Maintenance And Upkeep Of Control Cables

The formula for controlling cable prices is as follows: weight of copper X copper price=(wire diameter ÷ 2) ^ 2X3.14X number of wires X8.9X current copper price+10% processing fee.
Cost price calculation of control cables
Square X1.83=weight of copper X current copper price+armor price (weight X 0.4 yuan/jin)=cost price+10% processing fee
The price of cables=manufacturing material cost+fixed expenses+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 situation of each company, generally including production wages, management wages, utilities, repair costs, depreciation costs, rent, and transportation costs
Common faults in control cable circuits include mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, and cable overheating faults. When the above-mentioned faults occur in the circuit, the power supply of the faulty cable should be cut off, the fault point should be found, the fault should be inspected and analyzed, and then repaired and tested. The cut should be removed, and the power supply can only be restored after the fault is eliminated.
