Telephone Cable

With an ample supply of Telephone Cable Wiring in stock from the manufacturers Teldor, Superior Essex, Belden, and General Cable, we offer a variety of cables for use in remote telephony equipment power as well as many non-telephone applications. Some of these uses include PCM (Pulse Code Modulation) and FDM (Frequency Division Modulation) repeaters, telegraph systems, and other categories of control circuitry.

These telephone cable types can be expected to have suitable levels of performance in aerial installations, in ducts or conduits, and in direct burial installations, in ducts or conduits, and in direct burial installations. The highest level of safety and current handling capabilities will be found in duct or direct burial applications.

While browsing the selection of Telephone Cable products on our site, it may be helpful to understand some of the differences that exist among their constructions and the applications they are used for. The first major category of these is Outside Plant Telephone Cable, also designated as PE39, PE54, or PE89, which is mainly utilized in exchange areas or trunk service. It is able to installed in ducts or by direct burial. Cable types PE39, PE54, and PE89 have conductors made of solid, soft drawn bare copper and insulation constructed of high-density polyethylene or polypropylene. While their cores contain an extended thermoplastic rubber (ETPR) compound, the inner and outer jackets of PE39, PE54, and PE89 consist of black polyethylene and their shielding, if applicable, is generally made of corrugated aluminum.

A second popular variety of Telephone Cable is PE38, which is specially intended for aerial installation. With a solid, annealed, bare copper conductor construction, these are well made for applications using voice and carrier frequency on either all pairs or selected pairs. Like other product categories in this area, they have the feature of color-coding on their polyolefin (PO) insulation, in line with telephone industry standards.

Finally, PE89 rated cable of this type is quite similar to PE39, PE54, and PE89 because of its being used in direct burial, duct, distribution circuit, and service entrance applications. A crucial difference, however, is that these are also equipped to withstand threats from environmental factors and rodents—something which explains the descriptions on our site calling them “Gopher Resistant.” There are several features that make these durable in such situations. One feature is their wire core, which is filled entirely with an ETPR compound rated at 80 degrees Celsius, as well as an inner jacket constructed of low-density and linear PE material. The shielding consists of a corrugated, flooded, and gopher-resistant armor. Finally, a black PE outer jacket is robust to protect the cable against sun exposure and other stresses due to atmospheric or environmental conditions.

Based on the specific cable types within these categories that you require for your application, you will find a number of different ways in which to narrow down your selections based on important criteria like gauge size and pair numbers. AWG sizes for the Telephone Cable we sell run in 19, 22, and 24. The number of choices related to pairs is even greater, with telephone cable in configurations ranging from 2 through 200 pairs.
