Grand Power River Co., Ltd.
Grand Power River was founded in 1994 by a team of engineers with over twenty years of manufacturing and design experience in the distribution transformer industry. Their goal was to bring new products to market that were the highest quality with the lowest waste of energy over the life of the product. At the same time, GPR developed a close relationship with the manufacturer (Allied Signal) of the very low loss amorphous material used in the manufacture of the low loss amorphous core transformer. In August, 1995, GPR began the successful sale of amorphous core distribution transformers. The first 19 units were shipped to customers in Japan. These were the first amorphous distribution transformers produced in Taiwan. Since that beginning, GPR has shipped over 600 AMDTs to Japan. Allied Signal supplies the amorphous metal transformer core used in GPR ultra-efficient amorphous metal distribution transformers. This leading edge core technology combined with US manufacturer coil design techniques and manufacturing technology enable GPR to be able to make transformers with very high mechanical strength to withstand the stresses of operation and have very low energy loss to reduce the operating costs. The amorphous metal distribution transformers (AMDT) are sold under the trade mark Metglas-Trans in Japan and Green-Amtrans in Taiwan and other countries. The GPR AMDT can be obtained in ratings from 10KVA to 1000KVA single phase and 30KVA to 4000KVA in three phase. The high voltage rates up to 33000V.
