PB Design has recently supplied Alstom Drives and Controls with a £400,000 package of 110V constant voltage battery chargers - complete with alarm, monitoring, distribution and nickel cadmium battery cells - for a major project on the Hong Kong Mass Transit Railway System.

Opened at the end of 1998 the new Hong Kong airport railway off the coast of Lantau island has taken five years to construct. Built for the Hong Kong Mass Transit Railway Corporation, the airport railway links Hong Kong Central and Kowloon with the new Chek Lap Kok airport. The Link incorporates the now famous landmark, Tsing Ma Bridge - the world's largest road and rail suspension bridge and the first to provide a truly all-weather crossing. Both Tsing Ma and its smaller, cable-stayed neighbour Kap Shui Mun Bridge carry the main highway on their top deck, while their sheltered lower level houses the railway plus two road lanes for use when the upper deck has to be closed in high winds.

PB Design's battery chargers are designed and manufactured to meet all the relevant British and International standards. Units can be floor standing or wall mounted and cover a voltage range from 12 to 220 volt DC output. The equipment utilises the company's 1500 range of constant voltage transformers, complete with digital Series 90 control system.

Following the success of this installation, a further order has been placed for similar equipment for the next phase.
