About the CTK 30-2
The CTK 30-2 is a power triode manufactured by Thomson / Thales. Thales high-power coaxial metal-ceramic triode with water-cooled anode, positioned between the CTK 25-4 and CTK 35-2 for industrial RF and laser duty.
Key ratings of the CTK 30-2 include tube type Triode, construction Metal-ceramic coaxial, anode cooling Water, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are CO₂ laser cutting oscillators, industrial RF heating, high-power RF amplifiers, plastic welding and induction hardening. Notable features: high-power CTK series, water-cooled anode, metal-ceramic coaxial and thorium tungsten cathode.
Power triodes are three-electrode grid tubes used as RF oscillators and amplifiers in industrial RF heating (plastic welding, induction heating, drying), RF-excited CO₂ lasers, broadcast transmitters and particle accelerators. In oscillator service they work with vacuum capacitors in the tank and matching circuits.
