6-10 kV Dry current-limiting reactors РТОС, РТСТ, РТСТГ, РТСТУ types

6-10 kV Dry current-limiting reactors РТОС, РТСТ, РТСТГ, РТСТУ types

Dry current - limiting reactors with natural air cooling are designed to limit short circuit surge currents in AC 50 Hz electric mains, with 6-10 kV rated voltage.
The reactors are connected in series with a power line and functioning as an additional inductive reactance to limit short circuit currents in electrical mains and maintaining the voltage level in case of electric short circuit.

The reactors produced by ELIZ LLC has the following advantages:

1. The reactors are designed for full short circuit current. The reactors design used a high-quality, high-temperature wire with polyamide insulation, that provides reactors operating temperature up to 180°C (Insulation thermal class H).
2. Compared with other reactors on the market, they have active material (windings) mass 10-20% more, which ensures reliable operation of the reactor under shock and thermal currents.
3. The design of the reactors is performed in the form of coils with a horizontal & vertical channel that provides the best conditions for the reactor cooling and improves its maintainability. These advantages can not be achieved using layered or cast coil reactors from other manufacturers.
4. When calculating the reactor a double (or more) reserve of the dielectric strength has laid, which allows the reactor to withstand of high switching or pulse surge.
5. Mounting node of supporting insulation made of high-quality insulating material with use of low-magnetic stainless steel, which can significantly reduce additional losses and overheating of the structural components, reduces mechanical (impact) influence on the structure in event of short-circuit.
