railway CIRCUIT BREAKER gas system Situation
railway CIRCUIT BREAKER gas system SituationMar 20, 2013Due to its low gaseous viscosity, SF6 gas can efficiently transfer heat by convection. So due to high dielectric strength and high cooling effect, SF 6 gas is approximately 100 times more effective arc quenching media than air.. Due to these unique properties of this gas, SF6 circuit breaker is used in a complete range of medium voltage and high voltage electrical power system.

railway sf6 Rules Disadvantage
Jul 14, 2015Sulphur hexaflouride (SF6) gas has been used in MV and HV switchgear for many years. It is said to be highly toxic and a potent greenhouse gas. It is used because of its excellent electrical insulation properties, but recently some switchgear companies have suggested other solutions. In our virtual panel discussion we asked some specialists […]

high voltage Ring network cabinet Purpose
Estimated Reading Time: 1 minPublished: 22/11/2017OverviewIn an electrical power distribution system, a ring main unit (RMU) is a factory assembled, metal enclosed set of switchgear used at the load connection points of a ring type distribution network. It includes in one unit two switches that can connect the load to either or both main conductors, and a fusible switch or circuit breaker and switch that feed a distribution transformer. The metal enclosed unit connects to the transformer either through a bus throat of standardized dimensions, or else through cables and is usually installed outdoors. Ring main cables enter and leave the cabinet. This type of switchgear is used for medium voltage power distribution, from 7200 volts to about 36000 volts. The ring main unit was introduced in the United Kingdom and is now widely used in other countries. In North American distribution practice, often the equivalent of a ring main unit is built into a pad mounted transformer which integrates switches and transformer into a single cabinet.

Nov 01, 2018When it comes to handling gas, safety should always be your top priority. Sulfur hexafluoride, or SF6, is a colorless, odorless, non flammable, extremely potent greenhouse gas and is an excellent electrical insulator. Although it is not a toxic gas, exposure to pure SF6 gas can cause suffocation, eye irritation, skin rashes and chemical burns.

guide GAUGE
Gauge is a measure of the number of stitches in one inch of fabric. Gauge is essential in knitting and you will see it referenced in a number of places. Once you have selected a pattern to knit, look for the designer's given gauge. This can usually be found at the start of the pattern, near the yarn and needle requirements.
