HV cable systems
Cable sizing, route and trench design and cable system specification for HV networks and substation interconnections.
The problem this solves
Cable systems are frequently under-engineered relative to their cost and consequence. Incorrect sizing, poor route design or an incomplete specification leads to de-rated circuits, installation clashes and cables that cannot be pulled, jointed or maintained as intended.
Project types we support
- Substation interconnections and circuit replacements
- Generation and demand connection circuits
- Private wire networks and site-wide HV distribution
- Cable diversions and reinforcement schemes
Design, calculation and study work
- Cable sizing calculations, including thermal and installation conditions
- Route selection and constraint assessment
- Trench, duct and joint bay design
- Cable system specification for procurement
Deliverables
- Cable sizing calculations and selection reports
- Cable route drawings and trench profiles
- Duct, joint bay and crossing details
- Cable system specifications and schedules
How this reduces risk
Correct sizing and a buildable route protect the circuit rating the wider design depends on. A complete specification and trench design reduce installation risk, avoid clashes with existing services and prevent the programme delays that follow redesign during construction.
Why appoint Saqib Engineering
Cable design here is not an afterthought to a substation package. Routes, trench profiles and specifications are engineered with the same rigour and checking as the substations they connect.
Common questions
- How do you size HV cables?
- Cable sizing accounts for the circuit rating, thermal and installation conditions, grouping, soil thermal resistivity and route length, so the installed circuit carries its design rating rather than a de-rated one. The result is documented in a selection report for procurement.
- Do you design cable routes and trenches as well as sizing?
- Yes. We design routes, trench and duct profiles, joint bays and crossings, so the circuit can be pulled, jointed and maintained as intended, and clashes with existing services are found on the drawing rather than on site.
