Product Description


Excellent Insulation Properties Of GPO-3 Machined Part To Every Electrical Cabinate


Product Introduction:

Polyester resin coated on the glass fiber mat named GPO-3 materials, it has the filler material named aluminium hydroxide which was used to fire resistant , and then press under the high temperature & pressure by machine. The material inclusive laminated sheet , pultrusion profiles and molded parts . The machined part was made of GPO-3 laminated sheet .

At present , the sheet size which we can supply is 1000*1200mm if the thickness from 0.5-3mm ; if the thickness more than 3mm , we can supply 1230*2100mm to machine the big size parts .

This material machined parts with very nice arc property and insulation property , it was application to every kinds of electrical equipment which has arc when running , it will clean 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 , it will be better for the electrical products .

For example , the transformers requested high precision GPO-3 parts as the air gap and insulation struck . As soon as we know , 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 .

Feature of this material :

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 .

It is the F class heat resistant , the temperature is 155℃

Application of material :


GPO-3 laminated sheet with the performance on electrical properties such as arc resistance while the electric equipment 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 , carbonized will be decrease the insulation property and even damage the whole equipment .

This material have the good properties on machining , 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 improve the properties , 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.
