Solid PE Insulated AP Sheathed ( ALPETH ) Air Core Telephone Cables to GR - 421

Solid PE Insulated  AP Sheathed (ALPETH) Air Core Telephone cables to GR-421

Application

The cables are designed for use as subscriber distribution cables and 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. An armoured option is offered for direct burial installations. A figure-8 self support option is offered for aerial installation.

Standards

Telcordia (Bellcore) GR-421

Construction

Conductors: Solid annealed bare copper, 0.4/0.5/0.63/0.9mm, as per ASTM B-3/class 1 of IEC 60228

Insulation: Solid medium or high density polyethylene as per ASTM D 1248/IEC 60708

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

Cabling Element:  Twisted Pairs

Cable  Core
Assembly:

Cables with up to 400 pairs are composed of 25-pair units or 12/13-pair units; cables with over 400 pairs are composed of 50 or 100-pair units. Any extra pairs form a separate unit. Units are identified by colour coded binders. Construction is per GR-421 given in Cable Make Up Diagram.

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 bare aluminium tape (0.2mm/8mil) is applied longitudinally with overlap over the cable core to provide 100% electrical shielding coverage and ensures a barrier against water vapor. In cables with more than 200 pairs, the aluminum tape may be corrugated for improved cable flexibility

Sheath:

Black low density polyethylene as per ASTM D 1248/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

Spare  Pairs
(optional):
Spare pairs may be incorporated for large pair cables
Continuity  Wire
(optional):
One tinned copper drain wire may be longitudinally laid to ensure electrical continuity of the screen
Optional Construction
Armoured Cable:

0.15mm thick corrugated steel tape armour is applied with an overlap over an optional inner polye- thylene sheath. An outer polyethylene sheath is applied over the armour

Self-Support
Cables

A 7-strand galvanized steel strand is used as support wire. Black polyethylene sheath covers both core and support wire in a figure-8 construction
