Vt3cx4500f3 air-cooled triode is a power triode with medium amplification factor, forced air cooling, thorium tungsten carbide cathode and cermet structure. The maximum anode dissipation power is 6kW, the maximum grid dissipation is 300W, and the maximum operating frequency is 75MHz. It is mainly used as amplifier, oscillator or modulator, and can obtain high power output at medium voltage. It can be interchanged with 3cx4500f3/ yu108 electronic tubes produced by eimac company of the United States.
In industrial applications, the filament of the tube is led out by flexible wires, and the grid is connected with the equipment by a solid flange.
