High Voltage Switchgear is used for systems above 36kV. Ceho can provide not only high voltage but also low voltage switchgear, as well as a complete set of electrical equipment including transformers and substations.We have a wealth of experience, professional team is the basis for supporting us to provide customized configuration solutions, you can also contact us for technical support services.
Safety is very important for any electrical equipment, and Ceho also takes safety into account in the design process and does not make hasty design.
1) Metal shell design: bus, circuit breaker and cable terminal adopt isolation compartment to prevent internal arc diffusion.
2) Arc resistant structure: safely direct arc impact energy away from personnel, generally tested in accordance with IEEE C37.20.7 standard.
3) Comprehensive interlocking device: avoid wrong switching sequence.
4) Safety grounding: The grounding switch is firm and the grounding terminal is clearly visible.
5) Pressure relief system: especially considering the case of gas-insulated switchgear, it is equipped with a safety exhaust port to exhaust gas when internal faults occur.
6) Clear, non-removable warning labels and illustrations.
IEC 62271 Series: The comprehensive International Electrotechnical Commission standard for high-voltage switchgear and controlgear.
IEEE C37 Series: The Institute of Electrical and Electronics Engineers standards, widely used in North and South America.
ANSI Standards: Often referenced alongside IEEE standards for ratings and testing.
Local Grid Codes: Specific requirements from transmission system operators (TSOs) or distribution network operators (DNOs).
