Coexistence between coaxials and power cables
Coexistence of coaxials with power cables Often the installers ask us if a coaxial cable can be placed in the same conduit with power cables (eg nominal electrical voltage 220 or 380 Vac). It has been recently issued by the CEI (Italian Organization for Standardization) the CEI-UNEL 36762 Standard which clarifies this matter.
This Technical Standard specifies the minimum requirements and the tests to be performed on a signal cable so that it can be placed in the same conduit containing power cables.
CAVEL recently submitted all the cables shown in the catalog to this Standard and can now ensure that all products are electrically safe and suitable for use in the same conduit containing power cables. To ensure this the sheath will be marked with the label "CEI-UNEL 36762 C-4 (U0=400V)". Anyway the installer should evaluate if electromagnetic intereference between cables is possible.
