulation capability and durability, is also
extremely resistant to the particle abrasion as it adsorbs the
impacts. Moreover, this leads to a long trouble less life protection,
as the protection layer follows elastically the thermal expansion
cycles of the windings from the cold to the hot condition and vice
versa without forming any cracks.
No alternator derating with WTP.
16.2 ACH – Anti-Condensation Heater
ACH option consist in an alternator equipped with heater in the windings and is used to prevent formation
of condensation in the alternator’s windings.
Anti-condensation heaters are designed to raise the temperature of the windings above the temperature of
the surrounding material so that the condensation will not form on the windings.
It is recommended that anti-condensation heaters are fitted to all generators that are left switched off for
any period of time. This is particularly important in applications where high humidity is a significant problem.
Compatibility:
All genset.
Incompatibility: none.
