PAP is a commonly used term for air core, unfilled direct-burial telephone cable with a corrugated aluminum shield, designed for underground communication.
PAP refers to a type of direct-burial telephone cable built with an air core construction, meaning the interior is unfilled rather than packed with a moisture-blocking compound, and protected by a corrugated aluminum shield. The corrugated shield provides mechanical strength and electrical protection while allowing the cable to flex, and the construction is intended for direct burial in the ground.
Direct-burial communication cable must withstand the conditions of an underground environment, including moisture, soil pressure, and mechanical stress. The aluminum shield in a PAP cable contributes protection and shielding, while the air core construction reflects a particular design choice for the cable's intended service.
In commercial and industrial communication, direct-burial cables like PAP support outdoor and underground telephone and signal runs. Recognizing the construction helps in understanding how such cable is built to endure the demands of buried service.
Because the underground environment subjects cable to moisture, soil pressure, and mechanical stress, direct-burial constructions are built to endure these conditions, and the corrugated aluminum shield contributes both protection and shielding while allowing the cable the flexibility it needs.
Recognizing how shielding and construction suit underground service helps illustrate the considerations behind dependable direct-burial communication cable in commercial and industrial outdoor applications.
At Windy City Wire, an understanding of communication cable constructions, including direct-burial types, reflects a focus on matching cable to its environment.
