Featuring characteristics such as safety and reliability, robust durability, standardized uniformity, universal interchangeability, rational grading, and broad applicability, the SLVA series complies with relevant national standards and CCC certification requirements.
The product meets the standards.
GB/T 7251.2-2023 "Low-Voltage Switchgear and Controlgear Assemblies – Part 2: Power Switchgear and Control Equipment Assemblies"

GB/T 15576-2020 "Low-Voltage Complete Reactive Power Compensation Devices"


Structural Features
Streamline classification, standardize criteria, dismantle the original cabinet type categories, unify the structure, and achieve seamless integration of cabinets.
Balancing differentiation, the design incorporates solutions for key components and cabinet layouts that have gained widespread adoption in recent years—and effectively point toward future industry trends. At the same time, to accommodate de-differentiated configurations, compact cabinet designs, SVG compensation, and communication interfaces are offered as optional features for users to choose from.
With appropriate foresight and a "one-step-ahead" approach, the design carefully anticipates future grid transformation needs by addressing key features such as the rated current series of switchgear, protection levels, reactive power compensation devices, emergency power interfaces, phase-checking systems, and feeder load monitoring. This ensures that once the equipment is operational, it will immediately meet all requirements, eliminating the need for frequent upgrades or overhauls down the road.
Simplifying operations and boosting efficiency, we’ve implemented unified and optimized designs for the switchgear’s structural layout, dimensional planning, insulation protection, and even the detailed installation methods of cabinet door hinges—making it easier for maintenance personnel to conduct inspections and perform operations, reducing the frequency of routine maintenance tasks, and ultimately enhancing overall work productivity.
