Drop Wire UTP Unshielded Twisted Pair Messenger Telephone Cable

Product Description

Product Description Drop Wire CableApplicationThe cables are designed for use as connection between central offices. The cables are suitable for installation in ducts, direct burial in the ground and also for aerial installation with integral suspension strand. Jelly filled option is for subscriber's cables installed underground or along the edge of pavement. An armoured option is offered for direct burial installations. A figure-8 self support option is offered for aerial installation.Standards• DIN VDE 0816ConstructionConductorsSolid annealed bare copper 0.4/0.6/0.8mm, as per class 1 of DIN VDE 0295/ BS 6360/IEC 60228InsulationCellular polyethylene 2YI2 type as per VDE 0207-2Twisted PairsInsulated conductors are twisted into pairs with varying lay length to minimize crosstalkCabling ElementStar QuadsCable Core Assembly4 Cores are twisted into star quad. 5 star quads are stranded into a basic unit. 5 or 10 basic units each are stranded into one main unit. The star quads are grouped in units and stranded in layers to form the cable core.Standard make up is per VDE 0816 in the Cable Make Up DiagramCore WrappingOne or more non-hygroscopic polyester tapes are helically or longitudinally laid with an overlap. These tapes furnish thermal, mechanical as well as high dielectric protection between shielding and individual conductorsMoisture BarrierA layer of aluminium tape (0.2mm) coated with PE-copolymer on one or both sides is applied longitudinally with overlap over the cable core to provide 100% electrical shielding coverage and ensures a barrier against water vaporSheathBlack low or medium density polyethylene 2YM2 type as per VDE 0207-3, being able to withstand exposure tosunlight, temperature variations, ground chemicals and other environmental contaminantsRipcordRipcord may be provided for slitting the sheath longitudinally to facilitate its removalSpare Pairs (optional)Spare pairs may be provided for large pair cablesContinuity Wire (optional)Tinned copper drain wire may be longitudinally laid to ensure electrical continuity of the screenOptional ConstructionJelly Filled CableThe cable core interstices are filled with petroleum jelly to avoid longitudinal water penetration within the cable. The water resistant filling compound is applied to the air space between non-hygroscopic tape and shield,shield and sheath within the cable coreArmoured CableCorrugated steel tape armour is applied over an optional inner polyethylene sheath with an overlap. An outer polyethylene sheath is applied over the armour Type Code
