Product Overview

 

QCXE-35 Eco-friendly Gas Insulated Metal Enclosed Switchgear (C-GIS) are independently developed by our company. This series of products meets market demand and can use eco-friendly gas insulation or SF  as the insulation medium for metal enclosed switchgear (C-GIS) to meet the needs of different customers.
The QCXE-35 series switchgear has very high safety and reliability, which can ensure the continuous and stable operation of the power system and the personal safety of operators. At the same time, it also has a user-friendly operating interface, making it easy for on-site operators to operate. Rated voltage 35kV, rated current 630~3150A, rated breaking current 25~40kA.
QCXE-35 series switchgear adopts modern and innovative switchgear design concept, with a variety of functional modules to choose from. Commonly used functional modules are L, F, D, R, P, M, etc. Other modules can be customized according to the requirements of the primary system diagram when necessary. These functional modules can be installed on-site. Routine tests are carried out on all modules prior to shipment. No special tools are required to install these devices.
