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.
PE89 Foam skin insulated filled telephone cable:
PE89 Filled ALPETH Cable with foam skin insulation is a single
jacket, filled design. Intended for direct burial underground
applications. An ETPR compound completely coats
each insulated conductor and fills the air space between conductors. The
shielding and jacket combined with the filling and flooding compounds
throughout the PE-89 cable provide exceptional durability and resistance
to moisture.
PE89 gel filled telephone cable is suitable for outdoor applications
without the use of conduit. The cable is filled with water resistant
jell and UV resistant. The conductors are 24awg and follow the industry
standard color code for twisted pair cables. Direct burial telephone
cable must not be run for more than 50ft inside buildings (per the
National Electrical Code).
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)
