Since 2008 KPM, LLC has been carrying on successful business in the field of development and production of dry electric reactors of various purpose. 

Patented design (Patent No. RU 156365 U1), availability of extensive production capacities, and continuous investments into scientific research enable the company to hold one of the leading positions in the industry. The enterprise constantly develops and embraces new technologies and product types.

To date we have a proven experience in production of reactors rated for voltage of up to 330 kV, incl., for current of 50 to 5000 A, and coupled current-limiting reactors rated for up to 2х4000 A. We have produced more than 7200 phases. We have vast practical experience.

Proven home-produced components and quality system with operation-wise monitoring at each production stage enable us to provide our customers with high-quality and reliable products.

Current-Limiting Reactors

KPM, LLC has manufactured current-limiting reactors for a long time. Thousands of reactor coils have been made, and huge experience in their manufacture and operation has been gained.

Filter Reactors

They are intended for use in AC networks where due to the specific nature of loads high-frequency disturbances may occur. The reactor, being by its functional principle a filter of higher harmonic oscillations, limits the spread of such disturbances in the electrical network.

Smoothing Reactors

Smoothing reactors are intended to be used in rectified (direct) current circuits of various voltage classes. Such as power circuits of melters, municipal transport overhead contact systems, powerful industrial drives and DC current installations, inserts and lines, etc.

Shunt Reactors

They are used to compensate for reactive power.

Neutral Grounding Reactors

Single-phase reactors designed to be installed between neutral and ground.

Damping reactors

Damping reactors are intended for series connection between power network and bank of capacitors and ensure the following:

  • Current surge limiting during switching of banks of capacitors;
  • Control of overcurrents that might occur during transient-state conditions in the bank of capacitors’ circuit.
Starting Reactors
KPM, LLC manufactures starting reactors for electrical machines of various rating power.
