Based on current situation and impact historical analysis (2021-2025) and forecast calculations (2026-2032), this report provides a comprehensive analysis of the global Environmentally Friendly GIS Tank-Type Lightning Arrester market, including market size, share, demand, industry development status, and forecasts for the next few years.
For grid operators, substation engineers, and power infrastructure developers, the challenge of protecting critical electrical equipment from lightning strikes and switching overvoltages must be balanced with growing regulatory pressure to phase out sulfur hexafluoride (SF₆)—a potent greenhouse gas with a global warming potential 23,500 times that of CO₂. Traditional gas-insulated switchgear (GIS) and associated surge arresters have relied on SF₆ for decades, but the environmental imperative to reduce SF₆ emissions has accelerated the development of alternative insulating gas mixtures. Environmentally friendly GIS tank-type lightning arresters address this dual requirement through high-performance overvoltage protection devices designed specifically for gas-insulated switchgear systems that utilize SF₆-free insulating gas mixtures (such as g³, N₂/CO₂, or other eco-friendly alternatives). Using metal oxide varistors (MOVs) as the core active element, these arresters rapidly conduct and absorb energy during lightning strikes or operational overvoltages, limiting voltage amplitude to protect GIS, transformers, circuit breakers, cable terminals, and other critical electrical equipment. Housed within sealed tanks filled with environmentally friendly mixed insulating gases, these arresters deliver compact footprint, superior insulation performance, fast response speed, high reliability, and maintenance-free operation—making them essential components for modern substations, power plants, industrial power distribution systems, subway traction power supplies, high-rise buildings, and data centers.
The global market for Environmentally Friendly GIS Tank-Type Lightning Arrester was estimated to be worth US$ 209 million in 2025 and is projected to reach US$ 359 million by 2032, advancing at a CAGR of 8.2% from 2026 to 2032. In 2025, global production reached 35,790 units, with an average selling price of US$ 5,840 per unit.

Product Definition: SF₆-Free Overvoltage Protection for GIS
Environmentally friendly GIS tank-type lightning arresters are overvoltage protection devices specifically designed for installation within gas-insulated switchgear systems that use alternative insulating gases. Key technical characteristics include:
Metal oxide varistor (MOV) core: Zinc oxide (ZnO) varistor elements provide superior non-linear voltage-current characteristics, enabling rapid conduction during overvoltage events and near-zero leakage during normal operation. These elements absorb surge energy while clamping voltage to safe levels for downstream equipment.
Eco-friendly insulating gas environment: Unlike traditional GIS arresters that rely on SF₆, environmentally friendly units operate in alternative gas mixtures:
- g³ (Green Gas for Grid): A fluoronitrile-based gas mixture with global warming potential (GWP) < 1 compared to SF₆’s 23,500
- N₂/CO₂ mixtures: Simple gas blends offering environmental advantages with established safety profiles
- Other alternative gases: Fluoroketones, fluoroethers, and other low-GWP insulating gases
Tank configuration options:
- Built-in type: Integrated within the same gas chamber as the main GIS equipment, optimizing footprint and reducing gas compartments
- Independent chamber type: Self-contained gas compartment that can be serviced independently without affecting main GIS operation
- Modular combination type: Standardized units that can be combined for higher voltage ratings or redundancy requirements
Key performance attributes: Compact size (30–50% smaller than air-insulated alternatives), superior insulation performance (maintaining dielectric strength comparable to SF₆ systems), fast response speed (nanosecond-scale conduction), high reliability (service life exceeding 30 years), and maintenance-free operation.
Exclusive Industry Insight: The SF₆ Phase-Out Imperative
A distinctive observation from our analysis is the accelerating regulatory and policy-driven phase-out of SF₆ as the primary market catalyst for environmentally friendly GIS tank-type lightning arresters:
EU F-Gas Regulation has progressively restricted SF₆ use, with bans on new equipment in medium-voltage applications (effective 2026) and increasingly stringent phase-down schedules for high-voltage equipment. Similar regulatory frameworks in the UK, Japan, and other regions are creating demand for SF₆ alternatives.
Corporate sustainability commitments from grid operators and industrial users are accelerating adoption. Major utilities (including EDF, TenneT, and national grid operators) have announced targets to reduce or eliminate SF₆ from their networks, driving procurement of SF₆-free equipment.
Carbon pricing mechanisms make SF₆ emissions increasingly costly. With carbon prices rising in Europe and other markets, the cost of SF₆ leaks—both financial and reputational—provides additional impetus for transition to alternative gases.
Infrastructure expansion in emerging markets presents an opportunity to leapfrog SF₆ technology, deploying environmentally friendly GIS from the outset rather than retrofitting existing installations.
Market Drivers: Grid Expansion, Renewable Integration, and Environmental Compliance
The environmentally friendly GIS tank-type lightning arrester market is propelled by several converging factors:
Grid modernization and expansion across developed and emerging markets drives demand for GIS equipment. Urbanization and land constraints favor compact GIS solutions, with environmentally friendly arresters capturing an increasing share of new installations.
Renewable energy integration—particularly offshore wind, solar, and battery storage—requires reliable overvoltage protection. Renewable generation facilities are often located in environmentally sensitive areas or require compact footprints, making GIS with SF₆-free arresters an attractive solution.
Data center and critical infrastructure growth creates demand for high-reliability power distribution. Data centers, high-rise buildings, hospitals, and other critical facilities require overvoltage protection with minimal maintenance and high availability.
Environmental compliance requirements increasingly specify SF₆-free equipment. Grid operators and industrial users are adopting procurement policies that favor environmentally friendly alternatives to manage regulatory risk and meet sustainability targets.
Technology Trends: Higher Voltage Ratings, Condition Monitoring, and Integration
Higher voltage ratings for environmentally friendly GIS arresters are expanding application range. While early products focused on medium voltage (up to 72.5 kV), manufacturers are developing arresters for high-voltage (up to 145 kV) and ultra-high-voltage applications, capturing the full GIS market.
Condition monitoring and smart grid integration is becoming standard. Integrated sensors for leakage current, temperature, and partial discharge provide real-time status information, enabling predictive maintenance and integration with grid management systems.
Modular design enables standardization and reduced cost. Interchangeable components and standardized interfaces simplify procurement, installation, and maintenance for utilities managing large GIS fleets.
Market Segmentation and Competitive Landscape
By configuration, the market is segmented into built-in type, independent chamber type, and modular combination type. Built-in types dominate new GIS installations where integration reduces footprint; independent chamber types are preferred for retrofits and applications requiring service flexibility.
