The price formula for control cables is as follows: Copper weight x Copper price = (Wire diameter ÷ 2)^2 x 3.14 x Number of wires x 8.9 x Current copper price + 10% processing fee.
Control Cable Cost Calculation: Square mm x 1.83 = Copper weight x Current copper price + Armor price (weight x 0.4 yuan/catties) = Cost price + 10% processing fee. Cable price = Manufacturing material cost + Fixed costs + Taxes + Business expenses + Profit. Manufacturing material cost = Material cost * (1 + Material consumption) (Material cost is the theoretically calculated value). Fixed costs vary depending on the company and generally include production wages, management wages, water and electricity fees, repair fees, depreciation fees, rent, and transportation costs. Common faults in control cable lines include mechanical damage, insulation damage, insulation dampness, insulation aging and deterioration, overvoltage, and cable overheating. When the above-mentioned faults occur in the line, the power supply to the faulty cable should be cut off, the fault point should be located, the fault should be inspected and analyzed, and then repairs and tests should be carried out. Any cables that need to be cut off should be cut off. Power supply can only be restored after the fault is eliminated.
