12 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).
