InstallationNews Ellis secures US Army civil works project
Cable cleats designed and manufactured in Yorkshire by Ellis have been specified and installed by the US Army Corps of Engineers (USACE) at the Fort Randall dam in Pickstown, South Dakota.
T
he Fort Randall Dam Pipe Cable System Replacement project is being overseen by the USACE and involves the removal of
48,000ſt of single conductor oil impregnated paper insulated copper cable, eight oil filled pipe cables and 8,000ſt of steel pipe; and the subsequent installation of 48,000ſt of single-conductor copper cable with 133% EPR insulation, including 96 class 3- 15kv cable terminations. Tony Conroy, Global Sales Director of Ellis, said: “The US Army Corps of
Engineers had heard of our Centaur cable saddle, knew of our expertise in developing innovative project specific solutions, and contacted our US distributor, NASCO with a view to discussing the development of a bespoke solution for this particular project. “The job itself proved extremely challenging, not least because of the tight constraints of the existing support structure. But by working together, the combined experience of the USACE engineers and our in-house design team meant we were able to arrive at and then deliver the perfect solution for the project.” The original idea for the Fort Randall project was to use a fixed cable
tray/roller system, but the cable movement caused by thermodynamic forces meant that a snaked system was found to be more appropriate. Ellis’ bespoke solution required USACE modifications to the existing steel angle supporting structures to accommodate both its Centaur cable saddles and Centaur anchors.
Installed in America – Ellis’ Centaur cable saddles. “The scale of the project needs to be seen to be believed,” added Tony.
“For example, the eight oil filled pipe cables removed contained 24,000 gallons of insulating oil; and some of the circuits were an astonishing 1,500ft long.” The contractor for the Fort Randall Dam project was Colorado-based
Interstate Electrical Contractors Inc., and the order was placed through Ellis distributor, California-based NASCO (North American Sales Company Inc.). The project is due for completion in September 2019.

Thorn Lighting is the sole lighting supplier for both interior and exterior areas of The Archbishop Lanfranc Academy’s new £multi-million building in Croydon. Thorn worked with Halsion Building Service Engineers to deliver an energy efficient, future-proofed facility.
A
rchbishop Lanfranc Academy’s previous home, constructed above a
landfill site in the 1950s, was outdated and dilapidated and was demolished to make way for a new Academy. Together with the new sports hall, fitness
suite and dance studio, the four-storey, 11,796sq m building offers students and staff a state of the art environment. Thorn’s Arena Symphony innovative LED luminaires with sound absorbing features were chosen to minimise sound reverberation in the classrooms. Fully compliant with BB93 for optimum
classroom performance, Arena Symphony has been designed for total flexibility, offering a choice of infills to adapt the length of the system to match all classroom layouts. Slim profile, 600 x 600 Omega PRO LED

LED lamps supplied with the fitting. Hi Pak Pro LED, a highly efficient, robust and low maintenance high bay has been utilised in the sports hall to achieve significant energy savings and low maintenance due to the on board thermal management system that
ensures LED performance and a lifetime of over 50,000 hours. College LED curved profile, linear fluorescent luminaires were selected for the dining areas, communal hall and parts of the offices. The IP44 rated fitting has a clear prismatic diffuser in tough polycarbonate for specific light control and the impact/vandal resistance perfect for teaching establishments. Thorn’s CiviTEQ, Deco LED and Eyekon fittings have been used for the external illumination to create an attractive and welcoming appearance for the academy. The compact and lightweight CiviTEQ is a well- proportioned LED road lantern with an unobtrusive style that is fitted with an R-PEC optic to provide safe and efficient illumination. Energy efficient, robust and impact resistant Eyekon LED bulkheads and Deco bollards complete the clean and modern illumination of the exterior of the building.
