Powering a palm oil mill: LV switchboards, power factor correction & heavy-duty cabling
A palm oil mill runs almost non-stop in peak crop — so the electrical backbone is a production asset, not a utility. This project delivered a 415 V main switchboard, a process-floor sub-switchboard, automatic power factor correction at both, and the heavy-duty cabling that ties them together.

What this project involved
Fresh fruit bunches lose grade with every hour of delay. Sterilisers, threshers, digesters, presses, clarifier pumps and boiler fans all stop when a board trips — so LV distribution has to be designed for heat, fibre dust, large motor swings and maintenance without shutting the whole mill.
We delivered the low-voltage side of a working palm oil mill: a floor-standing 415 V main switchboard in a dedicated switch room, a wall-mounted sub-switchboard on the process floor, automatic power factor correction at both boards, and parallel single-core copper cabling with full R/Y/B/N identification.
Main switchboard (MSB)
The MSB sits away from process dust and moisture. Sections cover automatic power factor correction with step indication and louvred cooling, MCB chassis for lighting and control, MCCB outgoing feeders with lockable handles for safe isolation, plus digital metering at the incomer.
Sub-board, PFC and cabling
Closer to the machines, the process-floor SSB distributes locally and corrects power factor at the point of use, with orange trunking for tidy containment. Inside the MSB, parallel single-core feeders rise from trench entry to busbar terminals — phase-sleeved, earthing-strapped and segregated from the live chamber so technicians can read the board at a glance.
Why Wiring & power
This sits under Wiring & power because the deliverable is industrial LV distribution and power-quality hardware, not generation. See power factor correction, 3-phase power, and the full project insight.
