Innovative CAntilever for Greener Electrification at the Global Centre of Rail Excellence (ICAGE GCRE)

目前，英国42%的铁路网络是电气化的，其中4，238公里使用架空线路电气化（OLE）基础设施（公路和铁路办公室2018/19）。根据网络铁路TDNS的结论，电气化是一个积极的商业案例，但在英国，滚动计划的成本约为每单轨公里150万英镑，而德国通常为每stk 100万英镑。RIA电气化成本挑战-2019年3月强调，由于原材料，结构安装和基础，OLE对总成本的贡献可能高达45%。目前，正在开发复合电气化悬臂，但这些利用传统的电气化悬臂。一个典型的电气化悬臂，包括金属支架，电绝缘体和金属安排，以支持轨道上方的电线。当与复合材料杠杆一起使用时，这种布置受到限制。电绝缘体价格昂贵，交货期很长。由于有金属支架，整个复合悬臂需要电粘接（成本），重量还是一样的作为回应，F+F将开发一种破坏性的首个复合悬臂，以解决以下问题：1.重量--更轻的悬臂意味着建筑中使用的悬臂和基础更小（降低成本和建造时间）2.它将消除对电绝缘体的需要（降低成本、安装时间和嵌入碳）开发复合悬臂将消除这些问题并允许创建更容易安装的整个系统，降低资本成本和隐含碳。该项目代表了下一步将开发和演示复合材料杠杆。设计和制造过程将在威尔士GCRE的支持下开发，以证明铁路环境中的创新设计，以克服实际集成，性能，弹性和未来要求（包括认证）的运营障碍。

Currently 42% of the UK's routed rail network is electrified, with 4,238km using Overhead Line Electrification (OLE) infrastructure (Office of Road and Rail 2018/19). According to Network Rail TDNS conclusions there is a positive business case for electrification however the cost of rolling programmes in the UK is around £1.5 million per single track kilometre (stk) against for instance, Germany where it is typically £1m per stk. The RIA Electrification Cost Challenge -- March 2019 highlighted that the contribution of the OLE to the total cost can be as high as 45% due to the raw material, the installation of the structure and the foundation.For rail electrification to be sustainable, there is a need to lower capital costs and embodied carbon. Currently, composite electrification cantilever s are being developed, but these utilise conventional electrification cantilevers. A typical electrification cantilever, consist of metal brackets, electrical insulators and metal arrangement to support the wires above the track. This arrangement is limited when used with composite cantilevers. Electrical insulators are expensive and have very long lead-times. Due to metal brackets, the entire composite cantilever requires electrical bonding (cost) and is still the same weight (bigger foundations).In response, F+F will develop a disruptive first-of-a-kind composite cantilever, to tackle head on the issues of:1.Weight -- lighter cantilevers mean smaller cantilever s and foundations are used in construction(lowering costs and time to build)2.It would remove the need to have electrical insulators (reduction in cost, install time and embodied carbon)Developing a composite cantilever would remove these issues and allow the creation of an entire system that is easier to install, lowering capital costs and embodied carbon.This project represents the next step in which composite cantilevers will be developed and demonstrated. The design and manufacturing process will be developed proving the innovative design in the railway environment with the support of GCRE in Wales to overcome the operational barriers to practical integration, performance, resilience and future requirements including certification.
