Busduct and busduct system having the same

A bus duct comprising:

• an enclosure made of a metallic material;
• a plurality of pairs of busbars disposed in pairs in parallel with one another in a longitudinal direction of the enclosure and spaced apart from one another;
• a plurality of insulation members configured to mount the plurality of pairs of busbars in an insulated state in the enclosure;
• and
• a plurality of pairs of cover members mounted on a lower portion of the enclosure and configured to prevent exposure of the plurality of pairs of busbars,
• wherein the plurality of pairs of cover members are mounted on the enclosure to block connection ports of the bus duct into which connection conductors of a branch box are inserted, and the plurality of pairs of cover members are deformed inward to expose connection ports when the connection conductors of the branch box enter the connection ports,
• wherein a cover member of the plurality of pairs of cover members comprises a mounting portion mounted on the enclosure, a connection portion extending from the mounting portion toward a lower side of a connection port of the connection ports, and a plurality of blocking portions branching off from the connection portion in a direction toward the connection port, and
• wherein the plurality of blocking portions of the cover member of the plurality of pairs of cover members comprises an outer blocking portion extending from the connection portion, and an inner blocking portion extending from the connection portion toward an inside of the bus duct further than the outer blocking portion.
