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.
The user must verify safety, protection, rating and utility compliance with a competent person in accordance with local law, site conditions and the relevant infrastructure owner requirements.
Geometry only. Ready for capture.

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.
  • 4 core and 5 core multicore formations are drawn as a single cable OD. Within cable core arrangement is not modelled.
Open cable knowledge basis
This interface is intended to expose geometry assumptions clearly and separate them from catalogue driven product selection.
  • British MV classes retained here are 6.35/11 kV and 19/33 kV.
  • Transmission class retained here is 64/110 kV IEC system.
  • Sector conductors are called out because they affect OD and terminations.
  • Stored ODs and bend data must still be verified before any formal design issue.

Worst Case Formation Cross Section

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

Indicative Trench Cross Section

Indicative trench size only. Trench width shown is worst case formation envelope width only. Trench depth shown is 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.
