Outside Telephone

Air Core Cable, Aerial and Duct

During the early 1950’s, the American development of thermoplastic insulated and jacketed exchange area telephone cables produced a revolution in world tele-phony. Prior to this development, telephone cables had historically been paper insulated, lead-jacketed designs. These cables were heavy, non or partially color-coded, difficult to splice, expensive (especially in the smaller pair counts), susceptible to moisture, costly to maintain and had electrical characteristics inferior to today’s standards.

Thermoplastic technology produced a series of cable designs which were lightweight, fully color-coded, readily spliceable, relatively low cost, maintainable at minimum cost and offered improved electrical characteristics to meet increasingly sophisticated requirements.

During the post-World War II period, the Rural Electrification Administration (REA) in the Department of Agriculture of the U.S. Federal Government began a low-interest loan program for the 3,000-plus telephone companies in the nation which were independent of the Bell and General Systems. Material, construction and engineering standards were developed in cooperation with American cable manu-facturers. Cable Core Construction and Construction Practices were published.

Since then, continuously revised and updated cable specifications assure the availability of high-quality cables with uniform performance characteristics. Of special significance are the outer jacket characteristics of high resistance to weather and environmental expo-

sure. Field-proven by American telephony, the outside installation advantages of these cables are available for other industrial telemetering and communication applications as well.

Today, REA has been reidentified as RUS/RDUP to cover a wider range of rurally placed utility services. Our RUS/RDUP designations name a certifiable family of product within telecommunications.

Filled Cable, Direct BurialThe development of filled cable was initially prompted

by transmission variables experienced in air core direct earth burial cables and wires. The filling is a water-blocking compound applied in liquid state to twisted pair cable core assemblies and to both sides of the overall metal shielding tape(s). The entire cable assembly under the outer cable jacket is 100% filled, eliminating possible moisture migration or humidity changes due to ingress or outer jacket damage. Filled cables offer improved electrical transmission character-istic stability and in-service experience has proven that they are practically devoid of maintenance costs.

RUS/RDUP Spec. PE-39 was the original speci-fication covering filled cable. These cables use solid thermoplastic conductor insulations, and are catalogued as Types BJFA, BJFC, BJFG and BJFAS. In 1982, RUS/RDUP Spec. PE-89 was written to cover filled cables having expanded (foamed) thermoplastic conduc-tor insulations. These cables are catalogued as Types BJFAF and BFASF.

Outside Telephone WiresOutside telephone wires may be grouped into three

basic categories:Direct Earth Burial Distribution WiresExtend the cable plant in rural or sparsely-populated areas. They also are used as a direct burial drop wire, connecting a subscriber to the nearest cable terminal/pedestal.Aerial Drop WiresProvide self-supporting connection from a cable or line wire system to the individual subscriber.Aerial Distribution WiresProvide a self-supporting extension of a cable plant in rural or sparsely-populated areas.

Air Core Cable

ALP Air Core, Aerial and Duct RUS/RDUP Spec PE-22For primarily aerial installation by attachment to a support strand.The cable must be pressurized if it is placed in a duct. If used in an under-ground duct, pressurization is recommended.

RUS/RDUP Designation: CA

Electrical Characteristics: See Table A on page 21 in this section.

Note: T-Screen® Type ALP cables may be available with a core separated design for use with PCM-type carrier equipment.

Conductors Solid, annealed bare copper in 19, 22, 24 and 26 AWGInsulation Solid, color-coded polyolefin

Twisted Pairs Individual insulated conductors are twisted into pairs with varying lay lengths

Core AssemblyCables of 25 pairs or less are assembled into a cylindrical core. Cables larger than 25 pairs are assembled into units, which are then used to assemble the core. Units are individually identifiable by color coded unit binders.

Core Wrap Non-hygroscopic, dielectric tapeShielding Corrugated, copolymer coated, .008" aluminum tape applied longitudinally with an overlap

Outer Jacket Black, linear low-density PE designed to withstand exposure to direct sunlight, atmospheric temperature changes and stresses expected in standard installations

Footage Marking Printed sequentially every 2' along the outer jacket

Conductors Solid annealed copper in 19, 22 and 24 AWG

Insulation Each conductor is insulated with color-coded solid polyolefin. The insulation of the tip conductor is marked with a stripe of the mating ring insulation color.

Core AssemblyIndividual conductor dimensions are tightly controlled to limit resistance unbalance of twisted pairs. Pair twist lays are varied to minimize crosstalk and meet capacitance unbalance limits.

Filling Compound The wire core is completely filled with an 80°C ETPR compound, filling the air spaces between insulated conductors

Inner Jacket PE

Shielding A smooth or corrugated copolymer-coated, .008" aluminum tape is applied longitudinally over the inner jacket and is bonded to the outer jacket. The space under the tape is flooded.
