Pulling Tension Ratio is the idea behind PTR. In outside plant installations, you pull cables through conduit or ducts and you must keep the tension on the cable within safe, specified limits to avoid damage. The PTR measures how much pulling force you’re applying relative to the cable’s allowable or recommended pulling tension. By comparing the actual tension to the maximum safe tension, you get a sense of whether the pull is on solid ground or if you need to adjust the setup—perhaps with more lubrication, shorter pull lengths, additional pulling equipment, or a different pathway—to stay within safe limits. The other options don’t fit because they describe different concepts (pipe-related tension, torque, or an unrelated ratio), whereas PTR specifically refers to pulling tension during installation.
