Overhead Line Design

As well as conducting overhead line surveys, Line Design Technology Limited staff are also skilled in the production of overhead line designs.

This type of detailed design is based on the data collected in the initial survey and is necessary when obtaining consent for a project to move ahead.

Additionally, contractors will refer to the overhead line design when the time comes to purchase the requisite materials, and then throughout the actual construction of the power lines.

LDT design engineers use computer-aided design software to create detailed schematics that include the foundation requirements, the sag and swing of conductors, and the forces that will be imposed on the power lines by the surrounding environment.

Below are details of some of the projects we've worked on over the years

Total Station

Ellesmere Port - New Connection

Ellesmere Port Design

As part of an ongoing commitment to modernising the electricity network, Scottish Power engaged our services to produce detailed design drawings of a proposed reconfiguration of the downleads on the terminal tower at Ellesmere Port.

A survey of the tower was conducted to locate all the attachment points and post insulator positions.

This enabled us to check wire clearance on the proposed downleads, to ensure the safety distances could be achieved.

Detailed three-dimensional drawings were produced showing the new arrangements as well as the materials needed by the appointed contractor.

The project was successfully completed in 2014.

Legacy to Oswestry 132kV Trident Line

Lostock Construction Works

LDT were awarded the contract to survey and design the Legacy to Oswestry 132kV Trident line.

The project was approximately 20 km in length.

The route was mainly open farmland with a crossing of the River Dee as well as the A483 trunk road.

The findings of the initial routing studies were used to shape the final route and the entire circuit was surveyed using total station and RTK GNSS.

Line profiles and detailed route plans were produced as well as material schedules and foundation drawings.

This formed part of the contractor work pack that was issued out to facilitate the construction of the proposed line.

A public enquiry was held as part of the planning of the line and LDT were engaged to act as advises to the expert witnesses produced by Scottish Power.

The planning application was successful, and the line was constructed in 2014.
