OVERVIEW OF PROTECTION SYSTEMS FOR ALTERNATOR

SYSTEM 2


System 2 is used when the alternator environment is very likely to be damp. This system primarily concerns the windings, which are given a special treatment. It should be noted that this treatment protects the windings effectively against all 


This flexible coating is only applied to the lower parts of the stator. Feedback from the field has shown this area to be the most vulnerable to attack, as it is here that deposits and condensation tend to concentrate. Moreover, since the thickness of the coating causes the winding temperature to rise, it would be counter-productive from a longevity point of view to apply it all around the stator

FROM SYSTEM 2 UPWARDS, WE OFFER A COMPLETE PROTECTION SYSTEM FOR ALL TYPES OF WINDING


The exciter stator (field) is also covered in a two-part flexible epoxy resin. System 2 is suitable for use in an atmosphere with

humidity higher than 95%, however the ambient temperature should not exceed 40°C.



SYSTEM 4

Protection system 4 uses the same winding protection as system 2 and boosts the protection level of the mechanical parts so as to offer increased resistance to hostile environments. Exposed parts of the alternator rotor shafts are protected against rust with a black coating that has been specially formulated to withstand saline mist.


System 4 is suitable for use in an atmosphere with humidity higher than 95% and an ambient temperature over 40°C.


System 6
This system has been specially designed for using machines in an extreme environment: exposure to sea spray, abrasive dust or corrosive air. In order to guarantee an optimal level of protection, the whole of the machine is specially treated with
the application of a double layer of high-resistance epoxy paint.This additional protection eliminates the risks associated

with premature ageing of the most exposed parts of the machine.
