Renewable Energy - especially wind farms - is probably one of the main pillars of NAYTEX's activities, for more than 5 years already. That led us to re-organize a major part of our production line - supply of new equipment as well, in order to set NAYTEX as the leading Greek company in wind turbine repairs.
We have already performed countless repairs on wind turbines from 600 kW up to 3 MW. All works are accomplished with our high quality standards, in our fully equipped facilities, as mentioned above for each stage in repair process:
- Dismantling & Cleaning - intial stages of the whole repair process are performed in separate areas, in order to avoid any negative & harmful effects because of residual waste. We also collect & treat all these waste through our permanent installations.
- BURN OFF Procedure - old windings remove from the core, after BURN OFF oven treatment, without any harm to be caused and according to Internationl Standards. We are able to treat stators and rotors of almost any size, while keeping emissions at extremely low levels - after burner chamber with natural gas at 850oC.
- Tests & Measurements - all needed tests & measurements - megger, step voltage, high potential - according to International Standards (IEEE, EASA etc) are performed through new digital instruments, our custom made test apparatus (high power - AC & DC motors), only by authorized personnel in a dedicated area, where all safety rules are followed.
- New Coils “clean room” - all new coils, low & medium voltage, AC & DC, are made in a dedicated “clean room”, by skilled staff with special equipment & top quality materials, directly from major manufacturers all around the world.
- Varnish Impregnation & Drying - we can perform any method on varnish implementation, according to each repair requirements - VPI, dipping & potting. Drying procedure & moisture removal through two drying ovens. Varnishing / drying cycles according to International Standards.
- Machining & Side Works - NAYTEX can perform almost every needed work besides rewinding, including machining (even complex tasks & custom made constructions - hard chrome plating), balancing (two balancing machines - rotating parts up to 7 tones) & painting (separate paint area - with ventilation system & water sprinklers), in our workshop by our personnel, in order to supply top quality & strictly controlled services.
Renewable energy - all new developments in this field - particularly in wind power farms, inspired us to draw up an ambitious - five year development plan, in order to make a highly qualified part of our production line, that is already in progress.
