Application  

These cables are suitable for outdoor installation. Their performance is primarily intended for voice-frequency circuits. For example, they can be used as primary and secondary cables in local telephone networks, telecommunications systems, railways, and industrial units.

Structure  

• Conductor: Annealed solid copper.
• Insulation: High-density polyethylene compound in accordance with ASTM D1248.
• Pair twisting: The insulated conductors are twisted into pairs with standard color coding. The pairs are then concentrically stranded together.
• Cable core covering: Polyester tape applied longitudinally or helically with appropriate overlap over the twisted pairs.
• Screen: Aluminum foil applied longitudinally or helically with proper overlap, along with a tinned copper drain wire placed between the polyester tape and the aluminum foil.
• Sheath: High-density polyethylene compound in accordance with ASTM D1248. The sheath is typically black with UV resistance.

Standard  

• VDE 0816 or TCI (Telecommunication Company of Iran) specifications.
