VALE – T3 Shaft Feeder Cable Installation
Included in this project was installation for two 750mcm/3c 15kv Airguard cable and grounding cables to increase the underground substation capacity. As part of the project, included was cable tray systems, and installation of multiple 15kv JBs on multiple levels in the mine. This project was extremely complex because of the aging shaft steel and the extreme weight of the cable down the shaft; all cable was installed from top down using special installation methods; the project was completed without any incidents. This project was managed directly by VALE.
