RIBE Conductor Fittings for National Grid
PACE Networks is privileged to be awarded multi-year framework contracts with National Grid for the framework for a range of Conductor Fittings with our partner RIBE. A range of Vibration Dampers from the framework has successfully passed a series of tests to NG specification TS 03.04.35. Type Registration of these products and the first orders are expected early in 2018.
Rebosio Polymeric Insulators for National Grid
PACE Networks is privileged to be awarded multi-year framework contracts with National Grid for Rebosio polymeric insulators at 132kV, 275kV and 400kV as our national utility recognises the benefits of polymeric insulators over either porcelain or glass.
TDL Replacement – Oswestry to Legacy
The 132kV Heavy Duty Legacy to Oswestry Trident project was installed by BBUSL in 2015 with equipment supplied by SP Energy Networks. PACE supplied the Tension Insulators, E00897R-5 and the Line and Pilot Post Insulators, E00865A and E01054S to SP Energy Networks. The route modification is part of the 132kV Substation rebuild which is being up scaled to provide security and flexibility to the existing network in and around Oswestry. The insulators were manufactured to be exactly the same size as the trident specification from the eighties, therefore allowing a direct replacement of the existing old insulator technology and also providing huge savings in the reduction of change in other areas.
During 2015, PACE Networks worked with Babcock and SP Energy Networks to trial 132kV Composite Insulators for use on Tower Projects. Other UK DNOs / TNOs have been utilising polymeric technology for several years and SP Energy Networks wanted to this next step to gain the inherent benefits for their network at this voltage. PACE provided the Suspension and Tension Insulators for this project to be installed by Babcock on the HAR Route, running through the Cheshire countryside. Feedback from the installation team highlighted they were extremely easy to install and saved a lot of time compared to Glass insulators. They were easier and safer to handle and more work could be completed when compared to Glass, which in turn saved money on Wayleaves, reduced plant operation activities due to less weight logistics and other time related activities. As a direct result of the HA trial, our suspension and tension 132kV insulators up to 190kN are now fully approved for Tower Projects by SP Energy Networks.
Western Power Distribution – K Lines
PACE Networks are currently providing full strings to Wester Power Distribution to replace their existing aging 132kV OHL strings. PACE is providing full suspension and tension string items including composite insulators, BS Fittings and Conductor fittings. PACE is also working with Western Power Distribution’s contractors to supply equipment for projects awarded directly to the contractors. Due to our stocking policy, PACE could deliver more than 400 insulators and associated fittings – directly from our UK stores to site in-order to maintain the tight outage dates.
Vibration Dampers into a Western Power Distribution Project
PACE Networks and RIBE, one of our leading European partners, carried out the Vibration Study and successfully supplied more than 1,000 bolted Lynx Vibration Dampers to Omexom for a Western Power Distribution 132kV re-stringing project, within a constrained project programme tied to a fixed already booked schedule of outages.
Development of a 275 kV Prototype
PACE Networks is currently working close to one of the largest Overhead Line Designer’s Energy within the UK for the product development, supply and technical support in the development of a 275 kV Prototype steel pole with the capacity of holding Totara conductor and Keziah earth wire and the further development of the method statement for the construction works. Delivery of prototype samples are planned for Q4 2017.
