Cable Distribution Cabinet
The cable distribution cabinet adopts component module assembly and frame assembly structure, and the bus and feed out are insulated enclosed.
Five structural types can be adopted:
1. The incoming line adopts insulated enclosed disconnector, and the outgoing line adopts MCCB;
2. The incoming line adopts insulated enclosed disconnector, and the outgoing line adopts knife fuse switch;
3. The incoming line adopts strip disconnector and the outgoing line adopts strip switch (with fuse protection);
4. The incoming line does not have a switch, and the outgoing line adopts a knife melting switch;
5. The incoming and outgoing lines are not equipped with switches.
