Insulation Crepe Paper

Crepe paper is made of elastic cable paper; Base material thickness: 0.05 0.08 0.13mm. Coventional Thickness::20 25 30 40mm, and also can be customized according to customer’s demands.

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.
This Crepe Paper can be supplied in Jumbo rolls of 1000mm (1 meter) width or in slitted pads as per customer requirements.
