Insulated Switchgear (GIS) is vital equipment in electrical substation. It is a
metal enclosed switchgear, comprising of components such as dis-connectors and
circuit breakers. It is largely used in places where space is limited. It is
installed or connected on the extensions in areas for instance roof, industrial
plants, offshore platforms, and hydro power plants, among others. It provides
the space efficient and maximum cost effective solution in order to enhance the
overall efficiency.
The
key features are included high reliability, high degree of safety, long service
life economic efficiency, high availability,
compact design, and little maintenance requirements.
Based
on type, GIS market is segmented into medium voltage GIS and high voltage GIS.
Medium voltage GIS includes primary distribution medium voltage GIS and
secondary distribution medium voltage GIS. Medium voltage GIS segment dominates
the market owing to growth in development in the power distribution sector
through the implementation of smart metering and smart grid technology. Based
on capacity, market is segmented into < 38 kV, >38kV to <72kV,
>72kV to < 150kV and >150 kV. Based on voltage, market is segmented into
high voltage transmission, sub-transmission voltage and distribution voltage.
High voltage transmission is further sub-segmented into extra high voltage
transmission and ultra-high voltage transmission. Based on installation, market
is segmented into outdoor GIS, indoor GIS and solid bus duct connection &
cable connection. Based on technology, market is segmented into compact GIS,
integrated 3 phase GIS, and hybrid GIS. In addition, based on end-user, market
is segmented into infrastructure & transportation, power distribution
utilities, power transmission utilities, power generation utilities and
industries & OEMs. Industries & OEM s include oil & gas, marine,
mining, manufacturing & process industries, heavy industries and others.
The
GIS market is driven by increase in share of renewable power generation,
followed by rise in energy demand & limitations of space availability in
densely populated urban areas, growth in investments in the transmission &
distribution (T&D) infrastructure, rise in power consumption, growth in
industrialization & infrastructural developments and rise in government
initiative toward improving electricity access. However, delays in grid
expansion projects and high cost of equipment may impact the market. Moreover,
rise in investments in smart grids & energy systems, extension or
replacement of old switchgear at substations in developed regions and growth in
adoption of the high voltage direct current (HVDC) technology are key
opportunities for market.
Based
on geography, the Asian-Pacific is a leading region in GIS market owing to rise
in demand for electricity and large population in the region. The
North-American and European regions are anticipated to witness higher growth
rate due to strict regulations imposed by the government and up-gradation of
power grids with new & advanced variants over the forecast period. In near
future, it is expected that the market will be reached at quick pace as a
result of rise in renovation of transmission lines during the forecast period.
