High strength insulation FRP bolt screw and nut
Fiberglass / FRP/ GRP bolts and nuts using high-strength fiberglass impregnated epoxy resin matrix at high temperature pultrusion.
After CNC process, grinding, special surface treatment made of insulated bolts and nuts.
Bolts and nuts have a special treatment by the surface, so that the bolts and nuts have good flexibility, excellent wear resistance, excellent resistance to voltage performance. Products applicable to transformers, reactors, special high-voltage converter valve, and other special high-voltage electrical appliances.
Product performance:
The product is made of fiberglass and epoxy resin mixed continuous pultrusion, which makes the product resistance to mechanical stress and mechanical tension are very good, the tensile strength of 1500MPa, far more than 45 steel casting tensile strength 570Mpa indicators. Electrical performance, voltage level for the 10kV - 1000kV voltage range. Corrosion resistance, high bending strength, not easy to bend, easy to use and so on.
Products allow long-term working temperature of 170-210 ℃ , product maximum short-circuit working temperature of 260 ℃ (time is less than 5 seconds).
The heat-resistant grade and the insulation grade of the product all reach H grade.
