Epoxy
glass fiber grid cloth is made of electrician no-alikal fiberglass yarn compiled
into various specifications of the mesh cloth, after heat drying dehydration,
then dipped in the unique mixture of epoxy resin, the temperature drops of
glue, hot drying curing.
It is widely used in packing pouring of dry type transformer, reactor
coil, as inner and outer cladding and layer insulation of wire coil, its epoxy
resin with pouring coil tightly together, grid cloth can enhance anti cracking
performance of pouring coil, as in reinforced concrete, it can prevent the
pouring coil due to the cold and hot effect and great electric coil sudden
short circuit caused by the outside coil insulation cracking, greatly improving
the whole mechanical strength of the coil; Used for layer insulation grid cloth
as main line between layers of insulation, can prevent the inside of the coil
craze, but also can improve casting diaphaneity, inpisibility, is an ideal alternative to glass
fiber tape, DMD
