Flexible mineral-insulated cable for power circuits
RTTZ is a flexible copper conductor Mineral Insulated Fire Resistant Cable with mica tape insulation and a corrugated copper sheath. The covered RTTZ power-cable version is rated 0.6/1 kV.
Mica tape insulation under a corrugated copper sheath
The visible cutaway shows stranded copper conductors, a mica tape insulation layer and an outer corrugated copper sheath. The corrugated metal covering distinguishes this flexible construction from rigid smooth copper sheathed mineral-insulated cable.
Specify RTTZ and the required core arrangement on the purchase order. Request the applicable documents for the ordered cable dimensions.
