What is diff between vcb and sf6?
SF6 (Sulfur Hexaflouride) is the god of gaseous dielectrics. It is a VERY poor conductor, and when it does decompose in an arc, it re-assembles itself in short order. It is also dense, so that it sinks to the floor, and pools in the lowest spot it can get to. This also makes it great in breaking arcs, because it makes it highly thermally conductive, stealing the heat from the arc & diffusing it. SF6 breakers are generally smaller than other types (of the same handling capacity), and therefore lighter. There's nothing we've found better with high voltage. Vacuum is decent. It has fair dielectric strength, can break an arc pretty well. It has one massive advantage over SF6: It is environmentally benign. SF6 is pretty destructive, and has a 3200 year life in the atmosphere. That's tenacity ! So, it has been suggested that if your application is below 36kv or so, you should stick with the VCBs, but you can't beat the handling of SF6 as you go higher.
What do you mean by acb and vcb?
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER
Can you use the vacuum circuit breaker instant of air circuit breaker?
Actually ACB isused for Low Tension side and VCB is used for High Tension Side..Chappa matter
What is the impedance for 110kV vacuum Circuit Breaker?
It should be something about 70 micro Ohm for VCB with two breaks per pole and about 30-40 micro Ohm for one break VCB

What are the differences between a vacuum breaker and a SF6 gas circuit breaker breaker and a sf6 gas circuit breaker?
vcb is have vaccume and sf6 cb is filled with sf6 gas which will have good arc quencing property
Why to use VCB in ht line side?
High current coming now that's why use the vcb

What is the major difference betwee vcb and acb?
vcb and acb
What is vcb?
The VCB yard us basically a yard that uses the Vacuum Circuit Breaker.

What is the difference in transistor between VCB and VCBO?
Vcb is what is measured in a particular circuit. Vcbo is the manufacturer's maximum for base-emitter voltage.
What is function of vcb?
VCB is Vacuum Circuit Breaker. It is one of the type of Circuit breaker. In VCB arching chamber is vacuum instead of oil or such arc quenching media. Its function is to break the circuit automatically in case of fault or to isolate the circuit under normal situation also.
What is the verb for civil?

How you can use vacuum circuit breaker in industry?
In Industries or any electrical commercial place can be use VCB for protection before the installation of equipment because or system of operation should be safe. Connection Firs Three phase wire will connect in VCB outdoor chamber R,Y,B then outgoing terminal will used in system supply
