CDL8 Series Indoor Cubicle-type Gas Insulated Switchgear (C-GIS)
CDL8 series indoor cubicle-type gas insulated switchgear, called as C-GIS, is a kind of product which accords to the international advanced technique. Such as solid insulated, gas insulated, VCB and modular plug board, Combining the new He leak-check. The product has high reliability, maintenance-free and miniaturization etc.
■ Ambient temperature: 一Max. +65 °C 一Min. (indoor) -40°C
■ Site altitude: not more than 4500m
■ Ambient air: The ambient air is not to be significantly contaminated by corrosive, flammable gases or salt etc.
■ Earthquake intensity: less than 8 magnitude
Note: Site altitude more than 2000m are to be agreed by the manufacture and operator.
■ Adopting gas insulated for high voltage electrification components, independence to environment influences.
■ Structure compact, minimum space required.
■ Adopting interface insulated structure, realizing high voltage electrification components insertion and switchgear extension.
■ Adopting the effective interlocking between circuit breaker and the three position switch, preventing from mishandling.
■ HV components constitutes some standard modules, adopts plug-in connection, application convenient.
■ Adopting the solid insulation plug-in busbar connector, it is not need any gas operate. When connecting between cubicles.
■ Technology of the laser weld and He Leak-check is applied, high reliability.
