In the construction of high-rise building distribution trunk cable branch, according to the history of their development is divided into: plug-in busbar, cable distribution box, pre-branch cable and insulated puncture connector. The following are the same as the "
The following are the same as the "
1. Plug-in busbar: mainly used for large load distribution lines, the general high-rise building electrical shaft installed within the busway each layer has a plug connector, busbar after leaving the factory to be transported to the construction site with bolts To install the connection, and to ensure a moderate joint torque, the technical requirements of the installation of workers is high, and other busway in the waterproof, corrosion resistance, seismic, anti-displacement and other aspects of poor ability. The following are the same as the "
The following are the same as the "
2. Cable distribution box: This connection requires a larger construction space, high cost, complex construction and difficult, less reliable, easy to form a branch of the fault point. The following are the same as the "
The following are the same as the "
3. Pre-branch cable: Compared with the busbar, although the important light, small diameter, water resistance, corrosion resistance, good shock resistance, low environmental requirements, but the price is higher, special equipment to be hoisting, work. In addition, the pre-branch cable before the order of the construction of the actual size of the shaft (shaft height, height, each layer of the head position, etc.) to measure the factory and then according to the actual size of the production of pre-branch cable is not changeable. In order to avoid changes in the capacity of the floor due to changes in the capacity, the need to pre-branch cable trunk and branch sections are amplified one level, special circumstances should also be reserved for the spare line for spare. The following are the same as the "
The following are the same as the "
4. Insulation puncture connector: The connection has a simple installation, low cost, safe and reliable maintenance-free features. No need to cut off the main cable, no need to strip the cable insulation layer can do cable branch, the connector is completely insulated, can live work, you can
