Uo/U - 300/500V
Standard: DIN VDE 0250 part 214
Cu conductors • XLPE insulation • LSF sheaths
Application
The power insulated conductors flame retardant, with low halogen free smoke emission and corrosion at fire
conditions are suitable for use in electrical installations for Uo/U 300/500 V in:
important objects - power stations (nuclear, thermal), transformer substations, metro, airport,
public buildings - hospitals, hotels, theaters, cinemas, public and commercial centers,
places with great concentration of people and material values whose safety in case of fire should be
guaranteed.
The conductors are designed for laying over, in and under plasters in dry and wet premises as well as in
brickwork”s and concrete. They are also suitable for outdoor use.
The conductors should not be laid directly in vibro concrete or rammed concrete and directly under ground.
