Explore our high-performance electrical distribution configurations. Designed for rugged applications, outdoor environments, and modular system installations.
Hangzhou SN Electrical Co., Ltd. is a professional power distribution box manufacturer specializing in low-voltage electrical distribution systems, industrial power management equipment, and smart electrical solutions. Established in 2011, the company is located in Hangzhou, Zhejiang Province, China, benefiting from a strong industrial ecosystem and convenient international transportation networks.
With a manufacturing facility covering over 18,000 square meters and a workforce of more than 250 employees, SN Electrical integrates product design, sheet metal fabrication, assembly, testing, and quality control into a comprehensive production system. The company operates advanced manufacturing equipment and rigorous inspection procedures to ensure product reliability, safety, and compliance with international electrical standards.
Modern electrical infrastructure demands more than simple metal enclosures; it requires smart, safe, and communication-ready distribution channels. Hangzhou SN Electrical Co., Ltd. delivers high-value manufacturing solutions that bridge the gap between engineering innovation and cost-effective scalability.
Located in the heart of Zhejiang's manufacturing cluster, we draw from an unmatched raw material and component ecosystem. This proximity optimizes lead times for premium copper busbars, flame-retardant PC/ABS polymers, and advanced breaker components, ensuring rapid turnaround on high-volume runs without quality compromises.
We build systems aligned with strict global standards including IEC, CE, and IP ratings (ranging up to IP67). By combining advanced leak protection, lightning protection, and surge suppression, our systems provide long-term operational integrity and legal clearance across target markets.
Our OEM and ODM processes cater specifically to overseas partners, optimizing spatial dimensions, labeling requirements, and interface protocols for regional installations. Our team coordinates supply chain logistics for projects across Europe, the Americas, and APAC.
As the smart grid evolves, power distribution boxes must integrate with IoT sensors, remote monitoring devices, and green energy sources. Below is how our design adaptations support modern demands:
Our intelligent combiner boxes and AC/DC PV distribution boards are configured for solar (up to 16 in 1 out grid-connected) and battery storage installations, mitigating fluctuations and safeguarding equipment.
For industrial processing plants, coastal marine regions, and heavy infrastructure, our IP65 and IP67 weatherized polymer and cold-rolled steel enclosures resist dust, corrosion, and extreme temperatures.
By integrating micro-sensors, circuit indicators, and networked communication cards, we enable predictive maintenance and real-time power analytics for industrial facilities.
OEM and ODM Services: As a dedicated global partner, SN Electrical provides tailored engineering designs, component integration, private labeling, and custom enclosures suited for renewable energy arrays, commercial properties, and public utilities.
