The price formula of the control cable is as follows: weight of copper X copper price = (wire diameter ÷2) ^2X3.14X number of wires X 8.9X copper price at that time + 10% processing fee.
Cost-price calculation of control cables
Square X1.83 = weight of copper X copper price at that time + price of armor (weight X 0.4 yuan / catty) = cost price + 10% processing fee
The price of the cable = manufacturing material cost + fixed expenses + taxes + operating expenses + profits
Manufacturing material cost = material cost * (1 + material consumption) (material cost is the theoretically calculated value)
Fixed expenses vary depending on the company's situation, but generally include production wages, management wages, utility costs, repair costs, depreciation costs, rent costs, and transportation costs.
The common faults of control cable lines include mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, cable overheating fault, etc. When the above fault occurs in the line, the power supply of the faulty cable should be cut off, the fault point should be found, the fault should be checked and analyzed, and then repaired and tested.
