Roxtec’s Modular Substation Cable Termination Design white paper discusses the methods for cable penetrations into modular industrial substations and the requirements for structural and environmental integrity, grounding, fire protection and ease of expansion for a cable termination system. Current methods of installation are compared to using a cable transit design for installing and terminating cables in electrical substations.

Excerpt:

Modular substations are becoming the preferred approach for installing electrical and control equipment in industrial facilities. The ability to prefabricate a building, pre-install both electrical and control equipment and the ability to pre-commission equipment prior to the installation helps to reduce on-site construction installation costs. This is particularly advantageous in remote project locations where the cost of labor can be very high.

The on-site termination of conductors and cables into equipment can often be an issue. The equipment layout, the design of the modular building skid base frame, the number of terminations and the termination method can all influence the speed and ease of installation. Choosing the wrong penetration approach can compromise the environmental integrity of the building and…>>Read More
