Ultra-Sealed Winding The process was developed to create total electric motor protection against moisture, prevent corrosion, improve heat transfer from the coils to the frame and enhance winding rigidity; The Ultra-Sealed Winding procedure involves insulating and sealing the winding through a mechanical and pressure process using a patented resin; An Ultra-Sealed Winding should not be confused with an encapsulated winding; Encapsulation only involves coating the coil ends, but when Ultra-Sealed, the coils are completely impregnated and sealed within high molecular weight thermoset polymer resin; There are two major advantages over traditional insulation methods; One is total protection against moisture; During in-house tests, windings have been completely submerged in synthetic cutting fluid for as much as 2 months without faulting to ground; The second advantage is more efficient cooling; The high molecular weight thermoset polymer resin is approximately 40 times more efficient at heat transfer than air
