The distance is 400 meters. Is it possible to use 120 of the aluminum core cable? If not, how much cable should be used? Empty 20How big the cable 250KW piling machine, the distance is 400 meters, can use the aluminum core cable 120, if not, the cable for much, much of the air distribution.
This is the minimum limit. The air switch shall be 630 safe. With a soft starter box, if the star triangle is activated, two 240 square cables can be used to connect the six terminals of the motor and the starter box.
What's more, your distance is 400 meters, the wire reaches full load, so far distance, voltage loss is also very big. Therefore, the proposed use of two 240 square meters of aluminum core cable parallel operation.
Hello, is this pile driver 380V? It's not 3KV or 6kV, is it? If it is 380V, 250KW motor rated current is about 450 security, and the aluminum core cable 240 square in 30 degrees Celsius environment safe carrying capacity of 240, the actual use, 240 square aluminum in the current 240, fever is very serious.
