Segmentation Analysis

By Type

Rapid Adoption of Air-Insulated Substations (AIS) in Grid Modernization to Augment the Segment Growth

Based on type, the market is classified into Gas-Insulated Substations (GIS), Air-Insulated Substations (AIS), and hybrid substations. The air-insulated substations segment dominated the market share owing to its cost-effectiveness, ease of maintenance, and simpler design. Moreover, in grid modernization projects, substations with open-air design allow easy visual inspection and fault detection, reducing the need for specialized tools and personnel. AIS uses atmospheric air as the insulation medium between electrical components.

• For instance, in August 2023, GE Vernova’s Grid Solutions planned to supply two 500 kV air-insulated substations (AIS) to the municipalities of Currais Novos and Sao Tome, both in Rio Grande do Norte (RN) and a connection bay in Santa Luzia, Paraiba (PB).

The Gas-Insulated Substations (GIS) are anticipated to grow steadily as GIS uses a sealed environment filled with sulfur hexafluoride (SF6) gas as the insulating medium, allowing for compact designs and reduced environmental impact. GIS offers compactness, reduced footprint, enhanced reliability, and lower maintenance requirements compared to AIS.

• For instance, in January 2025, the Punjab State Transmission Corporation Limited, India, announced the development of a new 220 KV gas-insulated substation with a cost of USD 6.9 million equipped with over 10,000 industrial units located in Ludhiana, Punjab.

By Voltage

Growing Need for Efficient Energy Distribution to Fuel Medium Segment Growth

Based on voltage, the market is classified into low, medium, and high.

In distribution substations, Low Voltage (LV) typically refers to voltages up to 1000V, Medium Voltage (MV) between 1000V and 45kV, and High Voltage (HV) between 45kV and 230kV, with Extra High Voltage (EHV) being above 230kV.

The medium segment accounts for a major share due to its versatility in distributing power from substations to end-users across various sectors. It offers a balance between equipment size, efficiency, and reliability. These substations are used for short-distance power distribution, where voltages are not high enough to warrant a high-voltage substation.

They connect High Voltage (HV) power lines to Low Voltage (LV) distribution networks. Distribution substations act as a crucial link between high-voltage transmission networks and low-voltage distribution networks, converting high voltage to lower voltages suitable for homes and businesses and ensuring reliable and efficient power delivery.

By Insulation

Rising Adoption of Solid Insulation Segment in Renewable Energy Sector to Boost Market Growth

Based on insulation, the market is segmented into solid insulation, liquid insulation, and gas insulation. Among these, solid insulation emerged as the dominant segment and holds the largest market share. In distribution substations, insulation can be achieved using solid, liquid, or gas mediums, with solid insulation often found in cables and bushings, liquid insulation in transformers and cables for cooling and insulation, and gas insulation, especially SF6 gas, used in compact, high-voltage gas-insulated switchgear (GIS). It utilizes solid materials such as epoxy or polyurethane resin to separate and support electrical conductors.

• For instance, the solid insulation distribution substations offer superior electrical & thermal insulation, reliability, and safety, which is crucial for the intermittent nature of renewable energy sources, namely solar and wind.

By Application

High Demand for Distribution Substations in Utility Sector to Drive Market Share

Based on application, the market is segmented into industrial, commercial, and utility. The utility segment dominated the market. This dominance is attributed to the increasing demand for uninterrupted power supply and the growing need for efficient and reliable power grids. The utility sector widely uses distribution substations to safely & efficiently deliver electricity to the end-users. Also, by stepping down the voltage levels, these substations can minimize the power loss during distribution over shorter distances.
