Resin & Oil Reactors In Ireland

At GBE Engineering Systems, we are specialised in producing class F or H VPI, cast resin and oil reactors for indoor and outdoor applications up to 5000 A/52 kV.

For outdoor applications, GBE Engineering Systems can supply cast resin reactors even without the protection box, thanks to the use of resin and special UV-resistant coatings.

Current Limiting / Short Circuit Cast Resin & Oil Reactors

The current-limiting reactors are used to limit the line current. They are normally used to ensure that the current does not exceed the values allowed by the protections in the event of a failure. They are connected in series with the line.

They are single-phase coreless coils, three-phase connected one above the other, or provided individually and locally, three-phase connected

Earthing Cast Resin & Oil Reactors

Typically made in oil, they have a three-phase core with zig-zag winding. This type of reactor is used to create a false neutral directly connected to ground or through a resistor. The neutral formers are shunt-connected to the line.

Filter Cast Resin & Oil Reactors

These are single-phase or three-phase reactors used to reduce the harmonic content in the grid or inside plants with high voltage distortions. They are connected in series or in parallel to the capacitors on both the LV side and the MV side.

Shunt For Cast Resin & Oil Reactors

The shunt reactors compensate for the capacity of the long transmission lines, avoiding voltage rises at the end of the same line and are shunt-connected to the line.

Smoothing Cast Resin & Oil Reactors

The smoothing reactors are connected in series to the DC line, where there is a current ripple that must be reduced. The smoothing reactors are typically single-phase.

Detuning Cast Resin & Oil Reactors

These are reactors connected in series to capacitors, which allow the resonance frequency to be moved to a value that is not dangerous to these capacitors.
