HV Switching & Maintenance

We provide certified high-voltage switching operations and preventive maintenance services for substations, industrial plants, and utility networks. Our technicians are trained in Operating Regulations for High Voltage Systems (ORHVS) and follow strict safety protocols to ensure reliable switching, fault isolation, and system restoration.

Our switching operations include planned outages, load transfers, fault clearance, and energization procedures — all executed with precision and documented for compliance. We use insulated tools, calibrated test equipment, and PPE rated for high-voltage environments. Every switching task is preceded by a risk assessment and switching program, ensuring safe execution and minimal disruption.

Preventive maintenance covers visual inspections, thermographic surveys, contact resistance testing, and insulation integrity checks. We service switchgear, circuit breakers, isolators, and protection relays, identifying wear and potential failure points before they escalate. Our reports include actionable insights and recommendations aligned with SANS 10142-1 and Eskom’s ORHVS framework.

Whether you're commissioning new infrastructure or maintaining legacy systems, our team ensures operational continuity, safety, and regulatory compliance. Trust us to manage your high-voltage assets with expertise and care.
