(Summary description)Price is an important indicator of a commodity. To a large extent, the level of the price shows the quality of the commodity and also determines whether the buyer and seller can reach a transaction. In the retail and wholesale markets of the cable industry, price wars are not uncommon, especially in the past few years, whoever has a low price can make a sale. The common quotation calculation formulas of cables mentioned in "Cablebao Cable Application Technology Research Institute" can provide important basis and reference for your purchase. Quick and accurate quotation to customers is the most basic skill of a salesperson. Therefore, as a cable buyer, editor Ren Yi reminds you, don’t hurry up to collect it!

Price is an important indicator of a commodity. To a large extent, the level of the price shows the quality of the commodity and also determines whether the buyer and seller can reach a transaction. In the retail and wholesale markets of the cable industry, price wars are not uncommon, especially in the past few years, whoever has a low price can make a sale. The common quotation calculation formulas of cables mentioned in "Cablebao Cable Application Technology Research Institute" can provide important basis and reference for your purchase. Quick and accurate quotation to customers is the most basic skill of a salesperson. Therefore, as a cable buyer, editor Ren Yi reminds you, don’t hurry up to collect it!
Basic principles of calculation formula:
Selling price = conductor cost + material cost + additional cost (such as freight, etc.) + profit
The cable is composed of conductor, insulation, sheath, shield, steel strip and other materials. Among them, the cost of conductor (copper, aluminum) accounts for more than 80%. Therefore, calculate the cost of the conductor, and you can get the cost of this type of cable. Approximate price, the cost of other materials is relatively stable, just add it directly. Therefore, we mainly introduce how to calculate the cost price of conductors.
Copper core power cable:
Copper cost = copper weight x number of wires x copper price
= Copper density x copper volume x number of wires x copper price
=8.9g/cm3 x square number (mm2) x 1 meter x copper price
The unit of the specifications we are used to talking about (for example, 25 square meters, 3*50+1) is mm2, and the length to be calculated is 1 meter. We are also used to talking about the price per ton for the copper price, so the unit is not uniform. We want to unify the units. At this time, the density of copper becomes 0.0089, and the price of copper is correspondingly reduced by 1000 times.
For example: Let's calculate the cost of YJV3*4 copper, the copper price is 38,000 yuan/ton. That is: 4x0.0089x3 x38=4.06 yuan. Then add other materials and profits to get the selling price of 1 meter YJV3*4.
The same is true for aluminum core power cables. For example, if the price of YJLV4*25 is calculated, the aluminum price is calculated at 12,000 yuan/ton. That is: 25x0.0027x4 x12=3.24 yuan, plus other materials and profits, and get the sales unit price of YJLV4*25.
If a represents the square number and b represents the unit price of the conductor, the calculation formula for the conductor cost is: 0.0089ab (copper); 0.0027ab (aluminum)
But in the actual cable market, many manufacturers are not quoting the price of the national standard cable, but only tell you the conductor wire diameter, then how to calculate his high or low price?
The principle is the same, just calculate the actual conductor square, and then apply it to 0.0089ab or 0.0027ab. (Square = diameter x diameter x 0.785 x number of roots).
For example: only know that the wire diameter of YJV5x6 is 2.5mm, then its actual square is 2.5x2.5x0.785=4.9mm2, and the cost of copper is 0.0089ab=0.0089x4.9x5 x38=8.3 yuan.
The above copper price is calculated at 38,000 yuan/ton, and the aluminum price is calculated at 12,000 yuan/ton. The actual price shall prevail in the actual calculation;
The density of copper is 8.9g/cm3, and the density of aluminum is 2.7g/cm3. Aluminum alloy conductors cannot be calculated by the density of aluminum;
The formula used: d=πr2, v=sh, m=ρv
In fact, cable products do not have any complicated structure, so the price calculation is very simple. I hope that I will not calculate it before, and I can grasp it flexibly after reading it; I will calculate it before, and I hope it can help you understand the formula better. If you feel that there is something wrong with the writing, please correct me. If you have anything you want to say, you can also reply directly in the official account, and I am happy to discuss with you.
