BALAJICORK- Insulating Kraft Paper (IKP)
|
|
Insulation Kraft papers of the type having the required quality specifications for electrical insulation purposes are made entirely from imported virgin fibers. The high purity of the imported virgin fibers ensures that product is totally free from any impurities and conductive particle in particular. Insulation kart paper is available in roll form with a maximum width of 1500mm and widely used as electrical insulation wrap o aluminum and copper wire by conductors manufacturers, electrical insulation between layers of wound coils in electrical motors, in capacitors transformers and such electrical equipments. We offer these materials in nature brown finish in 2.0 mil, 2.5 mil, 3.0 mil, 4.0 mil, and 5.0mil . The material meets to IEC 60544‐3‐5 specification for electrical purposes.
