Power transmission service

Five offering groups cover the lifecycle. Consultancy and advisory assess the condition of transmission systems and plan the years ahead — asset condition assessments, lifecycle planning and digital-readiness reviews. Installation and commissioning bring new or retrofitted transformers and switchgear safely into operation, with testing and compliance checks. Repair and maintenance keep equipment at peak performance through preventive, time-based, condition-based and corrective work, plus emergency response, diagnostics and troubleshooting. Spare-parts services provide original OEM parts, smart-spares consulting and condition-based replacement strategies. Modernization and upgrade solutions raise capacity, efficiency and safety without full replacement — retrofit and refurbishment, control-system and cyber-security upgrades, digital enablement and lifetime extension.

Beyond individual interventions, long-term service programs bundle diagnostics, modernization and digital enablement into modular packages with flexible contract durations. A round-the-clock support team backs the whole portfolio, with defined response processes aligned to how critical each asset is, remote support and diagnostics for faster first action, and coordination across service, engineering and parts logistics. Servicing is offered for original equipment and, for maintenance, repair and spare parts, for third-party transmission equipment as well — so a mixed installed base can be maintained through one organization.

The same portfolio also carries the sustainability work the grid now demands: SF6-free switchgear using alternative gases, reuse and regeneration of insulating gas, biodegradable insulating fluids in transformers, and digital tools — condition-monitoring sensors, predictive-maintenance analytics and digital-twin models — that optimize grid operation while reducing losses and emissions.

Example: an operator running a mixed fleet of high-voltage switchgear and transformers begins with a condition assessment across the installed base. The assessment flags a few units for preventive maintenance now, one transformer as a candidate for a monitoring retrofit, and an ageing switchgear bay for a control-system upgrade rather than replacement. From that single lifecycle view the operator draws on the specific offerings in turn — spare parts for the maintenance work, a modernization scope for the bay, and a long-term program with defined response times to keep the whole fleet covered — all coordinated through one service organization, including for the third-party units in the same substation.

1. Start from the asset: identify the transmission equipment by type and, where available, serial number, so the right lifecycle stage and offering can be matched.
2. Consultancy and advisory — request a condition assessment or lifecycle plan when you need to understand where an asset stands and what it will need next.
3. Installation and commissioning — engage certified teams to bring new or retrofitted transformers and switchgear safely into operation, with testing and compliance checks.
4. Repair and maintenance — schedule preventive, condition-based or corrective work, or call the round-the-clock support team for emergency diagnostics and response.
5. Spare parts — request original OEM parts, smart-spares consulting or a condition-based replacement strategy for the units in your installed base.
6. Modernization and upgrade — plan retrofit, refurbishment, control-system or cyber-security upgrades and lifetime extension when replacement is not warranted.
7. For continuous coverage, wrap the above into a long-term service program with modular packages and a flexible contract duration; on registration, track requests and orders against your installed base in the shop.
