How many wiring modes are there for the complete set of switchgear?

A complete set of switchgear, which includes the combination of spare parts involved in the switchgear, is also an electrical equipment; It enters the main control switch in the cabinet from the external line, and then enters the sub control switch. Each branch is set according to its needs. So I don't know how much you know about the connection mode of the complete set of switchgear. If you don't know, let's take a look!

The conventional incoming and outgoing lines on the switch cabinet basically have two connection modes:

(1) Incoming and outgoing cables are connected in the cable room;

(2) The incoming and outgoing lines are led out by the wall bushing on the top of the cabinet and connected with the bus bridge, or the bus bridge is connected with the overhead line through the wall bushing. There are also a few users. Cables are introduced from the top of the cabinet through the cable rack and connected in the cabinet, or connected on the top of the cabinet, and another safety net frame is set.

Although the user provided a system diagram and standard scheme when ordering, the way of incoming and outgoing lines cannot be completely expressed clearly. The user should explain it in the technical agreement according to the actual installation requirements on site, so as to avoid difficulties in on-site installation. You can also ask professionals for help!
