Description:

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.

Our epoxy resin fiberglass tubes are produced by adopting the vacuum casting technology manufactured in a high class purifying room, which guarantees superior performance and reliable quality of products. They are widely applied in high voltage circuit breakers, isolation switches, earthing switches and other electricity equipment with the voltage level from 35kV to 1100kV. They are also widely used for kinds of pipeline system, such as waste line, petroleum chemical lines, pipeline connected to the tank or other systems. Among more than 200,000 sets in operation, no quality problem has been found, winning favorable comments from customers at home and abroad.

 

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.

  1. 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.

  1. 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.

  1. 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.

  1. 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.
