Sonar LLC

Dear Colleagues,

Sonar LLC was founded in 1997 with the aim of developing the market for goods and services in the regions of Ukraine. The company’s main business activity is the production and sale of electrical insulation materials, the demand for which has shown a steady upward trend in recent years.

Sonar LLC supplies industrial facilities with specialized electrical insulation materials and, upon customer request, makes modifications to design documentation using more advanced electrical insulation materials.

For many years, the company has actively cooperated with numerous enterprises in the nuclear power, metallurgical, mining and processing, electrical engineering, and transportation industries, serving more than 2,000 enterprises and industrial plants overall.

To ensure prompt supply of materials to enterprises, representative offices of Sonar LLC were opened in Dnipro and Kharkiv.

Today, according to the technical specifications developed by Sonar LLC, we manufacture 33 types of electrical insulation materials, including:

• impregnated and non-impregnated mica tapes for turn-to-turn and ground-wall insulation of high-voltage electrical machines, generators, and traction motors using Resin Rich and VPI technologies;
• non-impregnated high-temperature tapes for fire-resistant cables, approved and included in the technical specifications of UkrNDIKP, Berdyansk, for the nuclear industry;
• electrical engineering mastic;
• commutator gaskets for electric motors, generators, and starters of various capacities;
• combined electrical insulation materials: Syntoflex, Eliflex, Isoflex, Imidoflex, and Alumoflex;

The company is equipped with modern machinery (presses for stamping commutator gaskets, cutting machines, tape-weaving equipment, impregnation, varnishing, and grinding units), other technological equipment, and a laboratory for testing electrical insulation materials during production and for conducting periodic tests.

The materials manufactured by Sonar LLC have successfully passed endurance testing at the certified laboratory of UkrNDIVE.

Thanks to cooperation with leading manufacturers of electrical insulation materials, we provide comprehensive supply solutions for electrical insulation products.
