6 pair copper Cat 3 outside plant 24 awg voice cable, is generally installed as aerial telephone cable between poles, in an underground conduit system, or by direct underground burial. Hardware associated with the outside plant must be either protected from the elements (for example, distribution frames are generally protected by a street side cabinet) or constructed with materials suitable for exposure to the elements.
PE22 solid insulated unfilled telephone wire:
PE22 ALPETH Outside Plant Cable is a solid insulated, single jacket air core design intended for above ground aerial installations. In this application the PE-22 cable can be attached to a support strand (messenger). ALPETH cable is not recommended for any buried or duct application, with or without air pressure.
Insulation:
Dual insulation consisting of an inner layer of foamed polyethylene
surrounded by a solid polyethylene skin, color-coded in accordance with
telephone industry standards
Twisted Pairs:
Insulated conductors are twisted into pairs with varying lay lengths to minimize crosstalk
Core Assembly:
25 pairs and less: pairs are assembled together in a single group
More than 25 pairs: pairs are arranged in groups, each group having a color coded unit binder.
Core Wrap:
Non-hygroscopic dielectric tape applied longitudinally with an overlap
Aluminum Shield:
Corrugated, co-polymer coated, 0.008" aluminum tape applied longitudinally with an overlap
The sheath interfaces are flooded with an adhesive water-blocking compound
Jacket:
Black, linear low density polyethylene Application(s):
Compliance:
Rural Development Utility Program(RDUP) 7 CFR 1755.890 (RUS PE-89)
