Fortis was commissioned to install 2 feeder cables, 2 ground cables, 2 fiber optic cable down two 8″ boreholes 500 + Meters deep. These cables feed an underground substation in a mine. Fortis custom designed and tested cable clamps which combined and supported the sacrificial support cable, fiber optic cable, ground conductor and 25Kv Verlock feeder cable. Cable assembly was suspended by a Northern Strands 20T Suspension Gland on a Fortis custom designed Sheave Stand Assembly which also included (3x) terminations for the internal tensile support members of the Verlock feeder cable. The cable bending radius’s had to be carefully accommodated. Also a suspended load capability of 30,000 lbs had to be incorporated into the equipment design. As a result Fortis designed and built a wire rope sheave stand assembly to perform the task. See picture below. The job went very well, it was completed safely and ahead of schedule.
