Since 1946 ICAR is a leading manufacturer of electrical capacitors and medium voltage power factor correction
In its 6 plants, located in Europe, ICAR controls all production phases in order to obtain high quality and reliability.
For seventy years
ICAR is one of the leading manufacturers of electrical capacitors and systems in low and medium voltage. Established in 1946, it bases its reputation on 70 years of experience in research, design, development and production of high-performance capacitors, an area where we still maintain an undisputed leadership.
Always at the forefront
First company in the world, ICAR started developing capacitors in metallized polypropylene at the beginning of the 60s. Furthermore, from the beginning we also realized the importance of developing our own metallization systems in order to control the production process from the polypropylene film right to the completed capacitor and systems.
In Italy and in the world
The 6 plants located throughout Europe, which are strongly integrated at a vertical level, allow us (something which is rather rare throughout the world) to directly control the entire production process of polypropylene capacitors: from raw material to finished product.
ICAR offers a full range of capacitors and systems for power factor correction, motors and lighting capacitors, DC and AC capacitors for power electronics applications, voltage stabilizers and active filters. We produce metallized polypropylene capacitors with high gradient and we are among the few manufacturers in the world able to offer capacitors made with the robust technology "paper and oil." We have also consolidated know-how in energy storage and rapid discharge capacitors. We produce in our plants Power factor Correction banks and systems in LV and MV.
RESEARCH AND DEVELOPMENT
ICAR is a leader in designing and manufacturing metallised polypropylene film and metallised paper capacitors for electrical use.
ICAR’s R&D department is endowed with comprehensive product knowledge concerning the dielectric material employed, the metallization, the electrical, thermal and mechanical design thanks to a full vertical integration of all capacitor production stages.
Our technicians can also tune the intermediate processing stages the end product must undergo to reach the level of performance, quality and reliability required by our customers.
ICAR’s R&D department adds outstanding skills when it comes to testing the outcome of design, development and production stages.
As a matter of fact, ICAR can fully develop exclusive capacitor automated testing equipment, compliant with current regulations and/or with specific “custom” tests agreed with the customers.
Also LV power factor correction systems and LV voltage stabilisers are designed and developed by in-house specialised technical teams.
ICAR testing laboratories are able to test products according to the main products standard and /or customer specifications.
The laboratories are located in production plants in order to have an immediate feedback on the production and technical expertise specialized by type of production.
The indoor testing laboratories are arranged over more than 1000 sqm. Monza premises host a facility exceeding 600 sq m of such surface.
In detail, the testing laboratory at Monza site is IMQ certified according to EN ISO IEC 17025 standard, 2005 edition.
Tests are performed according to main product standards:
• EN60871 (HV static power factor correction capacitors)
• EN60252 (Motor run capacitors)
• EN60831 ((LV static self-healing power factor correction capacitors)
• EN61048 -EN61049 (capacitors for fluorescent lighting and similar applications)
• EN61071 (Capacitors for power electronics)
• EN61881 (Rolling stock equipment – capacitors for power electronics)
Performed tests include:
• AC 50Hz voltage tests up to 350kV;
• DC voltage tests up to 250kV;
• AC / DC endurance tests with test temperature from -50°C to 110 °C;
• Short-circuit tests;
• Measurement of inductance and internal series resistance;
• Capacitance and tan δ measurement with frequencies up to 100kHz;
• Tests with predefined impulsive currents;
• Thermal tests with traditional thermal recording and/or thermal imaging recording;
impulse tests: 3/15kV and up to 250kV;
• High frequency tests up to 100kHz;
• Thermal cycles from -50°C to +110°C with humidity up to 95%.
