Whitepaper | Modular Cable Termination Design By Roxtec
October 12th, 2020
Abstract
The methods for cable penetrations into modular industrial substations are summarized.
The requirements for structural and environmental integrity, grounding, fire protection and ease of expansion for a cable termination system are discussed.
Current methods of installation are compared to using a cable transit design for installing and terminating cables in electrical substations.
Introduction
- Modular Substation Fundamentals
- Terminating Cables In Substations
- Traditional Cable Termination Options
- Improved Cable Termination Option Using A Cable Transit System
- Work Process
Hazardous Areas & Explosive Atmospheres (Gas & Dust) | Ex e and Ex tb Explosion Protection Certified by ATEX & IECEx | Zone 1/21 & Zone 2/22
Conclusion
Roxtec modular cable transit seals are based upon a rubber design with seals that are constructed of a number of removable layers to secure a watertight, gas tight and fire proof seal around the cable or pipe – the range includes rectangular transits and round transits to fit a variety of pipes and cable sizes.
