Gas Insulated Transmission Lines Market size is slated to account for remunerative growth over 2021-2027 driven by the increasing usage of these lines in various infrastructure projects like nuclear power plants, hydropower dams, coal power plants, oil or gas power plants, and more. In addition, the expanding scope of industrialization and ongoing renewable energy applications worldwide is positive of transforming the gas insulated transmission lines market landscape through the coming years.
Gas insulated transmission lines (GIL) offer technical, operational, and environmental features which make them an ideal alternative in conditions where extra high currents and voltages are needed within the restricted space.
GILs come with various positive attributes like low capacitive load, low transmission losses, high reliability, increased level of personnel safety, no electric ageing, and others. These factors are expected to stimulate the product demand across various projects worldwide.
Restraints encountered by GIL manufacturers and suppliers include the use of Sulphur hexafluoride gas (SF6) as an insulation medium owing to its stable structure and exceptional properties. However, the introduction of certified second generation of GIL has significantly lowered down the use of SF6 gas. Reportedly, the 2nd generation of GIL is known to have a high global warming potential which is expected to pose threat to the environment, thus impeding its use globally.
Future applications of gas insulated transmission lines in railway and traffic tunnels are expected to pave way for the market progression in various urbanizing regions wherein the space constraints are relatively high.
Aboveground installation of gas insulated transmission lines is gaining prominence as it offers a trouble-free option and is suitable even for adverse environmental conditions. These lines also offer resistance against intensive solar radiation or severe atmospheric pollution owing to which they can be placed above the ground. Besides, for safety and security reasons aboveground installation is only used in secure regions like industrial plans and power substation or stations. The outer surface of these lines is generally grounded, which makes it safe to contact and streamlines mounting.
In the present scenario, DC gas insulated transmission lines offers a robust solution for underground installations. The reliability of AC gas insulated technology has indeed initiated changes in the development of DC gas insulated lines. Furthermore, DC installation is proven to be effective and cost-efficient for use at power plants and substations.
Regionally, China gas insulated transmission market is anticipated to churn out lucrative gains over the analysis period. This can be ascribed to the rapid urbanization and industrialization resulting in the rising consumption of high voltage electricity. Additionally, the country leads the hydropower sector demanding the deployment of gas insulated transmission lines. The rising demand from power transmission and generation sector is further likely to promote the GIL market growth across China.
Eminent players active in the global gas insulated transmission lines industry include Beta Engineering, Siemens AG, Grupo COBRA (ACS Group), L&T Construction, TBEA Energy, General Electric, AZZ Inc., Jiangnan Group Limited, and others. They are relentlessly striving to cut through the fierce competition through different strategic measures including mergers, collaborations, product launches and more.
Gas insulated transmission lines market has recorded a sluggish growth during 2020 owing to the COVID-19 pandemic outbreak. The downfall can be ascribed to the shutdown of various manufacturing plants and factories, disruptions in supply chain, movement restriction, and operation under reduced workforce. Various construction activities including railways, buildings, and other important projects had also been temporarily halted, affecting the sales of gas insulated transmission lines.
