First of all, insulation material:
YJ-XLPE Insulation
V-PVC Insulation

Sheath Material:
V-PVC
From this we can see that the biggest difference between the two is in the insulation material, who is better? The maximum allowable working temperature of VV cable is 70 C. The maximum allowable working temperature of YJV cross-linked cable is 90 C. The thermal performance of VV cable is better and the allowable carrying capacity is larger. Therefore, YJV cable is superior to VV cable in performance and higher in price.

How to calculate the current of three-phase motor? The current of three-phase motor is calculated according to the following formula:

I = P (3 U cos_) i. e. current = power (watt)/ (3 * 380 (volt)* 0.8)

The simplified formula is: I = rated power (KW)* 1.8

Note:

U is the line voltage, usually 380V.

Cos_is the load power factor, usually 0.75, and now the new motor has reached 0.8 or 0.9.

3=1.732
