GBE S.p.A. is specialized 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 S.p.A. 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 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 REACTORS:

These reactors 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 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 on the MV side.

 

SMOOTHING REACTORS:

The smoothing machines 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 REACTORS:

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