What does YJV22 power cable mean? Below is an introduction to the meaning of YJV22 cable models and YJV22 price calculation.
YJV22 cable stands for: Copper core conductor, cross-linked polyethylene insulation, PVC inner sheath, double steel tape armor, PVC outer sheath power cable.
1. Meaning of YJV22 cable models
Y: Polyethylene, J: Cross-linked, V: PVC sheath
22: Steel tape armor, PVC sheath
YJV22 cable is a cross-linked steel tape armored cable with a copper core conductor.
Armored cables generally have a two-digit symbol. The second-to-last digit indicates armoring. Unarmored cable is unarmored.
For example, YJV23: YJ indicates cross-linked polyethylene insulation, V indicates PVC inner sheath, 2 indicates double steel tape armor, and 3 indicates polyethylene outer sheath.
2. YJV22 cable outer diameter
YJV22 cable is a cross-linked steel tape armored cable. Each cable has different specifications and voltage levels, so its outer diameter varies. Even if cables of the same voltage level have the same main cable area, different numbers of cores and different neutral conductor sizes will result in different outer diameters. Therefore, it's important to provide the cable's voltage level, number of cores, main core area, neutral conductor area, and ground conductor area to determine the specific outer diameter.
3. Current Carrying Capacity of YJV22 Cables
YJV22 cables are cross-linked steel-tape armored cables with copper conductors. The safe current carrying capacity of copper conductors is generally determined based on the maximum allowable core temperature, cooling conditions, and installation conditions. Therefore, it's necessary to consider these cable conditions to determine the current carrying capacity of various specifications and models.
4. Price of YJV22 Power Cables
Calculation: Copper weight x copper price: Wire diameter ÷ 2 = 1.25 x 1.25 x 3.14 = Square footage x Number of wires x 0.89 x Current copper price + 10% processing fee. The cost of control cable is calculated as follows: square meter x 1.83 = copper weight x current copper price + armor price (weight x 0.4 yuan/jin) = cost price + 10% processing fee.
Cable price = manufacturing material cost + fixed costs + taxes + operating fees + profit.
Manufacturing material cost = material cost * (1 + material consumption) (material cost is the theoretically calculated value). The price of a 22-core cable is 30 yuan/meter. (Prices are for reference only; actual purchase prices will prevail.)
