Tailored electrical protection components for Sihanoukville and Phnom Penh Special Economic Zones.
As Cambodia transitions from a primarily agricultural economy to an industrial powerhouse, the stability of its electrical grid has become paramount. With the rapid expansion of the Garment, Footwear, and Travel Goods (GFT) sectors, and the massive growth in the Sihanoukville Special Economic Zone (SSEZ), the demand for reliable circuit protection has never been higher.
Wenzhou Shuguang Fuse Co., Ltd. recognizes the unique challenges faced by Cambodia’s power sector, including tropical humidity, varying voltage stability in rural areas, and the necessity for rugged, IEC-compliant hardware that can withstand heavy industrial cycles. We provide comprehensive solutions that align with EDC (Electricite du Cambodge) standards, ensuring that local factories and commercial hubs maintain uptime even under demanding conditions.
Wenzhou Shuguang Fuse Co., Ltd. is strategically located in Yueqing, Zhejiang Province—the globally recognized "Electrical Capital of China." We are a power technology enterprise integrating research, development, production, sales, and service. Our legacy dates back to 1992, established as the "Yueqing Shuguang Fuse Factory."
For over 30 years, we have specialized in the manufacturing of high-voltage and low-voltage fuses that meet the most stringent international criteria. Our commitment to Information Gain in the SEO landscape is mirrored by our commitment to Technical Gain in the factory. We don't just supply fuses; we provide engineering data and safety assurances that protect multi-million dollar investments in the Cambodian energy grid.
30+ Years Experience
Exporting to 50+ Countries
ISO9001:2000 & IEC
Meeting EDC and International standards for maximum safety and reliability.
Our products are designated by the Ministry of Electric Power Industry to produce high-voltage fuses of various voltage levels, current-limiting fuses, and zinc oxide arresters. The highest technical performance of Shuguang products meets:
All products have passed the high-power test station of the Electric Power Research Institute and the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center.
Cambodia's "Power Development Plan (2022-2040)" emphasizes renewable energy and grid reliability. Our RT18 series and HRC fuses are essential for the integration of solar farms in Kampong Chhnang and the protection of transformer stations across the Mekong region.
As Cambodia embraces green energy, the need for specialized DC fuses grows. We are expanding our technology roadmap to include high-voltage DC fuses specifically designed for PV inverters and EV charging piles, ensuring low power loss and high breaking capacity.
Modern factories in the Phnom Penh area require fuses with precise "Time-Current" characteristics. Our current-limiting fuses prevent catastrophic damage to expensive PLC and motor systems by interrupting faults in milliseconds.
We are investing in "Smart Fuse" technology—incorporating micro-sensors to monitor fuse health in real-time. This aligns with Cambodia's Industry 4.0 goals, reducing manual inspections in remote substation locations.
Reliable LV fuses for skyscraper distribution panels and HVAC systems.
Medium voltage solutions for heavy manufacturing and shipping ports.
Tail tail wire recovery and capacitor protection for renewable sites.
Drop-out fuse cut-outs for reliable power delivery to rural provinces.
Expert answers for Cambodian procurement managers and electrical engineers.
Typically, standard low-voltage fuses are shipped within 7-15 days. For custom high-voltage orders, our manufacturing cycle is 20-30 days, with direct sea freight to Sihanoukville Autonomous Port (PAS) taking approximately 10-14 days from Ningbo or Shanghai.
Yes. Our fuses meet IEC 60282 and IEC 60644 standards, which are the primary reference for EDC's technical specifications. We provide complete testing reports from the National High-voltage Electrical Apparatus Quality Supervision and Inspection Center to facilitate project approval.
We use high-grade porcelain and corrosion-resistant silver-plated copper for all contact points. Our "Tropicalized" range features additional environmental sealing to prevent oxidation and ensure stable resistance over years of service.
Absolutely. As a direct manufacturer, we can adjust the current-limiting characteristics, physical dimensions, and mounting styles to match legacy equipment often found in older Cambodian substations or modern European-standard industrial parks.
