Previously, you had high-voltage cables in one trench and data cables in another. Today, substations are "smart." They are run by digital relays and fiber optics. The "plot twist" in this revision is the intricate detailing of how to lay these cables together.

Any power installation with AC voltage >1 kV (e.g., 33 kV solar collector substation, 132 kV wind park substation) must conform to IEC 61936-1. Previously, you had high-voltage cables in one trench

Overall, the IEC 61936-1:2021 standard is a valuable resource for ensuring the safety and reliability of power installations. Its comprehensive guidelines and recommendations can help electrical engineers, designers, operators, and maintainers design, construct, and maintain power installations that meet the highest safety and performance standards.
