2021 The 125th year of Izolyator

The history of the high-voltage bushing technology in Russia is inextricably linked with the Izolyator plant. The plant was founded on 6 June 1896 on the outskirts of Moscow in the village of Vsekhsvyatskoe.

Today, Izolyator is a world leader in the development and production of high-voltage bushings in the 12 to 1200 kV voltage range.

The company consists of Izolyator production complex with an area of over 24 thousand sq. m., Izolyator-AKS 126–550 kV cable accessories plant, own R&D center, SVN-Service center, high-voltage electrical equipment test center and the Massa Izolyator Mehru Pvt. Ltd. a Russian-Indian Joint Venture set up for the production of high-voltage bushings with modern RIP-insulation on the territory of India.

The historical annals of the enterprise include the names of more than 100 labor dynasties, many of which work at the plant to this day.

‘Centuries-old traditions — state-of-the-art technologies’ — these words have become the motto for those who work at the enterprise, which is rightfully considered the world leader in the development and production of high-voltage bushings.

Congratulations to Izolyator Company

Vasily Osmakov

First Deputy Minister of Industry and Trade of the Russian Federation

I would like to congratulate you on the big date — the 125th anniversary of the enterprise.

Founded in 1896, the Izolyator plant began to produce products that are truly important for the energy industry and engage in providing the country's population with the necessary electricity. At the beginning of Great Patriotic War, many of the plant's employees were forced to go to the front, the company had to be moved and new specialists were recruited to resume production. Even under such circumstances, the plant was able not only to return to the previous level of production capacity, but also to increase the volume of supplied products, which was especially valuable for the evacuated industry.

Today, Izolyator has in its arsenal technological products that meet all international quality standards, which are in demand both at domestic and foreign facilities of the power complex, which confirms Izolyator's reputation as a reliable manufacturer.

Keeping loyalty to traditions, Izolyator plant conducts active research and development activities and annually presents new and unique solutions and projects in the field of high-voltage bushings. Such significant achievements include the opening of a joint Russian-Indian production in 2018.

Special attention should be paid to the employees of the company, who, over the years of their work, have confirmed their professionalism and commitment. I have no doubt that their experience will play a significant role in the effective implementation of future projects and the achievement of the desired results.

With all my heart I wish you good health and professional success!


Evgeny Grabchak

Deputy Minister of Energy of Russian Federation

Congratulations to the Izolyator team on an anniversary occasion — the 125th anniversary of the founding of the enterprise!

Throughout its history, Izolyator plant has been one of the backbone enterprises that predetermine the technical level and development prospects of the country's electric power industry. So, in the 20s of the last century, the plant was listed as one of the core enterprises for the implementation of the State plan for the electrification of Russia. During the Great Patriotic War, the plant delivered its products to power plants in the eastern regions of the country, as well as reconstructed power systems in the liberated territories. In the post-war years, the country's electric power industry developed, voltage classes grew higher, and with them the plant grew and developed.

Today, like past decades, Izolyator maintains and strengthens its leading positions in the development and production of advanced high-voltage insulating equipment both in Russia and on the global electrical market.

The combination of centuries of experience and an innovative approach, continuous improvement and implementation of the latest production technologies, highly qualified personnel and effective management allow the company today to make a significant contribution to the creation of the image of the energy sector not only of the present, but also of the future.

I wish the entire staff of Izolyator plant further successful development, new large-scale projects and professional achievements, good health and happiness!

Kirill Lunin


We sincerely congratulate the Izolyator team on a remarkable anniversary - the 125th anniversary of the founding of the enterprise!

Anniversary days are a special time for all of you, the plant’s employees. On such days, more than a century-old path of the company can be clearly traced and one can appreciate the conquered peaks and reflect on the future.

The plant began its history with the production of low-voltage porcelain insulators for telegraph, telephone lines and for the needs of the railway.

The formation of the company took place during the years of intensive development of the domestic power sector. In order to implement the GOELRO plan, the plant mastered the production of suspension insulators and significantly increased their output.

The plant played an important role during wartime and during the period of power sector recovery.

Maintaining its course of continuous development, now Izolyator is a backbone enterprise, manufactures products using the most promising world technologies, while constantly increasing production volumes.

The company's achievements are known not only on the Russian, but also on the international level. The plant is the only one in Russia capable of developing, producing and testing ultra-high voltage bushings.

Of course, such results can only be achieved with the help of a responsible, hardworking team, competent leadership and a focus on continuous improvement.

May the company be accompanied by good luck for many years. We wish you, dear colleagues, to continue the path of professional achievements, and warmth and prosperity to your families!


Victor Larioshkin

General Director of Bashkir Generation Company (BGC)

I sincerely congratulate you, the entire staff and veterans of Izolyator on an important date - the 125th anniversary of the plant!

The importance of your company can hardly be overestimated for the power industry throughout the country. Founded back in 1896, Izolyator quickly achieved success in the production of porcelain insulators, and during the years of the GOELRO plan, it successfully coped with the most difficult tasks, increasing production volumes and mastering the output of modern products.

A separate, special milestone in the history of the company is the activity of the plant in the hardest years of the Great Patriotic War. Veterans of the enterprise truly became one of those who forged the

Great Victory in the rear and contributed to the defeat of the Nazi regime. This arouses great reverence and endless respect.

We can say with confidence that thanks to the accumulated experience, competent management, unique technologies and a close-knit team, Izolyator is a recognized leader in Russia in the development, production and service support of modern high-voltage bushings of all voltage classes.

The products of your plant in Bashkortostan are widely known. Long-term trouble-free operation of high-voltage bushings of transformers and wall bushings of Izolyator in switchgears of power plants of the Bashkir generating company has become synonymous to high reliability and quality. I am confident that our close and productive cooperation for the benefit of the energy sector of the region and its inhabitants will continue.

I wish Izolyator new horizons of development - every year to build up its power and keep its course!

Good health, optimism and confidence in the future to you, your colleagues and veterans of the enterprise! Good luck in your work, well-being and prosperity!
