SPONSORS INSTALLATION NEWS
Cable cleats designed and manufactured in Yorkshire by Ellis have been specifled and installed by the US Army Corps of Engineers (USACE) at the Fort Randall dam in Pickstown, South Dakota.
The Fort Randall Dam Pipe Cable System Replacement project is being overseen by the USACE and involves the removal of 48,000ft of single conductor oil impregnated paper insulated copper cable, eight oil filled pipe cables and 8,000ft of steel pipe; and the subsequent installation of 48,000ft of single-conductor copper cable with 133% EPR insulation, including 96 total 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.
“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 project is due for completion in September 2019.

Sustainability was a key priority for the £28m Oastler Building, and the high-efficiency TROX air handling units at the heart of the HVAC system are contributing to the energy efficiency of the building, which has achieved a BREEAM Excellent rating. Forming part of Huddersfield university’s Queensgate campus, the new Oastler building houses the Law School and parts of the School of Music, Humanities and Media. It includes four 300-seat lecture theatres, tutorial spaces, offices, language labs and a mock court room, along with open plan communal spaces.
uTROX’s XCUBE air handling units have been installed at the University of Huddersfleld’s awardwinning Oastler building.
Designed by AHR, the building’s curved frontage faces onto Huddersfield's ring road with a 3.5m cantilever across six storeys, defined by 42 fins rising over the upper levels. Air handing and ventilation demands vary from dynamic social spaces and lecture rooms, to long, tall corridors and individual study booths for language students requiring sound attenuation.
The outstanding energy efficiency of the
TROX X-CUBE air handling unit was a key factor in its selection for this project. The X-CUBE’s integral variable flow control technology facilitates room- by-room air management, adjusting automatically to requirements.
Designed to connect seamlessly to a centralised BMS (via Modbus TCP, Ethernet or BACnet), the X-CUBE’s built-in control technology (available as standard) avoids the need for complex or expensive bespoke programming of the BMS. Intelligent control and highly-efficient IE4 motors also contribute to outstanding energy performance. Quality of manufacture was another key factor. The X-CUBE’s enclosure incorporates special construction and insulation features to ensure low leakage and optimised heat recovery. In addition, the TROX attenuators, with aerodynamically profiled frames, achieve 30% less pressure drop than conventional silencers.

LED Eco Lights, the award winning UK LED lighng manufacturer, has announced that Network Rail has fled its Goodlight LED lighng on all 18 plaorms and the concourse at London’s Liverpool Street Staon.
Goodlight gives more light for less at Liverpool Street Staon
Passengers and staff are benefiting from higher, better quality lighting at Liverpool Street Station, while Network Rail is making significant savings in electricity costs and a reduction in its carbon footprint. Adam Thackeray, Works Delivery Manager for Network Rail, commented: “We decided to move to LED lighting to reduce our carbon output, reduce costs in terms of power consumption and to improve the lighting level and quality in public areas of the station.
“The opportunity to reduce costs for lamp replacement by moving from a two year to a five year cycle was also a significant consideration. LED lighting will also increase the efficiency of emergency lighting, reducing the load on the battery/generators and reduce the temperature signatures of lighting and heat related failures.” The Goodlight LED lamps can easily be retro-fitted into the existing fittings, allowing relamping to proceed with little disruption. More than 3,500 lights were replaced by operatives working from two scissor lifts on a permanent night shift during the five hour window offered by station closing hours over a six month period.
Some commuters shared Tweets about the improvement and many of the station’s staff expressed appreciation for the improved station environment.
TROX XCUBE air handling units have been chosen to deliver outstanding environmental performance in an awardwinning new building belonging to the University of Huddersfleld.

Liverpool Street Station is seeing both an increase in light levels and a reduction in energy demand following the relamping with Goodlight LED. The station has measured an increase in Lux levels on the platforms and concourse, from approximately 75 Lux with the old lighting to 210 Lux with Goodlight.
uGoodlight G360 LED SON lamps were installed at Liverpool Street Staon.
At the same time there has been a temperature drop of approximately 40C at the exterior of the globe fixtures, which should improve reliability as well as efficiency.
During the replacement of the concourse lighting in particular, maintenance teams noticed that there was a lot of the discolouration around the lamps and reflectors caused by heat produced by the old fluorescent lamps and control gear. This illustrates both the amount of waste heat generated and the issues it was causing. The energy saving from the new lights is over 800,000 kWh per year from the platform globe fixtures alone. Adam Thackeray estimates that the new LED lighting uses about half the energy of the old lights, and will pay for itself in just 12-18 months.
