Overview
EN 50525-2-83:2011 is a European Standard published by CLC (CENELEC) that specifies requirements for low voltage multicore electric cables with crosslinked silicone rubber insulation. These cables are designed for rated voltages up to and including 450/750 V (U0/U). Specifically, the standard addresses multicore cables with heat-resistant crosslinked silicone rubber insulation and sheathing intended for use in high temperature environments.
The standard covers cables both with and without an overall textile braid and with or without a strain-bearing element. These cables are suitable for fixed installations with mechanical protection as well as flexible use under low mechanical stress. A key feature of cables conforming to this standard is their capability to withstand a maximum conductor operating temperature of 180 °C.
EN 50525-2-83:2011 should be read alongside EN 50525-1, which specifies the general requirements for low voltage energy cables.
Key Topics
Cable Construction
- Conductors must be Class 5 stranded according to EN 60228.
- Insulation is made from Type EI 2 crosslinked elastomeric silicone rubber (EN 50363-1).
- Sheath uses Type EM 9 crosslinked elastomeric silicone rubber (EN 50363-2-1).
- Possible inclusion of a textile braid for extra mechanical protection.
- Strain-bearing elements made of non-metallic materials may be included, designed to reduce strain on conductors.
Cable Types Covered
- H05SS-F & H05SST-F: Basic multicore heat-resistant cables with or without braid.
- H05SSD3-K & H05SSD3T-K: Multicore cables with strain-bearing element, with or without braid.
Operating Conditions
- Rated voltage: U0/U 300/500 V.
- Max conductor temperature: 180 °C, suitable for high-temperature zones.
- Application in fixed installations with mechanical protection or flexible usage under low mechanical stress.
Testing & Compliance
- Electrical, mechanical, and material tests per annexes to ensure quality and performance.
- Ageing tests at 200 °C to simulate long-term heat exposure.
- Fire resistance tests for flame propagation.
- Compatibility tests on insulation and sheath materials.
- Dimensional checks for insulation thickness, sheath thickness, and overall cable diameter.
Marking & Identification
- Cables marked with CENELEC codes like H05SS-F, H05SST-F, H05SSD3-K, and H05SSD3T-K.
- Marking aligns with EN 50525-1 requirements for traceability and identification.
Applications
EN 50525-2-83 cables are designed for demanding electrical installations where high temperature resistance and mechanical reliability are critical. Common applications include:
- Industrial settings, such as zones with high ambient temperatures or heat sources.
- Fixed installations where cables require mechanical protection (e.g., conduits in factories, HVAC systems).
- Flexible connections under low mechanical stress, suitable for equipment that requires frequent movement but little strain.
- Use in environments requiring compliance with fire safety standards due to flame retardant properties.
- Situations demanding strain relief via strain-bearing elements to protect conductors in flexible cables.
By meeting stringent European and IEC standards, these cables ensure safety, durability, and performance in both residential and commercial electrical systems.
