MAINTENANCE & SERVICE
Maintaining value through maintenance & service
Optimal protection
After purchase or lease, we are happy to maintain and service your transformer station, switchgear and more. Maintenance work is also carried out on weekends or holidays on request. This way you can avoid cost-intensive plant shutdowns!
What is most important to us? Optimal protection of your transformer station and low & medium voltage switchgear. This also includes electrical equipment such as circuit breakers, current and voltage transformers, isolators, supports, capacitors, cables and other components! Maintaining the value and extending the service life of your system is guaranteed by our regular, proper inspection and maintenance in accordance with DGUV.
The legislator has issued binding regulations for electrical engineering to ensure occupational safety. DIN VDE 0105-100 (“Operation of electrical systems”) and the DGUV regulation 3 (“Electrical systems and equipment”) of the employers’ liability insurance association clearly specify that the system operator must determine and specify maintenance intervals by means of a risk assessment.
We are familiar with all laws and necessities in order to provide you with full advice and support. With our service package HS-360 incl. maintenance contract, you can secure all the benefits and be rid of worries about your plant.
The HS-360 service package includes 360° support from consulting & planning to installation, maintenance & service.
