The price (based on the quoted price of 60,000 yuan/ton for the Yangtze River nonferrous metal mesh copper futures) is between 138 yuan -246 yuan. At present, the price control of wire and cable in our country is still not perfect, because when we buy wire and cable, we must shop around and choose the right product among the products of the same quality.

Cost calculation of wire and cable
If you want to buy high-quality and cheap wires and cables, you must first have a general understanding of the cost calculation of wires and cables.
The wires and cables we often use belong to cloth wires, also called household cables. The conductor structure is simple and the cost is easy to calculate. Wires consist of insulators (PVC) and conductors (copper or aluminum). Firstly, the cost calculation method of conductor (copper) is introduced:
1, calculate the weight of copper first.
Weight of copper = density of copper (0.0089)* volume of conductor (copper). The volume of copper is the same as that of the calculated cylinder. Bottom area * height (that is, the length of the conductor). To calculate the area of copper wire, the diameter of copper wire must be measured first.
The diameter of the copper wire is 1.772, so the square of the area =( 1.772 divided by 2) *3. 14=2.46.
The area is 2..46* the height is 100* the specific gravity of copper is 0..0089=2. 1894, which is the copper wire weight of this wire.
2. Copper wire weight * copper wire price (55.7 yuan/kg) = 122 yuan. This is the price of copper wire.
3. Cost calculation of PVC insulation: the total weight of wires-the weight of copper = the weight of insulation, multiplied by the price of PVC material (8 yuan/kg) = the price of insulation.
4, plus 5% of the production cost is the cost price of this line.
Note: The calculation method of aluminum core wire is the same as above. The specific gravity of aluminum wire is 0.0027.
