Glass/ Micanite Folium
General Details
Ruby Mica® Glass / Micanite Folium is a lamination of two layers of fine muscovite mica splitting with glass cloth, bonded together using a B-stage epoxy resin. The resin, when subjected to heat and pressure, yields a cured rigid insulation bearing high mechanical and dielectrical strength.
APPLICATION
End-winding on high-voltage rotating machines. when fully-cured to form rigid laminates they provide excellent corona-resistant insulation, capable of withstanding high-voltage partial discharges.
AVAILABILITY
Folium:
Length : 50 m
Width : 1000 mm
PACKING
Tapes are packed in airtight robust boxes protecting them from dirt, dust and moisture.The packaging also ensures safe transit and storage.
STORAGE
3 months at ≤20°C
