Description

Technical Field

[0001] The utility model relates to the technical field of trough type bridges, in particular to a trough type shaft bridge. Background Art

[0002] In high-rise buildings, the vertical transmission of electric energy and electrical signals is greater than the horizontal transmission. Large-section wires and a large number of cables are laid in the vertical direction. Therefore, in order to solve the channel and layout of longitudinal cables, plug-in busbars, and cable trays in the building, a certain cross-section of the shaft is often reserved from the bottom to the top in high-rise buildings, which is the electrical shaft.

Common wiring methods in shafts include metal conduits, metal wire ducts, various cables or cable trays, and closed busbars. When installing cables in existing trough-type shaft trays, the cables are not separated, which makes it easy for heat to accumulate. Utility Model Content
