Description

Technical Field

[0001] The utility model relates to the field of cable bridges, in particular to a ladder-type multi-specification cable common bridge structure. Background Art

[0002] Cable trays are widely used as a conventional installation structure for aerial cable installation. Cables are divided into 450 / 750v and below weak-current cables, 0.6 / 1kv low-voltage cables, 3-35kv medium-voltage cables, 35-110kv high-voltage cables and 110-750kv ultra-high-voltage cables according to different voltage levels. Under the requirements of cable installation technical standards, cables of different voltage levels and specifications must be installed separately for safety.

[0003] Existing cable trays have single-compartment and multi-compartment structures. The multi-compartment cable tray is mainly divided into multiple independent compartments by reasonably arranged internal partitions to lay cables of various voltage levels in different compartments to meet the requirements of safe use. However, the independent compartments in the current multi-compartment cable trays are generally of the same size and can accommodate the same number of cables. However, in actual applications, the situation is often that the number of high-voltage cables is small, while the number of low-voltage cables used for power distribution and diversion is large. This results in redundant space for laying high-voltage cables in independent compartments when using multi-compartment cable trays, and insufficient space for laying medium and low voltage cables in independent compartments. It is difficult to place cables of different specifications in a suitable accommodation space.

[0004] Therefore, for the above-mentioned existing equal-capacity multi-compartment cable tray, the compartment structure is divided in a single way, the number of cables of different specifications varies greatly, and it is difficult to place cables of different specifications in a suitable storage space. A cable tray with a stepped compartment structure can be designed. By improving the existing ordinary single-compartment cable tray, a detachable stepped compartment structure is set up, and different independent compartment spaces are reasonably divided, which helps to place cables of different specifications in a suitable storage space.
