Description:
Epoxy glass fiber winding tube is made of fiberglass yarns impregnated with an insulating colloidal compound of epoxy resin and other resins, and is formed by hot-baking by wet-rolling. This product has a high temperature resistance class and reaches class H, with good electrical properties. Mechanical properties, low dielectric consumption, no deformation, no delamination, chemical resistance (resistant to SF6), etc.
Epoxy glass fiber winding tube is widely used in the main insulation of H-type dry-type transformers, on-load tap-changers, reactors, arresters, SF6 transformers and other products.
Main Features and Test Items:
1. Reliable electrical insulation property:
All the epoxy resin fiberglass tube at each voltage class produced by our company are subject to lightning impulse type tests according to Chinese National Standards. Routine tests like withstand voltage and partial discharge tests are performed before each epoxy fiberglass tube leaves factory so as to ensure stable and reliable electrical insulation property of products during service.
2. Reliable mechanical performance:
All the epoxy resin fiberglass tubes at each voltage class produced by our company are subject to 10000 opening and closing life tests. For each heat of epoxy resin fiberglass tube products, routine destructive tensile tests are performed for test objects, and also torsion tests and other mechanical performance tests can be carried out as necessary.
3. Reliable thermal deformation resistance:
For each heat of epoxy resin fiberglass tubes, DSC differential thermal analysis is performed to ensure reliable thermal deformation resistance of products.
4. Reliable internal soundness:
Each epoxy resin fiberglass tube is subject to routine X-ray non-destructive testing to guarantee absence of internal defects so that sound internal structure can be ensured for reliable use.
5. High external surface quality
The epoxy resin fiberglass tube produced by our company are of aesthetically pleasing internal and external surfaces, which are free from special coatings or finishes.
Epoxy resin fiber glass winding tubes in various specifications (diameter ranges from 4 to 1000 mm) can be produced in accordance with users' requirements, meanwhile, they can be processed according to different requirements (notch, turning, wiring etc.).
Application:
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.
