Aggreko has launched a new 60kVA mobile generator to achieve stable two-phase voltage power for signalling projects and infrastructure maintenance in the rail sector.
The 690 V alternator has the flexibility to adjust output between 650 to 720 volts to compensate for voltage drop when transporting electricity to remote locations across long distances. This means that the optimum 650 volt output can be maintained at the point of connection.
The enclosed generator and alternator is configurable for standby purposes to auto-start when supply is required. By negating the need for a separate transformer, the generator is quick and easy to set up and is easy to operate. It also has a compact footprint.
It can be trailer-mounted for fast delivery and access to difficult-to-reach sites. This enables the generator to be moved around the rail network, as required. Units are also available for static use and can be supplied with a long-range fuel tank for extended requirements.
The new technology is adapted from a three-phase 690 V generator used in the wind power industry. The alternator is double coated to withstand the most arduous weather conditions.
Units have been acoustically optimised to provide industry-leading sound attenuation levels down to 65dBA at one metre.
Rail network operators are using the new technology for planned maintenance of 650 V IT signalling projects and back-up power for commissioning new signal systems, emergency power outages, and standby power on projects such as overhead line electrification and asset maintenance programmes. The power can be supplied from any two phases of the generator terminal block, or the 690V socket outlet can be used for quick connection of the load cables to the site.
John Anderson, Aggreko’s National Accounts Manager for Rail, said: “This new technology provides a simple integrated solution to maintaining reliable frequency and voltage output for CP5 signalling projects and other critical applications. We have optimised our engine management system to minimise fuel consumption and emissions without sacrificing the power output.”
Aggreko also supplies standard canopy 240 V and 415 V generator and electrical distribution packages to support the latest signalling technology projects, transformer upgrades, telecommunications and maintenance projects.
Aggreko’s UK rail division has achieved a five-star accreditation in the Railway Industry Supplier Qualification Scheme (RISQS), which was formerly known as Achilles Link-up. It operates from 18 locations throughout the UK and Northern Ireland.
