Application of S3Z2Z2-K Cables
1) Halogen-free single core cables, sheathed, for junction boxes and inverters, with improved fire performance, increased heat resistance and suitable for direct burial.Intended for use in photovoltaic power supply systems, at nominal voltage rate of 1,8/3kV AC, as interconnection between central inverter and transformer station.
2) Applicable indoor and outdoor in explosive and hazardous areas within industry and agriculture. Also suitable for applications in equipment with protective insulation class ll or as short and ground fault protection. Can also be used as unfused connections in switchgear and distribution boards up to 1000 V (DIN VDE 0100-520 and DIN VDE 0660-500) and in accumulator circuits (DIN 5510 part 5).
Construction: Finely stranded tinned copper Class 5 acc. to IEC 60228
Insulation: Halogen-free Heat resistant Cross-linked rubber compound
Outer sheath:Halogen-free Heat resistant Cross-linked rubber compound, UV-resistant
