HV Cable Systems
Underground Cable Design
High-voltage cable systems sized, routed, and protected to IEC standards.
01 · Overview
Our underground cable designs cover the full scope from conductor selection through trench layout and civil interface. We produce thermal rating studies, protection coordination reports, and complete installation packages for systems up to 380kV.
02 · Deliverables
- Cable sizing and conductor selection
- IEC 60287 thermal rating calculations
- Route planning and plan/section drawings
- Joint bay and termination layouts
- Bonding and earthing design
- Cable protection and fault level studies
- Civil trench and duct coordination
- Testing and commissioning specifications
