CALCINED KAOLIN FOR CABLE
(GB-CK90)
1. Benefits and Application
GB-CK90 is produced from highly refined kaolin by heating at
temperature above 1000℃During calcination, chemical,morphological
and mineralogical changes occur.
GB-CK90 imparts excellent electrical insulation properties to low
and medium voltage power cables.
