Supply and exhaust ventilation
Very often in dirty industries, dust clogs mechanical contacts (poor contact, sticking). The use of a contactor with a closed control board prevents the failure of electrical equipment and downtime of production in general.
Сonveyor belts
Screw conveyors
In industries where a screw conveyor is used, dust clogs mechanical contacts (poor contact, sticking). The use of a thyristor contactor with a closed control board prevents equipment failure.
Сrushers
TK-200A for Norilsk Nickel for ore crushers
Long-term use of the equipment caused the failure of mechanical contactors due to the peculiarities of the technological process of grinding ore. The supplied thyristor contactors have been operating for more than 10 years.

Oil and gas industry
Pump stations for pumping oil and gas
A prototype TK-250A for a 0.4 kW pumping station for the Ufa Oil Refinery
The system control of pumps during oil pumping is connected with the system control via a computer. The response time of the KT contactor is 0.5 s, the response time of the thyristor contactor and the computer is 0.01 s. In case of emergency shutdowns, the CT does not have time to turn off the pressure of the oil column in time; there is no failure with the thyristor contactor (TC). In winter, condensate accumulated from the heating of mechanical contacts, which led to the failure of the CT, this does not happen with the TC, since there is no mechanical contact.

Metallurgy
Furnaces
Modernization of Kemerovokhimmash furnaces
Maintaining a temperature regime with a tolerance of 1 degree requires a high frequency of switching on and off, which leads to an early failure of the electromechanical contactor due to sticking of the contacts. The thyristor contactor works on the principle of a contactless key, therefore it has an almost unlimited on / off frequency, which eliminates the problem.

Tube rolling electric drives
Simultaneous exposure to dust, dirt and temperature leads to wear of the mechanical parts of the CT. In thyristor contactors (TC), this is excluded, since the temperature operating modes of the TC are from -60 ° С to + 120 ° С
