Croatia Semi-Insulated Conductors CCST for Public Procurement  20(24) kV

CCST AAAC 12/20 (24) kV

CCST is a round-wire, non-compacted, thermoplastic covered conductor. The All Aluminum Alloy Conductor, AAAC is longitudinally water blocked. All three layers are extruded in the same process. The UV-protected HDPE-jacket is both abrasion
and tracking resistant.

Conductor – AAAC
Extruded, longitudinal waterblocking layer
Extruded, inner semiconductive layer
Insulation of PE
Outer layer of UV-resistant HDPE

Minimum bending radius: 15 x diameter.
Lowest temperature for installation: -15°C.
Maximum continuous temperature: +70°C.
