SF6 gas has virtually replaced oil and air as the dielectric insulator in medium (MV) and high (HV) circuit breakers, switchgear, gas-insulated substations and electrical equipment. Despite SF6 being an inert gas during normal use, when electrical discharges occur by operation of high voltage equipment insulated with SF6,

2020-6-5Matching the MV circuit breaker to the task. Many years of experience in developing both SF6 and vacuum medium-voltage circuit breakers has yielded up ample evidence that neither of the

Rapid gas leak detection provides an early warning that gas is leaking and therefor maintains systems efficiency and reduces expensive gas replacement costs. The choice of output signals means the analogue signal can be set as 4-20mA, 0-20mA, 0-2V, 0-5V or 0-10Vdc for compatibility with almost any control system.

2017-8-22HV (high-voltage) and MV (medium-voltage) According to international standards like IEC, HV (high-voltage) is any voltage above 1 kV AC. MV (medium-voltage) is not fully defined in IEC. However, it is of common use that MV refers to voltages between 1 kV and 52 kV and that HV refers to voltages above 52 kV up to

2021-3-9Sulfur Hexafluoride (SF6) Gas The insulating and arc quenching medium -SF6 SF6 gas, previously used mainly in circuit breaker of higher voltage level and with successful achievements, has now been found into medium voltage load switching system in recent years.
