Electrical Grade Insulation Crepe Kraft Paper
EGI Crepe Kraft Paper is the most important and critical insulation component in any transformer. Our strict quality check and use of branded raw materials ensure that our manufactured products stand out against others in terms of physical feel as well as performance.
All thicknesses of our crepe papers are regularly tested at ERDA, Vadodara, India as per IEC grade requirements.
Applications:
Transformers: This crepe paper is used as an insulation in manufacture of oil cooled Power Transformers, Current Transformers, Distribution Transformers, Instruments Transformers and Rectifiers, Renewables, Traction Transformers, Bushings, etc. as leads and shields, covering crossover, transposition, joints in windings. This crepe paper has 300% more strength in mechanical and cross mechanical directions and hence is more resistant to breakage. It can also take various shapes of the surface being insulated. Crepe paper also has greater surface area which helps to retain more oil and hence lowers the working temperature of the transformer.
Crepe Paper Covered Copper Conductors for Transformers: This Crepe Paper is used to cover copper conductors having various cross-sectional shapes. This paper is used to cover copper conductors bent at an angle of 180 DEGREES. As a result, this insulation will not break or tear or crack compared to plain kraft paper insulation.
Availability:
The base kraft paper thicknesses on which creping is done are 1.5 mils (40microns), 2.0 mils (50 microns), 2.5 mils (65 microns), 3.0 mils (75 microns), 4.0 mils (100 microns), 5.0 mils (125 microns), 6.0 mils (150 Microns). Thickness above 6.0 mils can be provided as per customer's requirement. The elongation can be supplied as per specification from 10 % up to 300 %.
This Crepe Paper can be supplied in Jumbo rolls of 1000mm (1 meter) width or in slitted pads as per customer requirements.
