Over 50% of the population live or work on or above the 15th floor and more than 60,000 lifts are in use every day. Our airport, railway and banking networks also require a reliable power supply. This is made possible by the dedication of engineers behind the scene, who help make Hong Kong Asia’s World City.
CLP manages over 13,900 substations, and most of them are interconnected for real-time control. Engineers do not have to stay at the substations, as they mostly work on shifts to man the control room instead, 24 hours a day, 7 days a week, maintaining the reliability of power supply.
High-voltage cables are usually made of highly conductive copper wires coupled with semi-conductors and insulators. Their various forms such as underground cables, submarine cables and overhead cables are commonly used for effective and safe power transfer over long distances.
'To go undercover' refers to the laying of underground cables.
When engineers say 'cattle', they actually mean a large power transformer. Accordingly, a substation equipped with power transformers is dubbed a 'cattle farm'. A major function of a substation is to ensure stable power transmission from network to other buildings.
The short form of 'Engineer' is 'Ir'. Among the different types of engineers are electrical engineers, civil engineers, geotechnical engineers, computer science engineers and chemical engineers.
Some inventions by engineers that have shaped modern life are: the spaceship, the world’s first Internet search engine, the electric motor, the ski board and the boomerang.
