High quality and excellent arc properties GPO-3 machined part used in electrical equipment
GPO-3 machined parts which were made of GPO-3 laminated sheet by CNC or punching tools , GPO-3 laminated sheet was made of fiberglass and polyester resin the fiberglass was impregnated in polyester resin with the aluminium hydroxide material and then press under the high temperature & pressure by machine. It is the F class material which required continuous working time meet to 20K hours .
This material machined parts with very nice arc property , it was application to every kinds of electrical equipment which has arc when running , it will remove the arc . In other way the machining precision can meet ISO2768-F according to the customer demand .It is so high precision in insulation industry . As soon as we know , higher precision which we can meet , better for the electrical products .
For example , the transformers requested high precision GPO-3 parts as the air gap . Normally , the higher precision tolerance , the better quality/performance of the products . Higher precision will increase leakproofness of transformer , the noise will be decreased , the more important is the insulation between phase will be better .
It is high precision tolerance part , it can meet tolerance ISO2768-F class
It has very good arc property when running ;
It is easily to machine by CNC machines .
It is green product , halogen free of it .
This material is widely used in every low and medium voltage electrical products .
GPO-3 laminated sheet with the performance on electrical properties such as arc resistance when it is working . So many electrical products have the arc while it is running . Arc will callused the insulation materials carbonized .once the material carbonized, it will be become semiconductor , so the properties will be effected .
For the machining properties , it can be grinded and machined according to ISO2768-F or more precision on the tolerance . With the technology development and requirements higher and higher , more and more components will be requested higher precision on the tolerance , whole electric equipment will be more and more precision . it will help the properties improvement . such as decrease noise , increase insulation between phases etc. The machined parts/plates are widely used in transformer/Switch cabinet/uninterruptible power supply , etc.
Further more , excellent insulation properties /mechanical properties of this material , so more and more electrical equipment manufacturers use it instead of other material as the plate , bracket , busbar , Cable clamp etc.
