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 tube
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.).
