Namibia represents one of the most demanding environmental and electrical landscapes in Southern Africa. Blessed with some of the highest solar irradiance levels globally, the country has seen an exponential rise in utility-scale photovoltaic installations and distributed solar mini-grids. However, this high solar yield is accompanied by intense lightning flash densities in the northern and central highlands (such as the Khomas Hochland plateau), alongside extreme dry soil resistivity that severely challenges traditional grounding solutions.
As a leading supplier and manufacturer of Surge Protective Devices (SPDs), we specialize in mitigating these dual hazards. When earth resistance is high, lightning strikes cause massive earth potential rise (EPR), pushing transient currents directly back into critical equipment. Our surge lightning arresters are specifically engineered with heavy-duty Metal Oxide Varistors (MOVs) and Gas Discharge Tubes (GDTs) to safeguard Namibian investments against these destructive atmospheric events.
Our solutions conform directly to SANS/IEC 61643 standards, matching the strict electrical code mandates enforced by the local utility NamPower and municipal distributors. Our products offer optimized voltage protection levels (Up) and massive nominal discharge currents (In) to handle both direct and indirect atmospheric discharges.
Heavy industrial infrastructure and solar grids require robust transient voltage suppression (TVSS) systems.
High-performance surge arresters selected for immediate deployment in solar farms, commercial power cabinets, and mining infrastructure.
Designed specifically for residential and light commercial solar installations operating up to 500VDC. Offers robust transient overvoltage suppression for inverter input protection.

At Shuorui Electric, quality control is central to our manufacturing process. We maintain strict quality standards from raw material inspection (including incoming varistor block testing) to final product testing.
Our testing facilities include advanced impulse generators capable of simulating direct and indirect lightning strikes (up to 100kA 8/20µs waves). This guarantees that every SPD delivered to our customers in Namibia and globally meets international performance standards.
Our extensive product line covers the entire range of electrical protection needs. From miniature circuit breakers (MCB) and molded case circuit breakers (MCCB) to PV DC switches, AC contactors, and specialized SPDs, we provide complete, integrated protection solutions.
This allows engineering firms and distributors to source complete protection setups from a single, reliable manufacturer, simplifying logistics and ensuring system compatibility.
We offer extensive OEM and ODM services to adapt our products to specific local requirements. Whether you need custom voltage thresholds, specialized branding, integrated remote signal contacts, or unique housing designs, our R&D team can deliver.
We work closely with local partners in Namibia to optimize products for high-altitude solar farms and coastal marine environments like Walvis Bay.
All manufacturing processes are managed under ISO 9001 quality management systems. Our SPDs carry key certifications including CE, TUV, and IEC compliance. These certifications verify that our surge protectors are fully compliant with international safety codes, providing peace of mind for engineering teams in Namibia.
How our surge protectors address specific environmental challenges across Namibia.
Namibia's high solar irradiance is ideal for solar generation, but the long DC lines act as antennas for electromagnetic induction from lightning strikes. Our 1000VDC and 1500VDC Type 2 SPDs protect inverter input boards, preventing downtime and equipment damage in solar installations across the country.
Mining operations require highly reliable electrical systems. Heavy machinery and automated control loops are sensitive to voltage transients. Our robust 3-pole SPDs and low-voltage DC protectors (24VDC/150VDC) help prevent operational interruptions and protect sensitive electronics in mining operations.
Remote telecom installations are highly vulnerable to direct and indirect lightning strikes. Using our reliable 1P/2P AC SPDs and DC surge protection systems, network operators can ensure continuous operation and minimize maintenance site visits in remote areas.
