Product Application
Insulation Fiberglass Filament Winding TaperTubes /Corn Tube Widely used in oil-immersed transformer, H class dry type transformer, railway locomotive transformer on-load tap-changer, reactor, lightning arrester, SF6 transformers, such as high pressure test device main insulation products.
Epoxy fiberglass winding tube is made of fiberglass yarn impregnated with epoxy resin etc, and then rolled in wet method, and then dried and consolidated. Its heat resistance level can be up to H level, and it also has excellent electrical and mechanical properties, low dielectrical loss, no deformation, chemical resistant etc. It can be used as main insulator on H grade dry type transformers, load tap changer, reactor, lightning protector, SF6 Inductor etc.
The main use is for arresters (sleeves), flow limited fuse boxes, link sticks, earth sticks and some high voltage electric equipment.applications requiring good insulation resistance, arc resistance, and dielectric strength. Recommended for its dimensional stability under varying humidity condition. sush as high voltage insulators and fuses tubes,CMOA , spacers, and coil forms for electrical equipment,Antennas.Battery ,casings ,Bearings and Collars,Bushings,Cryogenics,Equipment and Tool Handles.Impeder tubes.Pressure tubing,Structural tubing,Water and wastewater treatment components etc.
