Lavspenning/Kabler/Signalkabel - FEBI XXx1,5 mm² 750V
1 SCOPE
1.1 Purpose
The purpose of the technical specification is to provide guidance for the production, test procedures and delivery of products according to stated requirements. The technical specification contains technical and functional requirements to be fulfilled.
The cables shall provide capability to transfer power and/or data signals to external safety facilities. The cables shall be free of halogens and self-extinguishing. The cables shall withstand relevant loads that may be present in normal operation of safety facilities for railways.
F (1. letter) = massive insulation of PE / PP with filling compound (Vaseline)
E (2. letter) = sheath of PE / PP
B (3. letter) = armouring (2 steel tapes)
I (4. letter) = outer sheath of halogen-free polymer (self-extinguishing)
The cables will be a part of the safety facilities of the railway infrastructure.
1.2 History
Previous editions of the technical specification did not deal with filling compounds like Vaseline. (Technical designation: EESI or EEBI, as specified in document S.800175, v.000.)
The cables in this specification have got the designation starting with FEBI – and all variants should include Vaseline and steel tapes for protection and EMC.
