Strong Power Electric has received a Certificate of Conformity from TÜV Rheinland LGA Products GmbH for its 27 kV three-phase outdoor automatic circuit recloser, model DVZ-800/27-16.
The certificate, Registration No. AK 50671726 0001, was issued on 7 April 2025, with the corresponding test report No. CN25EXWH 001. It covers a three-phase high-voltage outdoor AC automatic circuit recloser manufactured by Strong Power Electric Co., Ltd.
Why Is Third-Party Conformity Assessment Important for Recloser Projects?
Automatic circuit reclosers are key protection and automation devices in medium-voltage distribution networks. When a temporary fault occurs on an overhead feeder, a properly configured recloser can interrupt the fault current and subsequently attempt to restore the circuit automatically. If the fault remains permanent, the protection system can isolate the affected section according to the configured protection and reclosing logic.
In recloser tender projects, type test certification issued by internationally recognised organisations such as KEMA and TÜV is often an important technical qualification requirement. These certifications not only demonstrate that the recloser complies with relevant international standards and technical specifications, but also provide important evidence of the product’s safety, reliability, and long-term operating performance.
For utility projects, power grid applications, and distribution equipment tenders, reclosers with KEMA or TÜV type test reports are often better positioned to meet the technical qualification requirements specified by project owners and utilities. Selecting a recloser also requires consideration of system voltage, rated current, short-circuit level, insulation requirements and protection coordination.
About the TÜV Rheinland Certificate
The Certificate of Conformity applies specifically to the product and type designation stated in the certificate: DVZ-800/27-16. The certificate states that the tested specimen conforms to the assessment requirements identified in the document.
Strong Power’s DVZ-800/27-16 27 kV automatic circuit recloser was tested according to IEC 62271-111:2019 and IEEE Std C37.60-2018, as specified in the TÜV Rheinland Certificate of Conformity. meeting the relevant technical specifications for key performance aspects such as insulation performance, fault interruption capability, mechanical endurance, and operational reliability.
About the TÜV
TÜV is one of the internationally recognised names in independent testing, inspection and certification. Originating in Germany, TÜV organisations provide third-party technical assessment services for a wide range of industries, including electrical and power distribution equipment.
