Detailed Selling Lead Description

Copper conductor solid PE Insulated coated Al Shielded Selfsupport Local Telephone Cable. Solid insulated filled cables are designed for duct use in local telephone network.
Flooding the core and outer surface of the core tape. With petrolatum prevents the entrance and migration of water and provides corrosion protection. At the environmental temperature of -30 to 60 centigrade, both the mechanical and electrical properties of the cable remain unchanged.
Conductor: Annealed bare copper, sizes  0.50, 0.60, 0.70, 0.90mm
Insulation:High density polyethylene medium density polyethylene, color coded in accordance with standard telephone industry code.
Twisted Pairs: Individual conductors twisted into pairs with varying lay length and with specified color combinations to provide pair identification.
Shield: A corrugated (or non-corrugated) AL tape with both sides plastic coated is applied to longitudinally wrap the core covering with two edges overlapped overlap seam sealed.
Jacket: Black low mid or high density polyethylene, PVC , fire-retardant PE or PE
