Copper telecommunication inside cable (CCP-LAP)
Feature
Copper telecommunication inside cables (CCP-LAP) type are used for primary and secondary distribution networks, (i.e., in the secondary network between cross-connection cabinets and the subscribers’ connections, in the primary network between the exchange and cross-connection cabinets) and produced for ducted underground installation with natural polyvinyl chloride (PVC) sheath it is suitable for tropical environmental conditions (from -10 °C to +60 °C ambient).
Description
- Up to 100 pairs following REA – PE 89 (USA), TCVN 8238:2009.
- Conductor size: 0.4mm; 0.5mm; 0.65mm; 0.9mm.
- Copper telecommunication inside cables type is designed by solid pure annealed copper conductor, high density polyethylene insulated, paired, ten or twenty-five pairs sub-unit type, polyester tape wrapped (PS tape), screened with aluminum moisture barrier and natural PVC sheathed, indoor type, primary and secondary local telephone cable.
