Stator Bars

High-voltage, insulated copper bars used in the stator cores of large generators and motors to conduct main phase current.

• Construction & Materials: Straight and Roebel transpositions up to 540°. Resin-impregnated and overwrapped with mica-glass insulation. Shapes are precisely machined to slot and evolute requirements
• Technical Spec: Resin rich and global VPI insulation systems.Up to 410MW with insulated section 40mm x 140mm; Up to Class F temperature rise.
• Applications: Turbo generators, hydroelectric alternators, nuclear and fossil fuel generators, and high-capacity synchronous motors.
• Manufacturing & QC: CNC shaping; End to end taped with PC controled six axies tape machines, program controlled hotpress processes, tested with surge voltage, partial discharge, tan delta, and endurance methods.
