Random Wound
Schulz Electric’s three environmentally qualified random-wound insulation systems meet NUREG-0588 CAT-I Requirements (IEEE 323-1974) and are designed for various motor applications.
Inside containment random-wound continuous duty EQ insulation*†
- 40-year qualified life @ 40-50°C ambient with a 80°C rise, 10-90% RH, 2193 load cycles
- Radiation TID: 1.05 x 108 rad
- LOCA/HELB test, peak temp: 419°F, 100% relative humidity, PWR chemical spray, 104 PSIG peak pressure
End-Use Applications: Inside-containment fan motors
Random-wound intermittent duty EQ insulation*†
- 20-year qualified life @ 50°C ambient with a 80°C rise, 0-90% RH, 1040 load cycles
- 8 OBEs to 6.67g, 1 SSE to 10g (5% damping)
- LOCA test, 425°F peak temperature, 77 PSIG pressure, PWR chemical and water spray, 100% humidity
End-Use Applications: Inside and Outside-Containment MOV Motors
Random-wound continuous duty radiation-only EQ insulation*†
- 20-year qualified life @ 50°C ambient with a 80°C rise, 0-90% RH
- 5.2 x 107 rad normal, 1.7 x 108 rad accident, 2.3 x 108 rad TID
- 8 OBEs to 6.67g, 1 SSE to 10g (5% damping)
End-Use Applications: Drywell Cooling Fan, Containment Cooling Fan, and Motors Outside of Containment
*One-year post accident operation.
