High-frequency electrothermal capacitors

The LLC “PP” Termolit Plus “enterprise sells power electrothermal capacitors of the TERMOLIT-PLUS brand. They are designed and manufactured since 2011, using the most advanced materials, according to the latest technologies and meet all the requirements of international standards for electrothermal capacitors.

When manufacturing capacitors of the TERMOLIT PLUS brand, high requirements are imposed on the technological equipment and dielectric materials used. A film dielectric is used, the filler is environmentally friendly biodegradable liquids, which have replaced sovol.

High-frequency electrothermal capacitors

We create equipment for casting, heating, hardening, heat treatment of metal, equipment cooling systems. We design equipment, manufacture, carry out erection supervision, commissioning of equipment, train personnel.
We design and manufacture non-standard solutions for thermoelectric metal processing. In the production of components and assemblies for induction melting furnaces, we use high quality materials and the latest equipment and machines.

At all stages of production, the possibility of ionizing contaminants entering the capacitor sections is excluded, which can have a decisive effect on the dielectric qualities of the insulation and the technical characteristics of the capacitors. A temperature sensor is built into the design of our capacitors, which signals or removes voltage when the temperature rises above 60C

Advantages of Thermolit Plus capacitors:

  • Own production;
  • Assortment and low prices;
  • Product warranty;
  • Built-in temperature sensor;
  • Continuous availability of capacitors from 1000 to 8000 Hz in storage.

Use of capacitors

Power electrothermal capacitors are used in AC installations, in circuits with inverters and are designed to adjust the oscillatory circuits of induction melting furnaces and high-frequency electrothermal installations.

As an increase in power and heat dissipation, capacitors used at frequencies from 500 Hz to 66,000 Hz are manufactured water-cooled.

Operating conditions of capacitors

The installation of capacitors is carried out in those places that will not be affected by shaking and shock, on the insulating supports, taking the vertical position with all the leads up; a distance of 30 millimeters is maintained between the bases of the capacitors. In turn, capacitors with voltages up to 1000 volts are connected without special selection in capacity, no more than two.

Capacitors that are connected in series must be insulated and located in an insulating winding from each other. To lower the temperature of the electrical leads to common buses, each of them is connected separately.

Operating conditions of capacitors

When connecting capacitors to common buses and connecting terminals, we recommend using a flexible conductor to prevent damage in the soldering of fittings and insulators. To avoid overheating of the capacitor, it is necessary to check the heat generation in the wires and buses.

In order to reduce heating, water cooling of tires and wires is used. Ambient temperature should be from + 5 to + 45 ° С. The value of the relative air humidity is 95% at a temperature of 20 ° C.

To control the temperature regime of the operating condenser, flow and temperature sensors of the coolant must be installed, which turn off the condenser in case of a decrease in water consumption and an excess of the permissible temperature. Non-explosive environment that does not contain aggressive gases that reduce parameters even within unacceptable limits.
