Description

Technical Parameters

Brief Introduction

The size of the cable used for 400 kw motor is uncertain and depends on the specific circuit conditions. Generally speaking, copper cables for 400 kilowatts are 180 square millimeters and aluminum cables are 240 square millimeters. Calculation method: Based on the three-phase AC power, P=√ 3UIcosa is calculated, and cosa is the power factor, with a value of 0.85. I=400000 ÷ (1.732 × three hundred and eighty × 0.85)=715A. According to the cable ammeter, the copper cable is 180 square millimeters and the aluminum cable is 240 square millimeters.
