SiFCuSi 300/500 V Screened Silicone Cable
SiFCuSi is a 300/500 V screened silicone cable with tinned copper braid for high-temperature, low-mechanical-load connections.
SiFCuSi screened silicone cable for high-temperature connections
TEBAOFLEX SiFCuSi is a 300/500 V screened silicone cable for dry, damp and wet locations, as well as open-air installations with low mechanical loads at elevated ambient temperatures. The supplied SiFCuSi construction combines fine-stranded tinned copper conductors, silicone insulation, a PETP foil wrap, tinned copper braid screen and a reddish-brown silicone outer sheath. The copper braid is stated to optimise protection against high-frequency external interference.
For final selection, confirm the equipment connection, route, screen termination, mechanical protection, core count, conductor size and applicable installation requirements. The supplied data provides operation from −60°C to +180°C, while the temperature information also states +250°C for short-circuit use for five seconds.
- Voltage: 300/500 V; test voltage 2,000 V.
- Conductor: IEC 60228 Class 5 fine-stranded tinned copper.
- Screen: tinned copper braid.
- Bending radius: 10 × DA when laying; 5 × DA for fixed installation.
