About Our Industrial Electrical Installation Service

Industrial electrical installations are complex, high-stakes projects that demand a level of expertise, planning, and execution far beyond standard residential or commercial work. Andrex Electricals Systems has the technical capability and on-site experience to deliver complete industrial electrical systems for factories, manufacturing plants, warehouses, food processing facilities, and large commercial buildings. We work to internationally recognised standards, including BS 7671 and BS 7430, and our engineers produce full documentation packages to support regulatory approval and commissioning sign-off.

Power Distribution & Switchgear

At the heart of any industrial facility is its power distribution infrastructure. We design and install main incoming switchboards, sub-distribution boards, motor control centers (MCCs), and power factor correction panels. Our panel-builders assemble switchgear to exacting standards, with every busbar, breaker, contactor, and relay correctly sized and labelled. We work with both low-voltage (LV) and medium-voltage (MV) systems, and our team is experienced in coordinating with Kenya Power for large supply connections and transformer installations. Properly designed power distribution is essential not only for safety but also for operational efficiency — undersized or poorly planned systems lead to costly downtime and maintenance issues down the line.

Three-Phase Wiring & Motor Controls

Industrial machinery and equipment typically runs on three-phase power, and the wiring of these systems must be precise and robust. We install three-phase distribution systems, direct-on-line (DOL) starters, star-delta starters, variable frequency drives (VFDs), and PLC-controlled motor control systems. All wiring is carried out to manufacturer specifications, with correct cable sizing, termination standards, and labelling throughout. We also install cable trays, cable ladders, and conduit systems to organise and protect all power and control cabling within the facility, keeping the installation accessible for future maintenance and modifications.

Industrial Lighting, Earthing & Generator Systems

Large industrial spaces require specialised lighting solutions. We supply and install high-bay LED luminaires, floodlights, emergency lighting systems, and hazardous area lighting where required. Our earthing installations are carried out to BS 7430 standards, with soil resistivity testing, electrode sizing, and full documentation to support compliance audits. For facilities that require standby power, we install and commission diesel generators, automatic transfer switches (ATS), and synchronisation panels — ensuring your operations continue uninterrupted during grid power failures.

Maintenance Contracts & Ongoing Support

Industrial electrical systems require regular inspection and preventive maintenance to operate safely and efficiently. We offer tailored maintenance contracts that include scheduled inspections, thermographic surveys to identify hot spots before they cause failures, testing of protective devices, and emergency call-out support. Our clients benefit from a single point of contact for all their electrical maintenance needs, with response times guaranteed under their service agreement. Preventive maintenance significantly reduces the risk of unplanned downtime and extends the service life of electrical infrastructure.
