Delivered on live infrastructure — often track-side, at night, under load. A cross-section of recent work across South Africa's utility, transport and enterprise networks, geo-verified on site by our crews.

OHTE mast maintenance — Metrorail corridor
Past jobs completed

Site-verified work, filtered by discipline.

Every card is a real Musi crew on a real site — timemark verified, matched to the service that delivered it. Drag or use the arrows to scroll.

Ground reinstatement and cable bedding at a live distribution substation after HV cable replacement — transformer bank kept in service throughout.

Removal of a burnt-out mini-substation kiosk and prep of the plinth for the replacement unit — HV disconnection, earthing recovery and safe rig-down.

Live substation transformer bay with a hand-dug trench and multi-run HV cable lay-in — bushings, disconnectors and cooler fans kept in service during the tie-in.

New indoor ring-main-unit switchgear staged at the substation door ready for roll-in — bushings capped, mechanism sealed and delivery paperwork signed off.

Hand-carried lay-in of a new HV cable from the trench across to the transformer bay — team spaced along the run to control bend radius and side-load.

Withdrawable vacuum circuit-breaker pulled out of the switchgear cubicle for maintenance — bushings capped in red, spouts exposed and racked out onto the trolley for testing.

New LV feeder cables run out of the transformer bank onto a brick plinth with sandbag ballast holding phase spacing — ready for terminations and re-energisation.

Substation basement cable-basket run with multi-phase HV and LV cables dressed in parallel, cable-numbered and cleated — clean feeder make-up ready for switchgear tie-in.

Fully commissioned MV and LV switchboard line-up on a blue epoxy floor — indication lamps live, danger-HV labels affixed and control gear tested ready for hand-over.

Three-technician team running a transformer ratio and winding-resistance test on a 50 kVA 11 kV/400 V mini-substation before crane-lift back onto its plinth — results logged on the clipboard.

Full four-panel LV switchboard (P1–P4) energised and live — ACB draw-out breakers racked in, indication lamps proving, danger-HV placards fitted and hand-over paperwork on the doors.

Doors of a mini-substation opened to expose the transformer radiator bank and off-load tap-changer at the 100% / 120% positions — pre-energisation inspection before final commissioning.

Pole-mount 200 kVA distribution transformer slung under the Palfinger boom for a live-swap into an aged reticulation feeder — HV bushings, LV terminations and lightning arrestors pre-fitted for a same-shift energisation.
