Ganzhou Control Cable
The core of the control cable is a copper core, with a nominal cross section of 2.5mm2 and below, 2 to 61 cores; 4 to 6mm2, 2 to 14 cores; 10mm2, 2 to 10 cores. Control cable working temperature: rubber insulation is 65 ° C, PVC insulation is 70 ° C and 105 ° C. The control cables used in computer systems generally use polyvinyl chloride, polyethylene, cross-linked polyethylene, and fluoroplastic insulation products.
Control cable maintenance:
The control cable price formula is as follows: copper weight X copper price = (wire diameter ÷ 2) ^ 2X3.14X number of wires X8.9X copper price + 10% processing fee at that time.
Cost price calculation of control cables
Square X1.83 = weight of copper X copper price at that time + armor price (weight X 0.4 yuan / catty) = cost price + 10% processing fee
The price of the cable = cost of manufacturing materials + fixed costs + taxes + business fees + profit
Manufacturing material cost = material cost * (1 + material consumption) (material cost is the value calculated theoretically)
The fixed fee varies according to the situation of each company, and generally includes production wages, management wages, utilities, repair fees, depreciation fees, rents, and transportation costs
Common faults of control cable lines include mechanical damage, insulation damage, insulation moisture, insulation deterioration, overvoltage, and cable overheating failures. When the above-mentioned fault occurs in the line, the power 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. The cut-off should be removed before the power can be restored.
