OVERVIEW OF CNCE

With total investment of 330million RMB, China National Quality Supervision and Testing Center for Mid-low Voltage Transmission and Distribution Equipment (abbr. CNCE), covers an area of 60 Mu, and the building area is 34500 square meter, With a 3500MVA impact generator, three 110kV substation, Short- circuit test ability  reaches  up to 12kV/65kA,1s and 450V/280kA,0.2s. It’s the first testing and research base of high, medium and low voltage electrical apparatus in South China and Southeast Asia。


QUALIFICATION OF CNCE

CNCE is accredited by the China National Accreditation Services for Conformity Assessment(CNAS)  as a high and low-voltage electrical apparatus laboratory。 It’s an international electrical commission IECEE CB-laboratory, and it’s also a "CCC" certification testing laboratory authorized by the Certification and Accreditation administration of the People’s Republic of China, a contractual "CCC" certification testing laboratory with  China Quality Certification Center (CQC) and voluntary certification testing laboratory of Power(Beijing) Product Certification Centre Co., Ltd. CNCE is also executing the testing work of Guangdong Testing Station of Product Quality Supervision for high-voltage transmission and distribution equipment. Testing capability of CNCE is accredited by KEMA in Holland, ASTA in England, State Grid,   China Southern Power Grid, China Nuclear Power, China Classification Society, China Railway Certification Center.  According to the customer's needs, the product tested by CNCE can be granted CCC, CQC, energy conservation, PCCC certification test report and CB,CE certificate, and foreign Netherlands KEMA, Britain ASTA, Germany VDE, Brazil UCIEE certification test reports. The clients will benefit from “one test for global market”.
