High-Voltage Component Testing

Power contractors are always looking for ways to expand their business into international markets with contracts for overseas power engineering projects. At the same time, domestic power engineering also needs to follow international standards and regulations for design and construction.

High-voltage component safety and quality are essential to operations of entire power systems. TÜV Rheinland has extensive experience in the field of high-voltage components and a top-class global service network. We also provide domestic high-voltage component manufacturers with local one-stop services.

We help you understand which international standards are relevant to your business requirements and offer testing and certification services that help to enhance the competitiveness of your products in international markets.

With TÜV Rheinland as your partner for testing and certifying your high-voltage components, you benefit from the following:

• Through cooperation with various high-voltage apparatus research institute, for instance in China, with XIHARI, we can provide one test for various standards (e.g. IEC, EN, GB, DIN, ANSI, IEEE etc.) to help you gain a foothold and access in multiple markets
• A shorter period for testing and certification guarantee
• Local engineers for easier and faster communication and technical exchange with no language barriers
• Support for companies in production process supervision and quality inspections, and inspection reports
• Tests are done and reports issued according to customers' technical requirements

TÜV Rheinland offers the following test reports and certificates for high-voltage components:

• One test in Mainland China, issue of GB* and IEC(CB)report
• Test reports based on other standards, such as EN, ANSI, IEEE, SNI and GOST Test reports
• Inspection and audit(Quality Assurance)
• On-site witness test
• CE certificate and Energy efficiency for Power transformers
• Special test and service like: Seismic, Environment, Corrosion and Vibration etc.
• International approval: GOST, SNI, SABS, INMETRO, RETIE etc
• TÜV type test certificates and international recognized CB** report

*GB: China mandatory national standards. High-voltage electrical appliances that enter the Chinese market must have a GB or GB/T standard test report.

**CB: IECEE Member States certification body based on the IEC standard electrical product safety testing: the test results are CB test report and CB Test Certificate under the IECEE Member States mutual recognition system. The certification is intended to reduce barriers to international trade and to meet different national certification or approval criteria. The IECEE International Electrotechnical Commission IEC product qualification testing and certification organization currently has 55 member states.
