CTP APL AS 40/50 pair
StandardsNational : ABNT NBR 9889
Construction: Soft annealed bare copper conductor, 0.40 , 0.50 , 0.65 or 0.90mm nominal diameter, insulated with colored solid polyethylene. The insulated conductors are twisted in pairs and assembled in layers and/or groups to form a substantially cylindrical core. The cable core is bound with binder threads and/or a binder polyester tape and shielded by a flat polyethylene-clad aluminium tape (LAP - Laminated Aluminium Polyethylene), longitudinally applied. A black polyethylene jacket is extruded over the shield and the steel messenger. Under the jacket, two ripcords are applied to ease the jacket removal. Service pairs may be available, according to the Brazilian Standard ABNT/NBR 9889, upon customer request.
Application: These cables are intended for analogical or digital signal transmissions.
Installation: Aerial self-supported.
