Electrical system for Irreversible Aluminium Cold Rolling Mill

Description

Power supply

AC 10KV,50HZ,3 phase

AC380V,50HZ,3 phase

Note: The power supply voltage fluctuation is required to be no more than ±10%, and the frequency is 50HZ±1HZ24-2

AC Motor Control Center (MCC), including:

—Incoming cabinet from user power transformer

—AC motor (group) feeder

—Auxiliary system power

The AC motor control center adopts centralized control mode, which has

compact structure and reliable performance. The AC motor control center is used to complete the power distribution and control functions of the auxiliary process equipment of the rolling mill.
