Vacuum circuit breakers also known as VCB. They're a kind of circuit breaker in which the quenching of the arc takes place within the vacuum. They're suitable for medium voltage use. As opposed to air circuit breakers they do not use the mechanism to store air, but are dependent on electromagnet and an electric valve for their shutting and opening. They are therefore more costly over the air...

Electric motors transform electrical energy into mechanical force to be used in fans and pumps through the conversion of direct current (DC) or alternating current to magnetic fields that are used to drive shafts. Stator and rotor comprise two fundamental components in an electric motor. The rotor contains conductors which produce rotational force that is used for mechanical power while steel...

Chemical reactors are types of enclosed spaces where various chemical reactions occur. They are also known as processes vessels in chemical engineering. They can be used for many purposes such as making colorants and margarine. They are also used for the extraction of botanicals and purification. It's a reactor that is operated with both batch and continuous inputs as well as outputs. The main...
