YJV-4 * 240 + 1 * 120 and YJV-4 * 50 + 1 * . the two cables to wear a DN150 of the steel pipe, I have the thickness of the cable, my mind did not concept! More

Wires we generally use welded pipe, weak with KBG tube, part of the Party has repeatedly asked to use PVC pipe.

Need to do the equipotential bonding of the pipe (ground wire).

A: need to do the equipotential bonding of the pipe (ground wire). Galvanized steel pipe (that is, electrical design drawings often appear in the SC tube) is connected with the use of pipe hoop wire connection, and pipe sets of wire after the junction without galvanized layer, can not constitute an electrical path, so to use cross-copper Cord, and the crossover is also directly connected with the card crimp. KBG tube is buckle-type wire tube, the use of thin-walled sheet processing and double-sided cold galvanized, pipe and pipe fittings do not need to connect the ground. The connection is the same with the pipe galvanized pipe joints directly crimp, the connection of the galvanized layer is not damaged, so do not have another cross, even if the cross is also the same with the card crimping, the way, the role of direct crimping it's the same. JDG wire tube full name tight galvanized thin-walled wire tube, pipe connection with a special pipe joints with special tools to break the screw to achieve the effect of tight connection, the electrical path is very good do not do jumper connection.
