With the imported super-high purity electric homopolymerize PP resin , it is formed through biaxial stretching, which has features of good uniformity of roughness film, easy rolling and high operation field strength; meanwhile, as for the corona treatment to the roughness film, the wrapped capacitor has small dielectric loss and high insulation resistance.
It can be used in rough film capacitor including the manufacturing of medium and high pressure capacitor and capacitor transformer etc. in the reactive power compensation, equalizing, filtering, coupling of the transmission and transforming system; also due to the corona treatment to the rough film, it can be used for metalized film capacitor such as the DC support and filtering capacitor etc.
3.Representing method of thickness
The nominal value can use the central value of the thin film thickness (integer value such as 3, 10, 15, etc) plus the mantissa (one decimal place) or the their codes. We use Weight method (WMV) to value the MPP film thickness; and that of RPP/RRPP/MRPP film are valued through Mechanism method (MMV) (Ten-layer method)
