2. Certificates we’ve got on RTU & FRTU

IEC61850 Certificate and DNP Certificate fromKEMA for DF1725 RTU


In November 2004, our DF1331 RTU pased the test of TNB of Malaysia


In July 2011, our DF1725IED RTU passed type test in ERTL(N)

3. Main Projects of RTU & FRTU In domestic market, our RTU&FRTU are

popular all over China. Until 2008, our RTU reached the market share of 70%.

3. Main Projects of RTU & FRTU

In 2005, we got the tender from TNB of Malaysia, 1267 sets of RTUs


In 2009, we got the contract for providing 20 sets of RTU for Greece Power Company and the first set of RTU is Accepted in 2010.


In February 2006, we won the bidder from JVVNL (Rajasthan India), to supply 45 sets RTUsIn May 2011, we got the tender of 47 sets RTUs from PSTCL (Punjab India). The first RTU had passed SAT now.
