gaz sf6 circuit breaker maintenance | TD Guardian Articles

The first generation of gaz sf6 circuit breakers was the lower voltage classes of 72kV and 145kV. As sf6 gas breaker technology improved, circuit breaker manufacturers introduced a dual pressure design for 145kV through 800kV applications, as well as air-blast breakers utilizing Sulfr hexafluoride as the line-to ground dielectric insulation.

Case study of water supply and sanitation infrastructure

Water in Hong Kong. Hong Kong is a relatively small territory which has no adequate sources of water from underground, natural lakes or large rivers. As a result, the infrastructure to supply Hong Kong with drinking water has been extensively designed to minimise the amount of water required, and to ensure an adequate supply can be maintained.

WSD - Seawater for Flushing

Further Extension of Seawater Supply NetworkQuality of Seawater For FlushingConversion to Seawater For FlushingIn 2015, the WSD successfully expanded Hong Kong’s seawater supply coverage to 85% of the population. At present, seawater is available to buildings in Northwest New Territories (including Tuen Mun East, Hung Shui Kiu, Tin Shui Wai and Yuen Long Town Centre) and Pok Fu Lam for flushing. We will further extend the seawater supply network to Tung Chung. On the other hand, since some of the inland areas (e.g. the North District) are distant from the coast, the construction of a seawater supply system at this stage is uneconomical. Yet, we will review this issue proactively, and, whenever technically feasible and cost-effective, continue to expand our seawater supply system or exploit new water resources (e.g. reclaimed water) in order to further reduce the use of fresh water for flushing.
