You may have a 1500kVA alternator or a small electric fan motor at AltTech  we pride oursleves in offering what we feel to be an unmatched level of service and quality.

 

If a wound component has failed or degraded to such a degree where reliability cannot be guaranteed we will carry out a rewind to that component. Connection and winding configurations are logged and the wound cores are heated in  our ovens in preparation for coil extraction. Following extraction, removal of insulation materials and inspection the cores are ready for rewind, we insulated our cores  and windings with high quality insulation materials suited to the components requirements. Following completion the newly wound components are subjected to a series of electrical tests.

 

Components can then be impregnated via a double dip and cure or if superior resin and impregnation performance is required the wound component might undergo Vacuum Pressure Impregnation (VPI) and rotary cure or cure in our vacuum oven, on ventilated machines or exposed wound components an additional winding overcoat is selected and applied offering further protection from  environmental contaminants.

 

If re-machining or manufacture of new components is required this is carried out off site by a trusted precision machinist and fabricator

 

Every machine that we receive for rewind and repair also undergoes our overhaul procedure, please click HERE to view our overhaul page
