#### 廢舊電纜 銅芯比重

 核心提示：電纜的價格=制造材料成本+固定費用+稅收+業務費+利潤 制造材料成本=材料成本*(1+材料消耗)(材料成本即為理論計算出來的值)
YJV成本價格計算公式

YJV銅芯電力電纜系列成本價格公式如下:

=平方數X絲的根數X0.89X當時銅價+10%的加工費。

YJV Cost Price Formula

The cost price formula of YJV copper core power cable series is as follows:

Copper weight X copper price calculation:

Filament diameter 2 = 1.25X1.25X3.14

= The root number of square X filament X0.89X at that time copper price + 10% processing fee.

Cost-Price Formula for Rubber Sheathed Cable

Square X1.83 = weight of copper X The price of copper at that time + price of rubber (weight X0.4 yuan/kg) = cost price + processing fee of 10%.

Cable price = cost of manufacturing materials + fixed cost + tax + business cost + profit

Manufacturing Material Cost = Material Cost * (1 + Material Consumption) (Material Cost is the value calculated theoretically)

Fixed costs vary from company to company, generally including production wages, management wages, utilities, repairs, depreciation, rent and transportation costs.

Formula for Calculating Carrier Flow

"二點五下乘以九，往上減一順號走"說的是2.5mm'及以下的各種截面鋁芯絕緣線，其載流量約為截面數的9倍。如2.5mm'導線，載流量為2.5×9=22.5(A)。從4mm'及以上導線的載流量和截面數的倍數關系是順著線號往上排，倍數逐次減l，即4×8、6×7、10×6、16×5、25×4。

"三十五乘三點五，雙雙成組減點五"，說的是35mm"的導線載流量為截面數的3.5倍，即35×3.5=122.5(A)。從50mm'及以上的導線，其載流量與截面數之間的倍數關系變為兩個兩個線號成一組，倍數依次減0.5。即50、70mm'導線的載流量為截面數的3倍;95、120mm"導線載流量是其截面積數的2.5倍，依次類推。

"條件有變加折算，高溫九折銅升級"。上述口訣是鋁芯絕緣線、明敷在環境溫度25℃的條件下而定的。若鋁芯絕緣線明敷在環境溫度長期高于25℃的地區，導線載流量可按上述口訣計算方法算出，然后再打九折即可;當使用的不是鋁線而是銅芯絕緣線，它的載流量要比同規格鋁線略大一些，可按上述口訣方法算出比鋁線加大一個線號的載流量。如16mm'銅線的載流量，可按25mm2鋁線計算。

" 穿管根數二三四，八七六折滿載流"穿管敷設兩根、三根、四根電線的情況下，其載流量分別是電工口決計算載流量(單根敷設)的80%、70%、60%。
Estimation formula

Divide it by nine at 2.5 and go up by one.

Thirty-five times three-five, double double group minus five.

Conditions include variable plus conversion and high temperature copper upgrade.

The number of penetrating roots is 234 and 876 are discounted to full current.

Note: The formula in this section does not directly indicate the current carrying capacity (safe current) of various insulating wires (rubber and plastic insulating wires), but is expressed by "multiplying the cross section by a certain number", which is obtained by mental calculation. It can be seen from Table 53 that the multiple decreases with the increase of cross section.

Divide it by nine at 2.5 and go up by one.

"Two-five times nine, one step up and one step down" refers to all kinds of cross-sectional aluminium core insulating wires with 2.5mm'or less, and their carrying capacity is about nine times of the cross-sectional number. For a 2.5mm'conductor, the current carrying capacity is 2.5 x 9 = 22.5 (A). The multiplier relationship between the current carrying capacity and the number of cross sections of conductors above 4mm'is arranged upward along the line number, and the multiplier is reduced by L successively, i.e. 4*8, 6*7, 10*6, 16*5 and 25*4.

Thirty-five times three-five, double double group minus five.

"Thirty-five times three-point-five, double double group minus-five" means that the conductor carrying capacity of 35mm "is 3.5 times of the cross-section number, that is, 35 x 3.5 = 122.5 (A). From 50 mm'or more conductors, the multiplier relationship between the carrying capacity and the cross-section number becomes a group of two line numbers, and the multiplier decreases by 0.5 in turn. That is to say, the carrying capacity of 50 and 70 mm'conductors is three times of the cross-section number; the carrying capacity of 95 and 120 mm conductors is 2.5 times of the cross-section number, and so on.

Conditions include variable plus conversion and high temperature copper upgrade.

"Conditions are converted to change plus, high temperature copper upgrade with 10% discount". The above formula is based on the fact that the insulating wire with aluminium core is laid on the surface at the ambient temperature of 25 C. If the aluminium core insulating wire is laid in the area where the ambient temperature is longer than 25 C, the current carrying capacity of the conductor can be calculated according to the above formula calculation method, and then discounted by 10%. When the copper core insulating wire is used instead of the aluminium wire, its current carrying capacity is slightly larger than that of the aluminium wire of the same specification, the current carrying capacity of the copper core insulating wire can be calculated by the above formula method, which is one line number larger than that of the aluminium wire. If the carrying capacity of 16 mm'copper wire is calculated according to 25 mm 2 aluminum wire.

The number of penetrating roots is 234 and 876 are discounted to full current.

When two, three and four wires are laid through the pipe, the carrying capacity is 80%, 70% and 60% of the calculated carrying capacity (single laying) by the electrician, respectively.
