6 FAQs about Circuit breaker in substation in Moscow

How many circuit breakers do you supply to Russia?

Over the years we supplied about 1.500 circuit breakers for voltage 110, 220 and 500 kV to the Russian market.

What type of Breaker is used in a substation?

Air blast breakers are generally used for voltages above 38 kV. Another type of circuit breaker that can be used in a substation is the oil circuit breaker. This type of breaker uses oil to quench the arc created when the contacts open. Oil breakers are typically used for voltages below 38 kV.

Who makes SF6 circuit breakers?

Dear Sirs, Let us introduce you company "Eurocontract" - a Russian company the main activity of which is production of SF6 high-voltage circuit breakers for 110-220 kV voltage class. During 10 years "Eurocontract" has been carrying out assembly as well as the complete cycle of electric and mechanical tests of this high-voltage equipment.

Why are circuit breakers important in a substation?

Circuit breakers are an important part of a substation because they protect equipment from damage caused by overcurrents or faults in the electrical system. If playback doesn't begin shortly, try restarting your device. Videos you watch may be added to the TV's watch history and influence TV recommendations.

What are the different types of MV circuit breaker?

There are three main types of medium voltage circuit breakers- air, oil, and SF6. Air circuit breakers use compressed air to extinguish the arc, while oil and SF6 circuit breakers use dielectric fluids to do the same. Oil circuit breakers have been around the longest, and were actually the first type of MV circuit breaker ever used.

What is eurocontract SF6 high-voltage equipment?

Thus "Eurocontract" provides the whole package of works and services during the processes of production, delivery and further fault-free operation of 110-220 kV SF6 high-voltage equipment for any customers at the Russian Federation territory.
