GIS GAS Insulated CE CQC CCC Certificates Metal Enclosed High Voltage Switchgear
Product Introduction
• It alludes to gas insulated switchgear operating at high voltages from 3.3kV to 170kV.
• It comprises of circuit breakers, earthing switches, protective relays and other apparatuses sealed within a gas insulated metal casing.
• The switchgear utilizes SF6 gas as an insulating and interrupting medium between the live parts operating at high voltage.
• The SF6 gas provides benefits such as a compact design, high reliability, less maintenance and a longer life span.
• The metal enclosed gas insulated design shields the switchgear from environmental factors including moisture, dust and pollution.
• It has procured various international certificates like CE, CCC and CQC, indicating it complies with relevant safety and performance standards.
• CE certification ensures the switchgear conforms to European Union health, safety and environmental protection requirements.
• CCC certification demonstrates the switchgear complies with China Compulsory Certificate system requirements.
• CQC certification signifies the switchgear meets Chinese quality control system standards.
• Strict safety procedures are followed to minimize risks during installation, operation and maintenance.
• The switchgear is suitable for applications in power transmission and distribution systems, industrial facilities, infrastructure projects and commercial buildings.
