Control cable factory direct sales
Control cable development prospect: The wire and cable industry is China's second largest industry after the automotive industry, with product variety satisfaction rates and domestic market share exceeding 90%. In the world, China's total output value of wire and cable has surpassed the United States, becoming the world's largest wire and cable producer. With the rapid development of China's wire and cable industry, the number of new enterprises has continued to rise, and the overall technical level of the industry has been greatly improved.
The sustained and rapid growth of the Chinese economy has provided huge market space for cable products. The strong temptation of the Chinese market has made the world focus on the Chinese market. In the short decades of reform and opening up, China ’s cable manufacturing industry The huge production capacity formed has made the world look amazing. With the continuous expansion of China's electric power industry, data communication industry, urban rail transportation industry, automobile industry and shipbuilding industries, the demand for wire and cable will also grow rapidly, and the wire and cable industry has huge development potential in the future.
In November 2008, in response to the world financial crisis, the government decided to invest 4 trillion yuan to stimulate domestic demand, of which about 40% was used for urban and rural power grid construction and transformation. The wire and cable industry in the country has a good market opportunity again. Wire and cable companies around the world seize the opportunity to welcome a new round of urban and rural power grid construction and transformation.
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.
