Electrical maintenance solutions

Regular maintenance is the key to protecting electrical turbine components - enhancing safety, increasing production, minimising downtime and ultimately maximising your ROI. Regular maintenance can also ensure compliance to manufacturers warranties and reduce the risk of component failure.

Appointing a dedicated team committed to looking after your electrical components throughout their operational lifecycle can ensure you achieve these benefits and help deliver maximum generation during high wind periods.

Planned service

A yearly or half-yearly service agreement with Swire will guarantee a systematic survey of all critical parts that concern the wind turbines grid connection. We undertake relevant tests, make the planned replacements and identify irregularities that may cause future problems. Everything is documented in reports which give a clear overview of the operational status of the turbine.
