Usage characteristics: The long-term allowable working temperature of the control cable conductor for coal mines is 70 ℃, and the cable laying temperature should not be lower than 0 ℃. The allowable bending radius for control cables used in coal mines: For cables with armor or copper tape shielding structures, it should not be less than 12 times the outer diameter of the cable. For flexible cables with a shielding layer structure, it should not be less than 6 times the outer diameter of the cable. For unarmored cables, the diameter should not be less than 6 times the outer diameter of the cable.

The product certificate should indicate the registered trademark, product name, implementation standard, product model, voltage, product specifications, cross-sectional area, product length, manufacturer, inspector, production date, manufacturer name, and be stamped with the inspector's seal. On the "certificate of conformity" of counterfeit and inferior products, the model and specifications can be arbitrarily filled in, but upon careful inspection, it is often found that there are no inspector codes, no production dates, and no production factory addresses. The inspection report for counterfeit and inferior products is often a photocopy, and the product inspection batches are also different. The specifications and models of the report and the actual product often do not match.
