Arc Resistant CTI 600 GPO3 Fiberglass Laminate Sheet
Arc resistance reach 180 second and reach CTI600 GPO3 glass fiber laminate sheet
GPO3 sheet is also called UPGM203 sheet (Unsaturated Polyester Glass Mat Plate). UPGM203 is IEC standard
and GPO-3 is NEMA grade. The main composite is polyester resin , glass fiber mat and filler material . It is kind of rigid plate insulating material, made of alkali-free fiberglass mat impregnated with unsaturated polyester resin, adding relevant chemical agents in high temperature and pressing to rigid plate.
This material with very nice properties on mechanical , electrical and low water absorption , because of glass fiber with high strength on mechanical and unsaturated polyester resin with very nice electrical , such as high tensile strength , bending strength , impact strength and compression strength of properties on mechanical ; excellent arc resistance , CTI and break down resistance voltage ; very low water absorption due to filler material is calcium carbonate , UL 94-V0 due to the calcium carbonate , it is halogen-free which is environmental protection material .
Features of the material
a.Nice resistance Water absorption rate , the value less than 0.5%
b.High strength of bending , tensile and compression
c.Excellent fire resistance , it can meet UL94-V0
d.Great heat resistance class , long working temperature can meet F class , 155℃
e.CTI meet CTI600
f.Nice arc resistance , it meets more than 180 seconds , not easy to carbonization

What is application of GPO3 ?
As mentioned so much excellent properties on electrical , mechanical , heat resistance , fire resistance and low water absorption of GPO-3 material , this material is more and more widely used in the low and medium voltage electrical industries , such as photovoltaic power generation ( for example inverter cabinet ) , rail transportation (for example battery box ) , power generation, wind energy, power transmission and distribution (such as bottom and top cover in transformer) , metallurgy, petrochemical, public transportation and other fields.
It always made into insulating structural parts as follow products:
1.phase and end barriers,
2.insulating supports,
3.bus bar supports,
4.mounting panels in switch-gear,
5. slot wedge in switch cabinet,
6.motor
7. top and bottom cover in small transformer
8. combtype bracket in dry transformer
9. frame breaker
10. arc extinction plate and safety plate in breaker
