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.

Jointer working an LV termination inside an open roadside trench — heat-shrink kit, hydraulic crimping and full inventory laid out for a same-day re-energisation.

Sealing multi-run HV cable entries at a substation wall penetration — mechanical clamping, fire-stop mortar and cable-management dressing on new terminations.

Community-embedded jointing crew running PILC/XLPE terminations kerbside — full jointer's inventory, heat-shrink kits and hydraulic crimping tools staged.

Jointer preparing a copper conductor termination adjacent to a live transformer — cable-screen dressing, braid bonding and lug prep before the heat-shrink boot goes on.

Two-jointer team fitting a red HV heat-shrink stress-cone termination on an XLPE cable end — kerbside kit-up alongside an operational distribution kiosk.

Gas-torch application of a red HV heat-shrink boot over a fresh XLPE termination — controlled flame sweep for uniform recovery and full sealing.

HV cable coiled at the trench edge with sandbag ballast holding phase spacing — jointer positioning ends prior to termination and cable-mark verification.

Jointer cable-tying two parallel HV cable runs together at the base of the trench — spacing set, ties dressed and ready for the bedding sand and warning-tape layer.

Jointer working an HV termination at the base of a deep red-soil trench — shoring maintained, existing services identified and heat-shrink kit staged above the pit.

Finished HV cable joint dressed in the base of the trench — heat-shrink recovery complete, cable straightened around the existing steel service and ready for backfill sign-off.

Jointer in an open road trench dressing an LV cable termination on a shop-front kerb — timemark verified, tools laid to hand and reinstatement gang standing by for backfill.

Three red 12 kV Raychem elbow connectors seated onto the RMU bushings after a fresh XLPE termination — screen bonding checked, phase colouring intact, ready to close in.
