Dear colleagues, welcome to our website!

Limited Liability Company BOLID was established in 1991 on the basis of the laboratory of composite resistance materials at the Siberian Research Institute of Power Engineering. Its employees solve a broad scope of tasks ranging from experimental investigations in 6-35 kV networks, mathematical simulation of transient processes, and failure investigations to the development and commercial production of composite conductive and dielectric materials, including multifunctional nanotechnologies, and development of power engineering products and domestic appliances made of composite materials.


At present, 77 people work in BOLID, 35 of them have higher education. Industrial premises occupy 1500 m2. Production is done with total technical control. All products are manufactured in accordance with approved technical specifications. They comply with national standards.

Main direction of the company’s activity is manufacturing of high-voltage neutral grounding resistors for 3-35 kV networks. By now, LLC BOLID has manufactured and put into operation about 1000 resistors for the rated voltage 3-35 kV. Key customers of BOLID are Gazprom JSC, LUKOIL, Interregional Distribution Grid Company (IDGC) of Volga JSC, IDGC of Urals JSC, IDGC of Siberia JSC, Irkutskenergo JSC, and others.

Neutral grounding resistors RZ and RZ1 comply with the international standard IEEE Std 32-1972 'IEEE Standard Requirements, Terminology, and Test Procedure for Neutral Grounding Devices' (Certificate of Conformity and TÜV Bauart Mark issued by TÜV Rheinland InterCert Kft).

Intellectual potential of BOLID personnel in conjunction with experience and skills of complex scientific and technological research are the main company’s resources. High-qualified personnel provided with modern equipment for experimental investigations are ready to help with qualitative implementation of your ideas.

BOLID regularly presents papers about its investigations and products at various conferences in St. Petersburg, Moscow, Norilsk, Ukraine, Estonia, and others. Since 2000, BOLID in collaboration with the Department of high-voltage engineering and electrophysics of Novosibirsk State Technical University and Fenix-88 CJSC have held All-Russian scientific and technical conference “Overvoltage limitation and neutral grounding in 6-35 kV networks”. On September 2008, the 5th All-Russian Scientific Technical Conference was held, where over 60 specialists from power supply systems, oil, gas and chemical plants, mining and metallurgy industry participated.

BOLID plans to introduce new modern technologies, develop and manufacture new products, certify its production in accordance with European and American standards that will allow the company to enter the international market.
