Bridge connection

Cross Connection Cabinet Installation

Cross Connection Cabinet Installation is to put the two ends of the bridge to be linked together, and use special connectors for grid bridges to connect.

If the length of the straight section of the bridge is more than 3m, the mesh bridge can be used with its own buckles, which can be directly linked without using additional connectors. There are many types of special connectors, including quick connectors, common connectors and combinations of various connectors.

Parts production

Various angles of corners, tees, crosses, diameter reduction, elevation changes and other components are produced on site. Use wire cutters to cut off part of the grid of the straight section grid bridge, then bend and form, and connect with special connectors Assembled into various parts.

Cable binding inside the fiber Cross Connect Cabinet

The cable laying of the Cross Connection Cabinet, as the permanent link of the system, the cable laying path, cable binding, cable pulling depth, winding degree, etc. directly affect the electrical performance of the cables used in the later stage and the whole value of engineering.

The traditional construction method places the cables directly in the metal bridge, and occasionally bundles the cables. Due to the dense cables in the equipment room, after the construction is completed, the cables are in a mess in the bridge, and the direction of the cables cannot be clearly seen. Especially at the corners, the cables are unreasonably stretched and many cables overflow the bridge. After the second addition of cables, the cables have no rules at all.

In this project, the Cross Connection Cabinet and the fixed cable organizer are used to fix the cables in groups of 12 horizontally on the grid tray, and the cable organizer is used to make the horizontal twisted pairs enter the network room regularly and in parallel for wiring. In the future, when the line is expanded, a large number of cable changes will not be caused by changing one cable, so that the overall reliability is guaranteed, that is, the expandability of the system is improved.

Detailed design

The weak current system networks such as data voice, security, monitoring and building equipment control in the building intelligent project are built on the basis of integrated wiring to realize information sharing and centralized monitoring.

Therefore, the specifications and models of the grid bridge should be determined according to the different uses of the cables, the direction of the cables and the number of cables, and should be clearly marked in the construction drawings. Determine the cable entry method and grid tray specifications of the fiber Cross Connect Cabinet in the equipment room. Carefully study the structure and decoration characteristics of the project, determine the layout position of the vertical bridge system and the horizontal bridge system, determine the three-dimensional positioning, size, and laying method of the grid bridge (wall, ceiling, floor underground, no ceiling position, etc.), brackets , The form and spacing of the hanger, the turning angle, the change of the tee, the cross and the elevation, etc.

Preparation of plans and measures

According to the in-depth design drawings, the construction organization design, key process technical plans and safe and civilized construction measures are prepared.

Investigation of construction environmental conditions

The work area, telecommunication room and equipment room need to have all the civil structures completed (only the pre-embedded pipes and the civil structures are carried out simultaneously), which meet the design requirements and the environment is clean and tidy.

Preparation for installation of equipment

Cross Connection Cabinet Installation

According to the prepared plans and measures, prepare the human resources, material resources, construction equipment and measuring instruments required for the construction.

Preparation for installation of equipment

After the materials and equipment required for the project enter the site, firstly carry out the quantity inventory and damage inspection of the outer packaging, then check the materials and equipment qualification certificates, factory quality certificates and other documents, and finally conduct random unpacking of the materials and equipment. detection. Only the materials and equipment that have passed the inspection can go through the warehousing procedures and finally be put into use in the project.

Fabrication of brackets and hangers

The form of support and hanger is determined according to the size of the fiber Cross Connect Cabinet, the weight of the bearing cable, and the laying method. Support and hanger forms include support arm type, middle suspension type, two side suspension (gantry hanger) type, floor type and so on.

Bracket installation

Determination of Spacing: The spacing between horizontal mounting brackets and hangers of the straight section of the Cross Connection Cabinet is determined according to the material, size and weight of the cables of the Cross Connection Cabinet. The distance between the supports and hangers should be 1.5-2.5m, and the level deviation in the same horizontal plane should not exceed 5mm/m.

To ensure that the level deviation of the fiber Cross Connect Cabinet meets the specification requirements, the weight of the cables to be laid must not exceed the maximum load capacity of the fiber Cross Connect Cabinet.

When the support and hanger are installed, the positioning of the cable should be measured (using an infrared meter, etc.) to determine its orientation, height and levelness.

Fabrication of fiber Cross Connect Cabinet

Cross Connection Cabinet Installation

All kinds of components are produced on site by using straight-line segment grid type bridges, each grid size is 50x100mm. When making, it is necessary to use wire cutters to cut off part of the mesh. After cutting, the sharp edge of the mesh is smoothed to prevent the cable from being worn.

When making an elbow, first determine the outer and inner sides of the elbow, and then cut the side and bottom meshes of the straight segment fiber Cross Connect Cabinet that becomes the inner side of the elbow. When cutting, only the transverse ribs are cut, and then assembled with special connectors into an elbow.

The tee is divided into horizontal 90° tee, horizontal 45° tee, vertical 90° tee, and vertical 45° tee.

When making a horizontal 90° tee, cut a number of grids from the lateral bars on the outer side of the trunk fiber Cross Connect Cabinet, and then use connectors to connect the branch grid bridge to the trunk grid bridge to assemble a horizontal 90° tee.

When making a horizontal 45° tee, cut a number of grids from the lateral and vertical ribs on the outside of the trunk and branch lines of the Cross Connection Cabinet, and then use connectors to connect the branch line bridge to the trunk grid type bridge to assemble a horizontal 45° tee.

When making a vertical 90° tee, cut a number of grids from the transverse rib on the bottom side of the trunk Cross Connection Cabinet, and then connect the branch Cross Connection Cabinet to the trunk grid bridge with connectors to assemble a vertical 90° tee.

When making a vertical 45° tee, cut a number of grids on the lateral bars and vertical bars of the trunk and branch grid bridges, and then connect the branch grid bridge with the backbone grid type bridge with connectors to assemble into a vertical 45° tee. .

The 90° tee is used for laying cables with a small bending radius, and the 45° tee is used for laying cables with a large bending radius.

Laying of electric cables

Cross Connection Cabinet Installation

The laying of cables must be completed after the construction of the conduits, bridges, etc., which are routed, and the inspection and acceptance can be carried out. Before laying the cables, protect the conduits and places that may cause damage to the cables during the cable laying process; then determine the positions of the cable trays and wire boxes, and then lay the cables to each end.

Arrangement of cables

After the cables are laid to the designated information points, every 12 cables are in a group, and 6 cables are in a group, and they are fixed on the grid bridge.

The spacing between the cable management boards (adjacent spacing) can be installed according to 30cm, 50cm, 70cm and 100cm.

After 12 cables are laid, cable fixing and Cross Connection Cabinet Installation must be carried out immediately. Cable crimping must start from the starting position of the cable and then crimp to the floor wiring room in sequence. An additional processing board is required at the corner of the cable. When crimping the cable, pay attention to the tightness of the cable at the cable crimping point and the turning radius of the cable.

Benefit Analysis
