Development Trends in The Medium-Voltage Electrical Equipment Industry - News

Our country's medium-voltage electrical equipment industry is currently undergoing a technological paradigm shift, accelerating its evolution toward intelligent and digital systems, green and low-carbon solutions, and supporting infrastructure for AIDC (AI Data Centers) and computing power. Key development trends include:

Why discharge residual voltage (10kV)?

1. Intelligent and Digital Upgrades

Driven by smart grid construction and digital transformation, medium-voltage equipment is advancing toward digitalization and information integration.

Integration of Primary and Secondary Equipment & Online Monitoring: Intelligent switchgear technology continues to evolve; smart vacuum circuit breakers featuring online monitoring capabilities-capable of tracking key metrics such as vacuum levels, contact heating, and partial discharge-are seeing rapid adoption.

High-Frequency Power Electronics Transition: With 2026 marking the start of large-scale commercialization for Solid-State Transformers (SSTs), the industry is shifting its technological paradigm from traditional power-frequency transformer manufacturing to the integration of high-frequency power electronic systems.

2. Green, Low-Carbon, and Eco-Friendly Alternatives

Driven by environmental policies and "Dual Carbon" goals, the industry is rapidly reducing its reliance on traditional insulating gases.

Eco-Friendly Gas Alternatives: Traditional sulfur hexafluoride (SF₆) products are being phased out rapidly, while SF₆-free eco-friendly Ring Main Units (RMUs) and solid insulation technologies are being fast-tracked to market.

Low-Loss Transformers: Medium-voltage distribution transformers are evolving toward low-loss, high-efficiency energy-saving products-such as amorphous alloy transformers and prefabricated substations-to reduce overall line losses in distribution networks.

3. New Growth Driven by AIDC and New Energy Support

Structural changes in electricity demand are injecting new growth momentum into the industry.

Computing Infrastructure Demand: The rapid expansion of data centers (AIDC) is driving a restructuring of medium-voltage power distribution architectures, fueling sustained demand for high-power-density AIS (Air-Insulated Switchgear) cabinets and OEM cabinets from foreign brands. New Energy and Industrial Retrofitting: Products such as medium-voltage vacuum circuit breakers and contactors hold significant market potential in supporting new energy infrastructure, upgrading manufacturing facilities, and retrofitting existing systems (including capacitor banks and high-voltage variable frequency drives).

4. Global Competition and Domestic Substitution

Market competition is intensifying, with domestic brands accelerating their expansion into overseas markets and high-value-added sectors.

Domestic Substitution and Technological Breakthroughs: The industry is gradually reducing its reliance on imported core components, as the reliability and service life of domestic products rapidly catch up to international standards.

Supporting Overseas Expansion and New Voltage Levels: Chinese brands are accelerating their global expansion by meeting local requirements in overseas markets; meanwhile, 24kV/20kV power distribution equipment-which simplifies distribution networks and enhances energy efficiency-is seeing increasingly widespread application.
