Recently, the 2026 Standard Formulation and Revision Working Group Meeting of the National Technical Committee on Low-Voltage Switchgear and Controlgear Standardization (SAC/TC266) was held in Suzhou. NATUS Electric was invited to attend and deeply participated in the revision discussion of two national standards for low-voltage switchgear assemblies, GB/T24275 and GB/T24274. This is authoritative recognition of NATUS's technical strength by the industry, and marks NATUS's evolution from a standard follower to a standard-setter.

Insight into Industry Trends: Interpreting New Changes in National Standards

Every iteration of standards represents an upgrade of industry technology routes and safety concepts. The two national standards under revision target the two mainstream forms of current low-voltage switchgear assemblies — fixed enclosed type and withdrawable type. The core of the revision lies in:

1. Stricter Environmental Adaptability Requirements：The new standard draft puts forward higher requirements for equipment protection performance (such as IP rating), corrosion resistance, and weather resistance under harsh outdoor conditions. This reflects the urgent demand for "full-working-condition safety" of power distribution equipment in scenarios such as new energy, data centers, and industrial plants.

2. More Comprehensive Technical Indicator System：Compared with the original standard (2019 version), the 2026 revision draft further aligns with the latest GB/T7251 series general standards in core parameters such as electrical clearance, creepage distance, dielectric performance, and short-circuit withstand strength, achieving a deep closed loop from "single product standard" to "system safety standard".

3. Clearer Test and Verification Requirements：The new standard refines specific methods for temperature rise tests, protection circuit effectiveness verification, mechanical operation tests, etc., enhancing the operability and standardization of the standards and setting a higher threshold for equipment quality consistency.

 【 Market Interpretation 】

The above changes ultimately point to one trend: medium and low voltage power distribution equipment is accelerating toward the direction of "high density, high reliability, maintenance-free, and full-working-condition". NATUS Electric's deep participation in this revision ensures that our product R&D always resonates with the latest requirements of national standards, and even stays moderately ahead.

Leading National Standards, Pioneering  Group Standard 

While actively participating in national standard revision, NATUS Electric has proactively established a portfolio of group standards. Our company has participated in the formulation of 9  group standard (covering the field of medium and low voltage switchgear equipment), with NATUS serving as the initiating unit for 3 of them. All 9 standards have been officially released.

        1. T/CASME 2019-2025 Technical Specification for Digital Operation and Maintenance and Intelligent Sensing System of High and Low Voltage Switchgear

        2. T/CASME 2031-2025 Technical Specification for Modular Compact Intelligent Integrated Box-Type Substation

         These two standards directly address industry pain points:

        1. Digital Operation and Maintenance: Defines the intelligent requirements for switchgear condition monitoring (temperature rise, partial discharge, mechanical characteristics), laying the foundation for predictive maintenance.

        2. Modular and Compact: Responds to the core demands of data centers and new energy stations for small footprint, fast deployment, and high integration of equipment.

      【 Market Value 】

        While peers are still catching up with basic national standards, NATUS has taken the lead in defining the product value of "intelligent, compact, digital operation and maintenance" through participating in group standard, delivering added value beyond standard requirements for customers.

Standards-Driven Products, Empowering with Real Strength

The value of standards lies in execution. NATUS Electric integrates technical insights from standard discussions into product development in advance:

1. NATUS C-GIS Gas-Insulated Switchgear: Fully conforms to the industry trend of "high density, fully enclosed, maintenance-free", and is an ideal power distribution solution for data centers, offshore wind power and other scenarios.

2. Intelligent Low-Voltage Switchgear System: Built-in intelligent sensing units that comply with the "Digital Operation and Maintenance" association standard, realizing the upgrade of operation and maintenance mode from "passive maintenance" to "active early warning".

3. Our commitment: Relying on in-depth understanding of national and group standard, NATUS Electric can provide customers with not only compliant products, but also systematic guarantees of "compliant design, sophisticated manufacturing, and intelligent foresight".

【 Future Innovation 】

Standards are the universal language of the world and the touchstone of an enterprise's technical strength. In the future, NATUS Electric will continue to deeply participate in the formulation and revision of standards at all levels, integrating rich practical experience and cutting-edge technology exploration into standards, and providing users with safer, more reliable, and more intelligent power distribution solutions. NATUS Electric — leading with standards, building a reliable future through smart manufacturing.
