Product Details

Fiberglass covered wire

Fiberglass covered wire is a kind of winding wire,first, the ectrical round aluminum rod is extruded or drawed

into high quality aluminium conductor,then it is wrapped by the fiberglass,then it is insulated by the varnish and dried.They are mainly used in dry-type transformers,motors and generators coil.
