SH Power possesses a well-established R&D and engineering team capable of tailoring exclusive solutions for various project requirements. From system design to on-site application, we provide comprehensive technical support, helping customers achieve safe, intelligent, and highly efficient power distribution systems.
In today’s fiercely competitive market, the MNS modular low-voltage switchgear, backed by decades of proven service, has set the mainstream course for switchboard development. The entire system reserves ample room for future expansion, while its advanced technology maintains a clear, forward-looking lead in the field. The basic skeleton of an MNS cubicle is built from standardized C-section profiles on a 25 mm modular grid (the C-section mounting-hole pitch). Without special tools this framework can be assembled into any cabinet configuration—front-operated or back-to-back, single or multiple-tier arrangements.

Features & Advantages
Our switchgear, including C-GIS and ring main units, features a compact and modular design, saving valuable installation space and allowing for flexible expansion and easy on-site assembly.
With all high-voltage components sealed in a stainless-steel gas tank, our equipment is protected from environmental factors. It features reliable mechanical and electrical interlocks to ensure the safety of operators.
Committed to sustainability, we offer eco-friendly switchgear that uses dry air as the insulating medium, completely eliminating SF₆ gas and minimizing environmental impact.
The fully sealed and insulated design ensures our switchgear is virtually maintenance-free throughout its service life, significantly reducing operational costs and downtime.
Our products can be integrated with intelligent solutions, supporting remote monitoring, control, and automated distribution systems, which is crucial for building modern smart grids.
Ideal for secondary distribution substations, industrial parks, commercial buildings, and residential communities, providing reliable power control and protection.
Perfectly suited for renewable energy applications such as wind farms and solar power plants, where compact and reliable switchgear is essential for power collection and grid connection.
Deployed in critical infrastructure like subways, railways, airports, and tunnels, where space is limited and high reliability is non-negotiable.
Used in demanding environments such as mining, petrochemical plants, and data centers that require robust, safe, and uninterrupted power management.
