Maximum Power and Safety on Rails: ITELCOND Surpasses the Strict IEC 61881-2 Railway Standard

Ironclad reliability with certifications from external laboratories for the most demanding environments.

ITELCOND: power and reliability for the railway industry. It is a company specializing in the design and manufacture of high-performance aluminum electrolytic capacitors. Standing out in large formats and inverter applications, it offers robust components that ensure maximum efficiency in railway electrification and traction.

 

Railway sector specifications are becoming increasingly strict, and currently, compliance with the IEC 61881-2 standard is being demanded. Until now, the required standard was IEC 60384-4, which acts as the generic standard for electrolytic capacitors.

The IEC 61881-2 standard is specifically designed for rolling stock equipment and power electronics capacitors (aluminum electrolytic capacitors with non-solid electrolyte). This regulation ensures high reliability and safety for capacitors used in the demanding environment of railway power electronics. To achieve this, it defines specific performance, service life, and testing requirements that go beyond general electronics standards. A critical point of this regulation is fire behavior and flammability, outlined in section 5.12.

At Aldinet, we go a step beyond commitment. We know that in the railway sector, trust is proven with facts, not just labels. That is why ITELCOND has gone beyond standard self-certifications, validating each component in prestigious external laboratories. Because for your integrations, only external certification guarantees maximum reliability on the rails.

 

 

Itelcond's certified regulatory compliance covers critical areas for the railway environment:

• IEC 61881-2 and IEC 60384-4: Compliance with all electrical performance requirements, quality tests, and routine parameters. This includes strict capacitance and leakage current tests, further supported by the generic specification for fixed capacitors with solid and non-solid electrolytes.
• IEC 61373: Certified resistance to vibrations and shocks, ensuring reliability under the mechanical stress typical of rolling stock.
• EN 45545-2 and ISO 4589-2: Compliance with fire safety regulations, including requirements for flame spread, smoke toxicity, and oxygen index (OI), guaranteeing maximum protection in railway applications.

To guarantee this performance independently, external laboratories have subjected Itelcond's capacitors to the following tests:

• EN 17084:2018: Toxicity testing of materials and components for fire protection on railway vehicles.
• EN ISO 5659-2:2017: Determination of optical density (smoke generation) using a single-chamber test.
• EN 45545-2:2020: Requirements for the fire behavior of materials and components.
• ISO 4589-2:2017: Determination of fire behavior by oxygen index (ambient-temperature test).
• EN 61373:2012: Shock and vibration tests for rolling stock equipment.

ITELCOND consolidates its position as a fully trusted primary manufacturer, guaranteeing that its components exceed the safety and durability requirements of the modern railway sector.
