Solid PE Insulated & LAP Sheathed (ALPETH) Air Core Cables to ICEA S-85-625

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

ANSI/ICEA S-85-625

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 of 25 pairs or less are assembled into cylindrical core. Cables larger than 25 pairs are assembled into units, which are then used to form the core. Units are identified by colour coded binders.
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 (0.2mm) coated with PE-copolymer is applied longitudinally with overlap over the cable core to provide 100% electrical shielding coverage and ensure a barrier against water vapor.
Sheath : Black low or medium 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 provided 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 polyethylene sheath. An outer polyethylene sheath is applied over the armour.
Self-Support Cable : 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.
Shield Options : There are 8 different shield options which can be offered in this standard :
1) 8 mil bare aluminium tape
2) 8 mil coated aluminium tape
3) 5 mil copper tape
4) 5 mil copper clad alloy steel tape
5) 5 mil copper clad stainless steel tape
6) 6 mil & 7 mil 194 copper alloy tape
7) 6 mil bare steel tape
8) 6 mil coated steel tape
