Product Description


High Strength Polyester Resin Sheet With UL Certificate Use In Transformer


Pruduction introduction :

GPO-3 laminated sheet was made of fiberglass and polyester resin , the fiberglass was impregnated in polyester resin and then press under the high temperature by machine . This material has the very excellent machining properties , it can be cut into smaller sheet , grinded surface , drilled the holes and punched by reciprocating saw , CNC (CNC engraving machines) and punching machines .it can be machined into complex assembly parts by every machines according to the drawings from clients , that is means it is the customized product .The material can be machined by precision machining by CNC machines , the machining tolerance can meet ISO2768-F class , it will more convenience to assemble .


To meet the requirement from Europe and America ,the material has ROHS/REACH/UL/SGS and other requirements , it has been exporting to more than 30 countries all over the world , some of clients are the top500 in the world .

UPS is the uninterrupted power supply which is connected to the host by the battery ,converts the direct current into the system equipment of the AC by module circuit of the main engine inverter. When the market input is normal,UPS supplies the AC to the load after voltage stabilization .At this time, UPS is an AC voltage regulator, and it also charges the battery inside the machine;
When mains supply interruption (power outage), UPS use the battery's direct current energy to continue supply 220V alternating current to the load immediately through the inverter switching conversion method ,it makes the load keep working and protect the software and hardware from being damaged. UPS devices usually provide protection against voltage too high or too low .The flame retardant requirement for insulating materials is V0, high strength and temperature resistance , The commonly materials used in UPS is HC-GPO3
UPS are divided into:prepared UPS ,Online UPS,On line interactive UPS,The working principle of UPS is use the AC to charge the battery.than use the battery to supply the power for inverter cabinet,in order to supply power automaticly when the AC fails.
GPO-3 sheet,PC are mainly used as Protective cover sheet , the structures plate,battery box which will improve the safety and durability of UPS.
