Yellow GPO-3 fiberglass Sheet /Yellow polyester sheet / Yellow upgm203 / Yellow HM 2471 / Yellow GP0-3
Yellow GPO-3 fiberglass Sheet is rigid laminated sheet made of heat pressing which composed of e-class glass-mat reinforced unsaturated polyester and inorganic filler binder.
our laminates also have superior consistency in thickness, punchability and property control. Add a high degree of quality and cost-ffectiveness.
These sheets are fiberglass reinforced thermoset polyester,They will not melt under heat and have excellent overall electrical properties .all grades are UL Recognized.
Electrical Insulation :All grades of GPO3 sheet have inherently good dielectrics. They are engineered to maximize the specific properties required for a wide range of electrical applications.
Flame Resistance :GPO3 sheet are UL-rated V-0. They belongs to halogen-free system that generates very low smoke and smoke toxicity in a fire situation.
Mechanical Strength :Our GPO3 sheet have stable mechanical strength wich won’t cracked when machining
Heat Resistance:Our GPO3 sheet have excellent property retention and dimensional stability at elevated temperatures. These laminates have UL temperature index ratings over 150℃

Yellow GPO-3 fiberglass Sheet used in the transformer
|materials:||Yellow GPO-3 fiberglass Sheet|
|Description:||The electric reactor is also called the inductor ,after the electric reactor is energized, the magnetic field can be generated in a certain space range which plays a protective role in the power transmission and distribution.The transformer utilize the electromagnetic induction to change the voltage of the alternating current, and it acts as an energy conversion process.
