Alternatives for Cabling Support in 40 Floor Projects

In summary, the conversation discusses a project involving 40 floors and the use of cables from the ground floor to each of the floors. The designer recommends using expensive OZ / GEDNEY type S cable clamps with pozi-grip, but the person is looking for alternative options due to the long distance of the cable path. Non-conducting PVC tubing may be used for wire runs in commercial buildings, and support grips such as Hubbell-Kelems can be used if the conduit is interrupted and terminated every 60 feet. A box or covered cable tray must also be provided in these areas.

I have a project of more than 40 floors in height, in which the cables go from ground floor to each of the floors (1 tube 2-1/2" PVC + 4 conductors THHN 3/0 + ground in the higher floors ) The designer recommends the use of OZ / GEDNEY type S cable clamps with pozi-grip These supports are very expensive and I want to know what alternatives are there to support the cables since the path is long.

Welcome to the PF.

What country is this for? What electrical codes apply to these wire runs? Is it allowed to use non-conducting PVC tubing for wire runs in commercial buildings where you are?

If you may interrupt-and terminate- the pvc conduit all 60 ft [see NEC Table 300.19(A)]-4 floors about-you may use usual support grips -Hubbel-Kelems-for instance. A box or a piece of covered cable tray is to be provided in this place. See-for instance :

1. What are the common alternatives for cabling support in 40 floor projects?

Some common alternatives for cabling support in 40 floor projects include wireless networks, fiber optic cables, and powerline adapters.

2. How do wireless networks compare to traditional cabling in 40 floor projects?

Wireless networks offer the advantage of being more flexible and easier to install, but they may not have the same level of reliability and speed as traditional cabling in high-rise buildings.

3. Are there any specific challenges when using fiber optic cables for cabling support in 40 floor projects?

Fiber optic cables can be more expensive and require specialized equipment and expertise for installation. Additionally, they may be more susceptible to damage or interference in high-rise buildings.

4. Can powerline adapters be a viable alternative for cabling support in 40 floor projects?

Powerline adapters can be a cost-effective and convenient alternative for cabling support in high-rise buildings. However, they may not be as reliable or offer the same level of speed as traditional cabling.

5. What factors should be considered when choosing an alternative for cabling support in 40 floor projects?

When choosing an alternative for cabling support in high-rise buildings, factors such as cost, reliability, speed, and ease of installation should be taken into consideration. The specific needs and requirements of the project should also be assessed to determine the most suitable option.
