Discover our primary range of engineered power distribution solutions designed for heavy-duty industrial environments, clean renewable energy integration, and smart automated factory grids.
Navigating the evolving landscape of global low-voltage distribution frameworks, industrial automation demand, and clean energy grid compliance.
Handling fluctuating DC load current generated by utility-scale solar farms and energy storage systems. Our high-voltage DC combiner cabinets provide reliable safety mechanisms for modern photovoltaic installations.
Integrating edge computing, smart metering, and Programmable Logic Controllers (PLCs) inside custom panels to enable real-time tracking of current, temperature, and environmental fluctuations.
Protecting fragile electrical switchgear, miniature circuit breakers (MCBs), and terminal blocks against dust ingress, water jet spray, extreme temperature variations, and aggressive chemical exposure.
A reliable engineering and manufacturing partner in high-quality power distribution and low-voltage electrical protection systems.
Established in 2011 and situated in the industrial hub of Hangzhou, Zhejiang Province, China, Hangzhou SN Electrical Co., Ltd. has grown to become a leading manufacturer in low-voltage electrical distribution systems, industrial power management equipment, and smart electrical solutions. Utilizing the region’s robust industrial supply chain and convenient access to international shipping ports, the company offers high-quality solutions to global clients.
SN Electrical operates a modern manufacturing facility covering over 18,000 square meters and employs a skilled workforce of more than 250 experienced professionals. Our comprehensive production process integrates in-house mechanical design, precision sheet metal fabrication, robotic welding, advanced powder coating, system assembly, and strict dielectric and testing controls.
Our extensive product portfolio features low-voltage power distribution boxes, industrial distribution panels, heavy-duty electrical enclosures, specialized meter boxes, modular control cabinets, IP65/IP66 waterproof boxes, outdoor electrical cabinets, and custom engineering-to-order configurations. We continuously invest in advanced manufacturing technologies, intelligent monitoring systems, and energy-efficient electrical solutions to meet the demanding requirements of industrial, commercial, infrastructure, and renewable energy projects worldwide.
Our engineering pathway ensures robust compliance with international testing regimes and adapts to the future of smart power grids.
We fabricate outdoor boxes up to IP66 levels (fully dust-tight and resistant to high-pressure water jets). Polyurethane foam-in-place gaskets applied via automated CNC machines provide reliable sealing performance over years of operation.
Available in premium cold-rolled steel, marine-grade 304 or 316 stainless steel, and high-impact polycarbonate. Metal versions are finished with epoxy polyester powder coating for high scratch and chemical resistance.
Our smart panels feature real-time current transformers, thermal monitoring sensors, RS485/Modbus communication links, and automatic circuit breaker status detection for predictive maintenance schemes.
Tailoring low-voltage protection systems to meet specific local building standards and environmental demands across the globe.
In Europe, standard installations require dedicated residual current protection (RCD Type B) and overcurrent safeguarding (MCBs) for electric vehicle charger boxes. Our Sh Series IP65 plastic modular DBs are designed to accommodate DIN-rail configurations, allowing easy integration of components that prevent DC fault currents from feeding back into the public grid.
Industrial settings in coastal regions or mining sites require enclosures that withstand salt spray, high humidity, and physical impacts. For these locations, we construct 304/316 stainless steel power distribution cabinets. These offer robust corrosion protection, and can be customized with dynamic solar shields, integrated ventilation louvers, and locks to prevent tampering in remote installations.
North American operations prioritize safe electrical service entry and switchgear compliance. Our custom low-voltage electrical switchgear enclosures (supporting current ratings up to 4000A) provide reliable performance for commercial facilities, data centers, and multi-tenant residential complexes.
Modern manufacturing plants rely on smart control panels to link factory floor sensors with centralized PLC boards. Our IP54/IP65 low-voltage control cabinets are built with clean cable management channels, transparent polycarbonate viewing windows, and integrated active cooling systems to maintain safe operation for critical controls.
Our comprehensive quality control systems and tailored manufacturing capabilities support projects throughout Europe, the Americas, the Middle East, and Asia.
We design structural dimensions, cable entry configurations, mounting brackets, and door hinges to fit your specific physical installations.
We install switchgear, MCBs, MCCBs, SPDs, contactors, and control components from leading brands or based on customer-specified requirements.
We offer customized branding, laser-engraved labels, unique color coatings, and packaging styles to align with local market requirements.
Engineered to handle high current demands and provide reliable protection for commercial buildings, factories, and utility installations.
