5x6B Gas Turbine Power Plant Founded on October 8, 1991, NG is a well-established Sino-foreign joint venture located in Shenzhen SEZ (Special Economic Zone). It's a subsidiary of NTC NTC is a company to co-manufacture heavy gas turbines under the TTA agreement of GE. At present, NTC is manufacturing and selling 6B.03/6F.01/6F.03/9E.03 heavy-duty gas turbines. NG main business scope covers areas such as equipment package, installation, commissioning, custom modification & upgrade (CM&U), inspection and overhauling for gas turbine and steam turbine power stations. As the sole distributor of GE gas turbine spare parts in China, NG can provide GT spare parts with best quality and most favorable price. Meanwhile, NG also can provide domestic tightening hardwares, seals and some auxiliary spare parts needed in unit installation and overhauling. NG possesses a strong professional team with rich experience and proven competence in gas turbine genset installation and overhauling, and possesses high-tech instruments and facilities for GT inspection and overhauling as well. NG has so far been the only eligible EPC company in China for both GT spare parts supply and GT projects contracting including GT power station overhauling, CM&U, overseas relocation, installation and commissioning. In spite of numerous difficulties such as incomplete documents and insufficient equipments, NG has successfully undertaken quite a few GT projects such as the old used GT unit removal, installation, overhauling, commissioning, liquid fuel upgrade to gas for fuel and control system, GT performance test and operation services for GT power station. EPC work covers CM&U design, type selection for imported spare parts, import agency, production of domestic parts, special parts preparation and site construction as well as personnel training. our company has 5 used 6B gas turbines and we can sell 5 GT UNITS to you because several other companies are interested in these 6B gas turbines. If you are interested, please contact me immediately.
