Yellow GPO-3 fiberglass Sheet /Yellow polyester sheet / Yellow upgm203 / Yellow HM 2471 / Yellow GP0-3
Product Introduction:
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.
Features
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
products: | electrical reactor/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. Main famous cooperative enterprises: Siemens,TBEA Co.,Ltd. |
