SRPS EN 50483 Standards for Testing Accessories for Low-Voltage Aerial Bundled Cables
MAREL Laboratory performs testing in accordance with the SRPS EN 50483 series of standards, which includes the following parts:
• SRPS EN 50483-1:2010 – Test requirements for accessories for low-voltage aerial bundled cables — Part 1: Generalities
• SRPS EN 50483-2:2010 – Tension and suspension clamps for self-supporting systems
• SRPS EN 50483-3:2010 – Tension and suspension clamps for neutral messenger systems
• SRPS EN 50483-4:2010 – Connectors for low-voltage aerial bundled cables
• SRPS EN 50483-5:2010 – Electrical ageing test
• SRPS EN 50483-6:2010 – Environmental testing
These tests enable verification of all elements of low-voltage systems, from clamps to connectors, ensuring that the tested equipment complies with all technical requirements defined by these standards.
SRPS EN IEC 61238 Standards for Testing Compression and Mechanical Connectors for Power Cables
MAREL Laboratory performs testing in accordance with the SRPS EN 61238 series of standards, which includes the following parts:
• SRPS EN IEC 61238-1-1:2020 – Compression and mechanical connectors for power cables – Part 1-1: Test methods and requirements for compression and mechanical connectors for power cables for rated voltages up to 1 kV (Um = 1.2 kV), tested on non-insulated conductors
• SRPS EN IEC 61238-1-2:2020 – Compression and mechanical connectors for power cables – Part 1-2: Test methods and requirements for insulation piercing connectors for power cables for rated voltages up to 1 kV (Um = 1.2 kV), tested on insulated conductors
• SRPS EN IEC 61238-1-3:2019 – Compression and mechanical connectors for power cables – Part 1-3: Test methods and requirements for compression and mechanical connectors for power cables for rated voltages above 1 kV (Um = 1.2 kV) up to 36 kV (Um = 42 kV), tested on non-insulated conductors
Testing in accordance with these standards enables confirmation of the quality of compression and mechanical connectors, as well as their long-term reliability
SRPS EN 61284:2009 – Overhead Line Fittings for Voltages Above 45 kV
The SRPS EN 61284:2009 standard applies to overhead line fittings for rated voltages above 45 kV. Although it is primarily used for testing components in high-voltage systems, this standard can also be applied to fittings for lower voltages, as well as similar fittings used in transformer substations.
For overhead line connections, the accuracy, reliability, and safety of joints are of essential importance. Testing in accordance with this standard enables verification that fittings meet the technical and mechanical requirements for safe operation and long-term resistance to external influences.
MAREL performs testing according to SRPS EN 61284:2009, guaranteeing that fittings meet all technical parameters required for high-voltage applications, thereby ensuring reliable system operation.
SRPS EN ISO 1461:2022 – Hot Dip Galvanized Coatings on Iron and Steel Products
For all components exposed to external conditions, the EN 1461 standard specifies the general properties and test methods for hot dip galvanized coatings applied to iron and steel products (including certain cast products) by immersion in molten zinc (containing no more than 2% of other metals).
