Why 33kv VCB Panel For Medium Voltage Distribution Systems?
In old days, oil circuits were used for medium voltage distribution systems but there were plenty of disadvantages of oil circuits. The major drawbacks were high flammable content and annoying maintenance costs.
This was the time to switch for better circuit breaker that can assure maximum efficiency and favorable results. Magnetic and air circuit breakers were also developed by manufacturers after oil circuit breakers but they were not so popular in market. They were cumbersome and bulky in nature.
Manufacturers were continuously researching for good circuit breakers product and finally vacuum circuit breakers came into existence. The performance of 33kv VCB Panel was so much pleasurable and it replaced the all other existing circuit breakers in market. This was the new generation circuit breaker that was compact and easy to maintain.
The vacuum circuit breaker is largely utilized for making or breaking loads and faulty currents. When current passes through circuit, it initiates the discharge in the arc that builds up dielectric strength strongly. The performance of 33 Kv Vcb Panel largely depends upon type of material used inside and level of contact.
From the years, plenty of materials are utilized for contact but only few of them are accepted under high voltage conditions and harsh environmental exposure. The best contact material for virtual circuit breaker is chromium that is finely distributed throughout the circuit in the form of grains. The use of chromium material makes current flow limited up to 5 Amperes only.
The high value of current is also controlled by the circuit and able to work with wide stress levels too. The chromium metal assures even distribution of heat and electricity throughout the whole 33kv VCB panel and successfully utilized in medium voltage distribution systems. Vacuum circuit breakers can also be availed in custom specifications with leading manufacturers and suppliers in India.
