Edit this paragraph Mine communication cable picture instance of mining the communication cables ore with communication cables, Model: MHYV Specifications: 1 × 4 edit this paragraph Mine communication cable price calculation formula mine communication cable prices formula Mine communication cable series price The formula is as follows: the weight of copper X Copper prices: root the number X0.89X then copper of the wire by ÷ 2 = 1.25X1.25X3.14 = the square of the number of X-wire +10% processing fee. Mine communication cable cost prices square X1.83 = the copper weight X when the price of copper + armored Price (weight X0.4 / kg) = cost price +10% processing fee cable price = manufacturing cost of materials + fixed cost + tax + operating expenses + profit manufacturing material cost = material cost * (1 + material consumption) (cost of materials shall be theoretically calculated values) fixed costs according to each company's situation is different, and generally include production wages management wages, utilities, repairs, depreciation charges, rental fees, transportation costs editing the wire and cable industry profile wire and cable industry is the second largest industry, second only to the automotive industry in China to meet the rate of product variety and domestic market share are more than 90%. Worldwide, the total output value of China's wire and cable has surpassed the United States to become the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises are increasing the technical level of industry as a whole has been a substantial increase in China's sustained and rapid economic growth and huge market space for cable products, a strong allure of the Chinese market, making the world all eyes are focused on the Chinese market in just a few decades of reform and opening up, China's cable manufacturing industry the formation of a huge production capacity to make the world sit up and take notice. With the continuous expansion of the scale of China's power industry, the data communications industry, urban rail transit industry, the automotive industry, as well as shipbuilding and other industries, the demand for wire and cable will be rapid growth in the wire and cable industry, there is a huge potential for development.
