There are two main types of switchgear p longchamp shopping tote ower systems: gas insulated and air insulated. Switchgear is a term used to describe the combination of fuses and circuit breakers that are needed to single out electrical equipment in order to power it off for repair or adjustment and to separate areas further down the power line so that if repairs do need to longchamp shopping tote be done, there is no interruption in service where there doesnt directly need to be.



However, there is also a large debate as to which switchgear system is more effective and which is safer to use for the environment.



Gas insulated switchgear systems are quite efficient in that they require a very small amount of space to operate and the equipment is relatively inexpensive to operate. This allows for use in areas of high population and in areas where it is more eyepleasing to use a smaller system, such as department stores, highrise buildings, industrial plants or mobile units.



However, with the use of the gas insulated switchgear system also comes the emission of sulphur hexafluoride. While sulphur hexafluoride is a nontoxic, odourless and nonflammable gas, it is also what is called a greenhouse gas, which is known to be harmful to the earths ozone layer. Many environmentalists oppose the use of these types of switchgear systems because of that, even though this particular gas contributes to only .05% of the greenhouse gases emitted. These emissions have also been cut by about 40% since 1995 and there is always work that is being done to reduce them even further.



The air insulated switchgear systems can come with a slightly higher price tag than the gas systems. They are larger and can cost more to operate, leaving little room for them in the more compact areas in which their counterparts can fit.



While these switchgear systems have been found to be more environmentally friendly because, honestly, what could be more environmentally friendly than air?, their size and the sheer cost of operating such bulky machinery is often a deterrent to having them in smaller areas of business and residential housing, such as apartment buildings.



When all of these things are taken into consideration, it ultimately becomes a debate on which switchgear system is able to provide people with the capabilities that are needed coupled with the environmental responsibilities that come along with the service.



Of course, while it is important to keep the greenhouse emissions as low as possible, and these environmental responsibilities belong to us all, the amounts that are released with the gas switchgear systems hardly seems to be a noticeable culprit if you look at the totals from all other sources. longchamp shopping tote
