2 Core Flat Communication External Data Telephone Line Wire

Product DescriptionFlat/round 2 core 1pair telephone cableApplicationThe cables are designed for using 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. ConstructionConductors Solid annealed bare copper 0.4/0.6/0.8/1.0mm, as per class 1 of DIN VDE 0295/ BS 6360/IEC 60228 Insulation Cellular polyethylene 2YI2 type as per VDE 0207-2 Twisted Pairs Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk Core Wrapping One 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 conductors Sheath Black low or medium density polyethylene 2YM2 type as per VDE 0207-3, being able to withstand exposure to sunlight, temperature variations, ground chemicals and other environmental contaminants Ripcord Ripcord may be provided for slitting the sheath longitudinally to facilitate its removal Spare Pairs (optional) Spare pairs may be provided for large pair cables Continuity Wire (optional) Tinned copper drain wire may be longitudinally laid to ensure electrical continuity of the screen Optional Construction Jelly Filled Cable The 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 core Armoured Cable Corrugated steel tape armour is applied over an optional inner polyethylene sheath with an overlap. An outer polyethylene sheath is applied over the armour Product ParametersType CodeA-Outdoor Cable02YCellular Polyethylene (FOAM PE) insulationF Continuous core filling(L)2Y Laminated sheath(copolymer-coated aluminium tape laminated to PE outer sheath)SR Corrugated steel tapebArmouringT Messenger of galvanized steel wiresStIIIStar quad in local cablesBd Unit-type strandingElectrical Properties Nominal Conductor Diametermm0.40.60.8Conductor Gauge SizeAWG26-20Conductor Sizemm20.1260.2830.5Maximum Average Conductor Resistance @20°C/km1436334.6Minimum Insulation Resistance @500V DCM.km500050005000Maximum Mutual Capacitance @800Hz 95% of all valuesnF/km404040                                                              100% of all valuesnF/km424242Capacitance Unbalance @800Hz pair-to-pair             K1          100% of values maxpF/500m980800800                        98% of values  maxpF/500m420400400         K9-12    100% of values maxpF/500m800300300                        90% of values  maxpF/500m200100100Maximum Conductor Loop Resistance @20°C/km30013073.2Impedance @0.8KHz 994665500Maximum Average Attenuation @0.8KHzdB/km1.450.910.68Dielectric Strength 50Hz             Conductor to Conductor (2mins)V AC500500500         Conductor to Screen (2mins)V AC200020002000Maximum Operating Voltage Peak ValueV150225225Nominal Insulation Thickness (Air Core)mm0.200.250.3                                                  (Jelly Filled)mm0.260.360.44Nominal Insulated Conductor Diameter (Air Core)mm0.81.11.4                                                                (Jelly Filled)mm0.921.321.68  Detailed PhotosCompany ProfileABOUT USZhejiang Hanli Cable Co., Ltd. is a professional manufacturer of tv cables and cable television network equipment.
