Geometry Inputs

This tool produces indicative geometry records only and must not be used for trench design, duct sizing, burial depth specification, electrical design or any construction document without independent verification by a competent engineer with responsibility for the project.
No electrical calculation is performed.
No thermal rating is performed.
No compliance verdict is produced.
No burial depth design advice is produced.
The user must verify safety, installation depth, protection, rating and utility compliance with a competent person in accordance with local law, site conditions and the relevant power utility or infrastructure owner requirements.
Geometry only. Ready for capture.

Route Identity

Installation Basis

Indicative cover or depth input only. Verify with competent person and utility standard.

Cable OD Lookup

Select voltage and CSA to auto-populate OD and bend factor. All values are for fixed installation only. Flexible applications, very tight bend radii, cleats and terminations must be verified with the cable manufacturer. ★ = anchored on confirmed datasheets. Others from catalogue model. Indicative only.

Formation

OD entered manually.
Spacing inputs are active.

Standing assumptions
  • Within group cable spacing is assumed touching unless separately modelled.
  • Mixed service visual uses one worst case OD for all shown services and is schematic only.
  • Bend visual shows a single cable body sweep only and does not model full multi cable sweep, trench profile, duct entry, pull path or installation forces.
  • Burial depth is recorded as an indicative input only and is not design advice.
  • 4-core and 5-core multicore formations are drawn as a single cable OD. Within-cable core arrangement is not modelled.
Indicative burial depth guidance only
Use this for early geometry capture only, not final design advice.
  • Primary source for LV to 132kV burial depth guidance in this tool is UKPN ECS 02 0019 Installation of Underground Cables LV to 132kV v14.2.
  • For this tool, burial depth should be read as depth to the top of duct or cable as applicable and then verified for the actual installation basis.
  • BS 7671 and ERA 69 30 give thermal rating reference depths, not utility minimum cover requirements. See the official IET BS 7671 page.
  • Street authority and underground apparatus context should be checked at the official GOV.UK underground apparatus code page.
  • Street Works UK should be used as coordination context only, not as the source of the burial depth figures in this tool. See the official Street Works UK publications page.
  • DC minimum burial depth in this tool is a project default assumption only and has no normative source embedded in this release.
The user must verify safety, cover, backfill, duct arrangement, rating, separation, highway loading and protection with a competent person in accordance with the appropriate local regulation and the relevant power utility, infrastructure owner, highway authority or site designer requirements before use.

Worst Case Formation Cross Section

Cable group box only. Envelope width = the horizontal size of the cable group shown. Envelope depth = the vertical size of the cable group shown.

LV AC 33kV AC 132kV AC DC

Indicative Trench Cross Section

Indicative trench size only. Trench width shown = worst case formation envelope width only. Trench depth shown = burial depth input to the top of duct or cable, plus cable formation depth. No bedding, side clearance, cover boards, duct OD, shoring or civil design is modelled.

Single Cable Bend Sweep

Single cable body sweep only. Not multi cable sweep, trench profile, duct entry or civil detail.
