Ordering Information

Solid PE Insulated & PE Sheathed Jelly Filled Cables to CW 1326& CW 1326/1179

Application

The cables are designed for use as subscriber distribution cables and as connection between central offices in local access networks. The cables are jelly filled and suitable for installation in ducts. The cables are also available for direct burial in the ground and aerial installation with integral suspension strand. An armoured option is offered for direct burial installations. A figure-8 self support option is offered for aerial installation.

Standards

CW 1326& CW 1326/1179CW 1326& CW 1326/1179

CW 1326 (For unscreened cable)

CW 1179 (For screened cable)

CW 1252 (For self-supporting cable)

Construction

Conductors: Solid annealed bare copper, 0.5mm as per class 1 of BS 6360/IEC 60228

Insulation: Solid polyethylene as per BS EN 50290-2-23/BS 6234/IEC 60708

TwistedPairs: Insulated conductors are twisted into pairs with varying lay length to minimize crosstalk

CablingElement: Twisted Pairs

CableCore Assembly: Cables are composed of 10-pair units

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 (optional): A layer of aluminium tape (0.15mm) coated with PE-copolymer on one or both sides is applied longitudinally with overlap over the cable core to provide shielding coverage and ensure a barrier against water vapor

Filling: 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

Sheath: Black low density polyethylene as per BS 6234/IEC 60708, 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

SparePairs (optional): Spare pairs may be incorporated for 200 and larger pair cables

Continuity Wire (optional): Tinned copper drain wire may be longitudinally laid to ensure electrical continuity of the screen
