Overhead Line Design Case Studies

33KV Terminal Support Studies

Energyline has worked with WPD on the 11kV and 33kV distribution network that it operates. As part of an ongoing programme of works, a feasibility study was undertaken to assess a reconfiguration and potential reutilisation of an existing, aged, 33kV lattice steel terminal support, and to assess the pros and cons of replacement with an equivalent 33kV wood pole support.

Skye Reinforcement

Scottish & Southern Electricity Networks (SSEN) were assessing the existing 132kV Quoich to Broadford (QB) overhead line for reutilisation, as part of the larger Skye Reinforcement Project. Energyline were engaged to undertake pertinent studies and surveys to inform the assessment of existing lattice steel towers.
