Bolted Cable Spacer
This bolted cable spacer is an aluminum spacing fixture used to maintain electrical cable clearance.
The main application of this product is to provide cable clearance for slack spans for substations. Slack spans are popular components of electrical power lines and suspension bridges.
The Cable Spacer Aluminum consists of four key components. These components include two parallel aluminum bars with cable slots on both ends and two bolts and nuts. The spacing of this particular cable spacer is 4 inches.
The primary function of the Cable Spacer Aluminum is to provide and maintain clearance between cables. It also helps improve structural flexibility.
Electric cables are assembled in the slots. Then, the two aluminum bars are attached and fastened with bolts and nuts. This installation ensures the two cables are properly spaced to provide the required clearance.
Electrical engineers use this bolted cable spacer with slack spans. Key accessories used in the installation of bolted cable spacers are a screw wrench and motor plate.

Frequently Asked Questions
What is a Bolted Cable Spacer?
Cable Spacer Aluminum is a cable spacing fitment installed on slack spans of electrical power lines.
Components and Assembly of Bolted Cable Spacers
This cable spacer features two aluminum bars with bolt holes on both sides. Two bolts and nuts are used to screw the bars together. The aluminum bars have cable slots on both ends. There is a spacing between the cable slots. When fully assembled, a gap remains between the two bars.
Key Applications of Bolted Cable Spacers
The manufacturer says this product is suitable for slack span applications. However, it should only be used for substations and not overhead transmission lines.
How a Bolted Cable Spacer Works?
The compatible conductors are positioned in the parallel cable slots. Then, the two aluminum pieces are assembled and held together with the provided bolts and nuts. The spacing between the cable slots provides the expected clearance. It also provides support for the conductors, helping prevent damage to loose cables and improve structural flexibility.
What are the Key Features of Bolted Cable Spacers?
The cable spacer has an aluminum construction, which is mainly recommended for use with slack spans. It provides a spacing of 4 inches and supports a 0.870 to 1.108-inch conductor diameter range. Additionally, the Cable Spacer Aluminum is a good fit for ACSR and AAC conductor types.
