This document introduces the SILFLEX SiHF product launched by Lapp Limited in the Farnell Catalogue. The product is a temperature-resistant and halogen-free silicon multi-core cable that can be used in high ambient temperatures ranging from -50°C to +180°C. The cable is resistant to mineral oil, alcohol, acids, alkalis, salt solutions, and saltwater. After combustion, it forms a SiO2 ash skeleton which retains good insulating properties but loses mechanical stability. The cable's gases are halogen-free and non-corrosive. The cable is designed according to VDE 0250 part 816, with a conductor strand made of tinned copper wires according to IEC 228 and VDE 0295 class 5. The core insulation is made of a silicone-based compound 2GI1 according to VDE 0207 part 20, and identification of up to 5 cores is in accordance with VDE 0293, with more than 5 cores being black with white numbers. The outer sheath is made of a silicone-based compound according to VDE 0207 part 21 (2GM1), and the outer sheath color is red RAL 3000. The electrical properties include a nominal voltage of 300/500 V and a test voltage of 2000 V AC at 20°C. The mechanical and thermal properties include a minimum bending radius of 15 times the cable diameter for flexing use. The cable is flame retardant according to IEC 60 332.1 resp. VDE 0482 part 265-2-1, and halogen-free according to IEC 754-1. It has been tested according to VDE 0472 and IEC 811-x.x that is VDE 0473, and it complies with the EC directive ECD 73/23/EEC (low voltage directive).
The SiHF silicone multi‑core cable from Lapp is designed for use in high ambient temperature environments with adequate ventilation and low mechanical stress. It offers resistance to mineral oil, alcohol, acids, alkalis, salt solution and salt water.
Key properties include a nominal voltage of 300/500 V, test voltage of 2000 V AC, a minimum bending radius of 15 × cable diameter, and compliance with IEC 60332‑1 flame‑retardant and IEC 754‑1 halogen‑free standards. The cable features tinned copper conductors, silicone‑based core insulation (2GI1), and a red outer sheath (RAL 3000).
