The Varnished Cambric cables are made in single and multi core designs either with fibrous braiding and flame proof or fire resistant finish or with the metallic or nonmetallic sheath with or without further protective covering. Varnished cambric is not sufficiently moisture resistant to be used in a wet environment without a continuous metallic covering and is suitable for operating temperatures from 70°C to 80°C. The dielectric loss of varnished cambric insulation is higher than of impregnated paper insulation. These cables are ideally suitable in hot and dry used such as in steel plant, foundries, rolling mills, furnaces, metallurgical plants and industrial substations. These are also suitable for the transmission of high voltage power over short distances.
