Indoor Switchgear Introduction
In general, switchgear is a comprehensive term used for the unit with combinational metering equipment types and a protective control as a whole. There can be various types of devices developed by the switchgear manufacturing companies in UAE that are used in different types of applications. There could be rail traction, motor protection, feeder protection, measurements, and other applications that are done with indoor switchgear. The switchgear installed at the electrical power substation can handle the functions, such as incoming feeder connectivity, switching the capacitor banks, control, and monitoring, measuring voltage and current, storage in a battery, etc.
The switchgear system has a direct linkage to the power supply system. It is placed at the low and high voltage sides of any power transformer. The purpose could be for testing, maintenance, or fault clearing of the equipment. Switchgear can be different as per the voltage levels and economical scope. The indoor switchgear is mainly used for medium voltages and is also termed as Mid-Voltage (MV Switchgear). It is enclosed in the metallic grounded enclosures with voltage levels from 3 – 36 kV (the range of medium voltages). The voltages higher than 36 kV can be employed as high voltages. The majority of the electrical switch gear companies in UAE work for indoor switchgear and we shall be discussing the indoor switchgear options in this article.
Indoor Switchgear Design
In comparison to the outdoor switchgear, the indoor variant mainly has GIS technology (Gas Insulated System) instead of the air-insulated system. GIS applies to the high-cost of lands and the areas with a lot of dust and corrosive environment. The arrangement of switchgear is enclosed in the well-grounded metallic enclosure on all the sides along with the openings aimed at inspection and ventilation. The units are insulated in a gaseous environment. Sulfur Hexafluoride gas (SF6) is preferred in this case for insulation with its dielectric properties. The dielectric strength of SF6 is much higher than that of air (3 times higher). The metallic enclosure provides a safe environment in comparison to the outdoor system.
The metal enclosure has two categories of indoor switchgear in terms of metal partitioning and switching methods:
1) Metal-enclosed indoor switchgear
This switchgear arrangement has the metallic sheets enclosed on all the sides with the primary interrupting equipment and fuses with all the equipment pieces encased in the centralized assembly. The access to the interior of the enclosure is provided by the doors and the removable coverings.
2) Metal Clad Switchgear
This switchgear type has the circuit breakers as the vacuum type and can be withdrawn from the original place. The grounded metallic barriers separately isolate the relaying and metering instruments. The main bus continuous ratings are 1.2 kA, 2 kA, 3 kA, and 4 kA with the voltage levels in the range of 4.76-38 kV.
Generally, all the metallic-clad switch gears are enclosed with metal but all the metal-enclosed do not come in the category of metal-clad switchgear. The advantages of metal-clad switchgear are much more than metal-enclosed switchgear. The metal-clad option can be easily customized as per the requirements and the best switch gear manufacturing companies in UAE could make attempts to do the needful as per the need of the clients. There is a pre-built to a customized range of indoor switchgear available that could be highly beneficial for the different uses.
Benefits of Indoor Switchgear
In comparison to the outdoor switchgear, there are indoor electrical switch gear companies in UAE defining the advantages of indoor switchgear over the other available options. Here are some advantages listed for the indoor switchgear:
- Lesser space requirements than outdoor systems
- Lower maintenance and operative costs
- Higher reliability and safety
- Secured and consistent
- Lower operational cost
- Reduced electrocuting risks due to the grounded metallic enclosures
- Durable systems
- Less environmental risk factors
Drawbacks of Indoor Switchgear
Despite having several positive points, the major disadvantage of Indoor switchgear, as mentioned by the tower light suppliers in UAE is that these come with the higher costs of installation. The economic factors play an important role and there is a high cost involved in the installation of the indoor switchers. The outdoor system or the air-insulated system becomes a choice for many for cost-effective choices. However, there are some diesel generator suppliers in UAE giving the most reliable and pocket-friendly solutions for the indoor switchgear.
Indoor switchgear system arrangements are more secured and reliable in comparison to the outdoor ones. However, the cost could be higher but ultimately, it is a better choice. It can even withstand severe weather conditions and works well in every atmosphere. The high voltage levels and economic factors are something to consider for indoor switchgear systems. Rest, all is just perfect with the indoor variant.
