Cabling

(OP)
I want to do the cabling design in a 230/63kV substation.

Is it necessary to segregate the measuring cables (CT, VT) from control cables along the cable route.
The measuring cables are shielded wire armoured. and the control cables are wire armoured.

Is there explicit rule in this respect?

RE: Cabling

See:

"IEEE guide for the design and installation of cable systems in substations", ANSI/IEEE Std 525-1987

Abstract:
This standard has been developed as a guide for the design, installation, and protection of wire and cable systems in substations with the objective of minimizing failures and their consequences. The purpose of this guide is to give direction to the substation engineer in established practices for the application and installation of metallic cables in electric power transmission and distribution substations. This guide emphasises reliable electrical service during the design life of the substation.
