Another major component manufactured from crepe paper is flexible crepe paper tubes. These tubes are used as sleeves for interconnection of terminals. This is a time saving product, extremely easy to use. These flexible crepe paper tubes have higher rate of absorption of oil thus ensuring higher di-electric strength compared to conventional srbp tubes.
Features: made of electrical grade insulation crepe kraft paper. Direction of creping is transverse. Only the edge of outer layer is glued. These tubes have extremely good compatibility with liquid di-electrics. Class “a” insulation (105oc). The tube retains maximum oil due to use of crepe paper. These tubes can bend under extreme conditions without collapsing.
Availability: i.D. Starting from 2 mm. O.D./wall thickness as per specification. Standard length is 1000mm. Any length up to 2000mm available as per customer specification. Tolerances: i.D. +0.5mm. O.D. +1.0mm
As per requirement
Semi conducting black crepe paper is used by transformer industries as well as cable covering industries. The main use of this material is to ground the leakage of current.
Availability: Available in roll form of maximum width of 20” or in slit widths.
as per req.
This product, also known as pmp, is used in ct/cvt transformers and cable industries which removes static voltage field when heavy voltages are introduced.
Types : perforated / non perforated and crepe / plain
Availability: available in roll form 50 meters of 22mm and 25mm slit widths. Material is wound on cores comfortable to be used by hand. Total thickness: 180 microns (standard). Required thickness combinations can be supplied.
As per req
Application of crepe paper:
Transformers:
This crepe paper is used as an insulation in manufacture of oil cooled transformers, current transformers of types imb, ct, cvt, etc. As leads and shields. 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 180o. 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 1.5mil (40microns), 2.0mil (50 microns), 2.5mil (65 microns), 3.0mil (75 microns), 4mil (100 microns), 5.0mil (125 microns).
Thickness above 5 mil 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.
