Objectives	To demonstrate that the physical T-pylon structures are suitable for utilising on the GB transmission system. The output will be a certified test report, which will feed in to the specification being developed outside of this R&D scheme. To find a composite insulator solution that meets National Grid requirements based on the geometry required by the t-pylon, and can be offered by suppliers for use on the 400kV Transmission system. Secondly, to ensure that there are multiple suppliers that are able to offer this solution for implementation on the National Grid 400kV Transmission system. Validation of the design loads on two T-pylon structures (one suspension and one tension) and a flying angle T-pylon insulator assembly which will validate all the structural design methodology for the whole family of 6 T-pylon designs. This will be in the form of an independent report, by a certified body. Minimum of one supplier proven to be able to deliver type registered composite insulator solutions for the T-pylon. This will also be in the form of a report.
Abstract	Visual amenity of new Electricity Transmission assets, particularly overhead line routes, is becoming increasingly important to stakeholders. National Grid began developing the T-pylon as a more visually amenable alternative to traditional 400kV electricity transmission towers to aid the mitigation of visual impact of any new route. There are further aspects of demonstration required to ensure that the T-pylon structure and insulator solution meet all 400kV safety, environmental and operational performance requirements before they can be deployed. Demonstration Two T-pylon structures (one suspension and one tension, from 1 supplier) and a flying angle T-pylon insulator assembly will be procured (from a different supplier) and subsequently tested to maximum design loads to validate the design solutions simulated behaviour. Electrical and mechanical verification testing and wind testing of the novel composite insulator solutions of three suppliers (therefore 3 insulator solutions) to prove the design solutions meet National Grid requirements in support of type registration.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
