Our G12 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.
1.G12 Filament wound composite products made of glass fibers and epoxy resin have besides very good mechanical properties and fair temperature resistance also excellent electroinsulative properties.
2.it is a glass fabric base rolled tube bonded with a epoxy resin. This grade has heat resistant properties .
3.It possesses excellent electrical properties, and low water absorption when exposed to high humidity conditions.
4.Product explanation and use: The sleeve of epoxy resin fiberglass forms in the process which nonalkali fiberglass dipped epoxy resin liquor twists along tubing axis with 50-60 degree ,,
5.The product is widely used in the fusion tubing of high/low pressure flow limited fuse box and other electrical equipment.
6.The product can be sawed, cut, bored, and roped silk.
7.All this machinability does not cause flaws like crackle, bedded structure, desquamation etc.
8.The color of the product is red, white, light yellow and light green.
9.Anti-bend intensity no less than 200mPa.
10.The electric intensity for plumb layer exceeds 8KV/mm. All specification can be made-to-order.
Epoxy resin fiberglass filament wound tubes are made of non-stop fiber wet winding. It is specially developed for high-voltage electrical equipment structural parts such as reactor, lightning arrester, fuse, transformer, on load tap changer, transformer,etc. the product performance parameters meet the requirements of IEC standards,the product is leading in China.
