As part of our turnkey solution for HV/EHV substation automation systems, we executed the detailed internal wiring and termination of control and protection panels. The work included precision routing, labeling, and grounding of low voltage signal and control cables critical to the operation of high-voltage switchgear and protection systems.

Scope Highlights:

• Installation of low-voltage DC wiring (typically 110V/220V DC) for circuit breaker controls, protection relay I/Os, trip/close circuits, and SCADA interfacing.

• Use of ring-lug terminals on brass studs for robust and vibration-resistant connections.

• Clear ferrule labeling for easy identification, troubleshooting, and future maintenance.

• Neatly bundled cable routing with secure cable ties to maintain separation, reduce EMI, and uphold international wiring standards.

• Proper earthing/grounding of terminal strips to ensure operator safety and system reliability.

This meticulous terminal wiring ensures safe, accurate, and reliable communication between the control room and high-voltage equipment in the substation, forming the backbone of efficient and fail-safe grid operations.
