China Drop Wire 1X2X0.5cu+Steel Wire Telephone Cable Computer Cable Data Cable Communication Cable Connector Audio Cable

Drop Wire Cable
Application
The 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.
Construction
Conductors
Solid annealed bare copper 0.4/0.6/0.8mm, 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
Cabling Element
Star Quads
Cable Core Assembly
4 Cores are twisted into star quad.
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
Moisture Barrier
A layer of aluminium tape (0.02mm) 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 vapor
Sheath
Black low or medium density polyethylene , 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
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
