Environmentally friendly ring main unit: leading the green revolution in global power distribution systems

Introduction

With the global emphasis on carbon neutrality and energy transition, the traditional use of SF₆Gas-fired power equipment is gradually being replaced by "environmentally friendly alternatives" SF₆(Sulfur hexafluoride) has excellent insulating properties, but its greenhouse effect potential is 23,500 times that of carbon dioxide, causing long-term environmental impacts.

Countries have successively introduced restrictive policies:

The European Union (EU) plans to phase out SF by 2030₆Equipment:

Japan and South Korea launched environmentally friendly gas alternative standards;

Southeast Asian countries are introducing more green power technologies and equipment

Against this background, Eco-Friendly RMU has become the mainstream direction for upgrading medium-voltage power distribution systems.

1. What is an environmentally friendly ring main unit?

Environmentally friendly ring main unit (Eco-Friendly RMU) refers to the use of environmentally friendly insulating media (such as dry air, nitrogen, C5F100, CF₃I or mixed gas) instead of SF₆medium voltage power distribution equipment.

It is mainly used in urban distribution networks, industrial parks, renewable energy power stations, rail transit and other scenarios, and has the following core features:

• Zero greenhouse gas emissions: SF6-free and environmentally friendly.
• High safety and reliability: Insulation performance meets IEC 62271 series standards.
• Maintenance-free design: fully sealed structure, no need for regular air replenishment.
• Intelligent compatibility: supports remote monitoring and smart grid access.
• 4. Low life cycle cost: lower comprehensive maintenance and recycling costs.

3. Global market prospect analysis

Policy promotion

The EU will restrict SF from 2026₆When used in power equipment, the United States, Japan and other countries have also successively introduced relevant bans and replacement plans. This means that the environmentally friendly ring main unit market will usher in a period of rapid growth.

Industry needs

Global distribution network construction continues to grow, especially new energy power generation (wind energy, solar energy) grid-connected projects, and the demand for environmentally friendly switchgear has increased significantly.

market forecast

According to ResearchAndMarkets data, there will be no SF in the world from 2024 to 2030.₆. The compound growth rate (CAGR) of the ring main unit market is expected to exceed 10%, making it one of the most potential market segments in the field of power equipment.

4. Application scenarios

• Urban power distribution system: replacing traditional SF in new construction and renovation projects₆Ring main unit.
• Wind power and photovoltaic power stations: meeting the needs of green energy grid connection
