Gurus! Seek acceptance criteria for control cables

Some 1.5 square millimeter single-core control cables have arrived at the site; using a multimeter, the resistance of each cable was found to be 27 ohms, and their length is 2200 meters. Are such control cables considered acceptable?

Cable acceptance should not be based solely on the conductance resistance; tests such as voltage withstanding tests and insulation tests are equally important. You didn’t specify the exact model of the cable, so I can only provide a standard; you can use the instructions included there for inspection.

Did Xi’an Metro fail because of the control cables?
