The design office within the factory structure, which designs terminals and fittings, allows us to independently solve new product development tasks and introduce them to the market in a short period of time. The work of the factory's design team was highly appreciated not only by specialists from Lithuania, but also from other countries: Norway, Finland, Sweden, Denmark, the Netherlands, Poland, Latvia, Estonia, Malaysia, India, Indonesia, Kazakhstan, Algeria, Vietnam, Serbia, Spain, Portugal, Greece, Great Britain, Bolivia, Turkey, etc. Among our completed projects are: Finland 110 kV overhead line project, Czech Republic 35-110 kV overhead line project, Congo DRC 132- 220 kV overhead line and substation projects (SNEL, Niamy), Bulgaria 110 kV overhead line projects, Algeria substation 110 kV project, Nigeria 132 kV line, Lithuania-Poland border 400 kV line and others, some of the projects you can see on our website.

In recent years, the company has been investing in the production and patenting of new products. AIZ can offer exclusive products in the field of silicone pin insulation and support insulation, in the fields of substation terminal design and production. "AIZ" has implemented a quality management system in accordance with the requirements of the ISO 9001 standard, and the ISO 14001 environmental management system standard has also been implemented.

Currently, the plant is actively developing the production of terminals and insulators of all classes and types. The plant's design team is striving to introduce various types of insulating materials such as: porcelain, glass, polymer, composite base. According to the new product development program, the plant currently produces terminals and fittings for polymer support insulators up to 400 kV, rod-shaped linear insulators up to 500 kV (CS type), support-pin insulators for substations (PI type), rod-shaped linear insulators 10 kV and 20 kV (which replace the outdated ŠF-20 insulators), as well as pin-shaped polymer insulators, transitional polymer insulators up to 35 kV and currents up to 4000A.

According to the development plan, by 2027 the plant will start producing input terminals for transformers, terminals for digital fiber-optic current transformers with an accuracy class of 0.02S at voltages up to 220 kV, terminals for digital voltage transformers connected to ASKUE current transformers, polymer insulators for 110 and 400 kV, etc.

The main products of the plant are terminals, screw terminals and connectors, fittings and insulators for high-voltage power lines and substations:

• - intended for insulating and fastening overhead power line wires, lightning protection cables;
• - used in power and substation distribution devices for direct and alternating currents with a frequency of up to 1000 Hz and an ambient temperature from -60°C to +50°C;
• - used for railway electrification;
• - used in areas with different levels of atmospheric pollution;
• - intended for use in cold, humid and tropical climate conditions.

Insulators are manufactured based on the most advanced technologies, new scientific and technological achievements in the field of materials and energy. The factory's products are well known in more than 30 countries of the world. They have passed tests in certification centers, laboratories and national institutes in many countries: Zagreb (Croatia), Budapest (Hungary), "SGS" (Finland), IEN (Poland), etc. The electrotechnical characteristics of the goods, their types and sizes comply with international standards - IEC 60305, IEC 60120, IEC 60383, IEC 60372, IEC 61109, 61238, etc.
