The Utility Design data model contains the following two networks:
- Structural network: Segments, ducts, poles, vaults, manholes, handholes, and other structural features build the structural network.
- Electrical network: Conductors and devices such as transformers, breakers, and switches build the electrical network. Features in the electrical network are conductive.
The two networks are related. Segments contain ducts which in turn contain conductors. (Ducts can also contain other ducts.)
