The electric-energy meter box is designed for centralized metering in apartment buildings, office blocks and household applications. It can be fitted with pulse-type energy meters as required by the design, enabling computer-based management and reserving space for tele-measurement and tele-signalling devices. Miniature circuit-breakers installed inside provide overload and short-circuit protection. All non-metallic materials, surface coatings on metallic parts, housing structural strength and marking are engineered for an expected service life of no less than 20 years.

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.
