Sowest Electric
Industrial grade Automatic Transfer Switches tailored to maintain zero-downtime operations for critical agricultural and municipal systems.
As the administrative capital of the Gorgol Region in southern Mauritania, Kaédi serves as a vital economic hub located along the Senegal River. Characterized by agriculture, trade, and regional healthcare services, the local economy relies heavily on consistent electrical grid connectivity. However, the municipal power supply faces persistent challenges typical of sub-Saharan regional hubs—including voltage instability, periodic transmission deficits, and heavy reliance on local diesel generation during peak agricultural seasons.
To overcome these challenges, Kaédi’s processing plants, agricultural co-operatives, commercial centers, and healthcare facilities are transitioning toward hybrid power architectures. By integrating the national utility line with diesel generator reserves and modern solar photovoltaic array configurations, operators can guarantee operational continuity. At the heart of this grid architecture lies the Automatic Transfer Switch (ATS).
Deploying energy equipment in the Kaédi market demands strict consideration for environmental factors. High ambient temperatures, seasonal dust storms (harmattan winds), and voltage spikes require resilient switches. The selection between PC-Class and CB-Class ATS is crucial for system durability.
| Parameter | PC-Class ATS (Double Throw Structure) | CB-Class ATS (Circuit Breaker Based) |
|---|---|---|
| Overcurrent Protection | Requires external fuse or thermal-magnetic circuit breaker. | Integrated overcurrent trip releases. Works as protection + switch. |
| Mechanical Endurance | Extremely high (>10,000 cycles). Built strictly for electrical transfer. | Moderate. Circuit breaker linkages have higher mechanical complexity. |
| Withstand Rating (WCR) | Very High. Capable of surviving heavy short circuits without damage. | Limited to the breaking capacity of the integrated circuit breakers. |
| Ideal Application in Kaédi | Critical loads, backup generators, heavy water pumps, processing mills. | Sub-distribution boards, commercial lighting, light workshops. |
Designed to switch seamlessly between solar inverter output, utility grid lines, and auxiliary diesel backup based on battery bank thresholds.
Constructed with high-durability thermal plastic compounds and silver alloy contacts to operate efficiently in temperatures exceeding 45°C without derating issues.
Designed with tight-fitting structural framing to isolate switching relays from atmospheric dust particles, safeguarding long-term dielectric performance.
Zhejiang Sowest Electric Co., Ltd. is a modern, innovative enterprise specializing in the research, development, manufacturing, and global sales of premium power supply and electrical distribution equipment. As an established developer of transfer switches, we support the Kaédi market by providing high-quality, engineered products built to survive demanding regional environments.
Our comprehensive production facility leverages advanced laser cutters, automated shearing machines, precision tapping lines, and automatic dispensing machines. We ensure that every ATS shipped to West Africa meets the highest international certifications (such as IEC 60947-6-1 and CE standards) and performs reliably under heavy load cycles. Guided by the principles of integrity, innovation, and mutual growth, Sowest Electric is your ideal engineering and sourcing partner.
Purchasing electrical switches for West African locations requires streamlined supply chain transparency and reliable delivery channels. Sowest Electric provides end-to-end support for regional distributors, engineering firms, and municipal procurement agents in Mauritania.
Our technical team coordinates directly with your engineers to design custom transfer switches that align with local project specifications. We support custom current capacities ranging from 16A up to 3200A, offering both DIN-rail mounted options for localized boxes and integrated heavy-duty switches for main distribution panels.
By leveraging partnerships with major shipping lanes and regional ports, including the Port of Nouakchott, we ensure safe and efficient shipping to Mauritania. We provide complete documentation support (CO, bill of lading, export certifications) to facilitate straightforward customs clearance and direct inland freight routing to Kaédi.
Our commitment to your project extends beyond delivery. We offer comprehensive wiring documentation, circuit diagrams, and remote commissioning assistance. This support makes it easy for local technicians in the Gorgol region to install, calibrate, and service our equipment.

Modern electrical infrastructure is advancing beyond simple physical switches. In the next generation of industrial installations across Gorgol, operators are integrating smart telemetry and communication modules to monitor system performance remotely. Zhejiang Sowest Electric Co., Ltd. is actively designing smart modules to enable predictive maintenance and monitoring.
Our newer generation switches feature integrated RS485 communication ports using Modbus RTU protocols. This allows municipal operators or industrial facilities in Kaédi to monitor real-time phase currents, voltage levels, frequency deviation, and mechanical life metrics from centralized control rooms.
By using contact temperature detection and cycle counters, our intelligent controllers can alert system engineers before contact degradation occurs. This helps prevent unexpected system failures and optimizes maintenance schedules.
With the rise of local solar-diesel hybrid projects in Mauritania, our smart switches can coordinate with battery energy storage systems (BESS). They manage switching thresholds intelligently to maximize renewable usage and reduce reliance on diesel generators.
PC-class ATS uses a double-throw structure powered by electromagnetic coils. It acts strictly as a transfer switch and lacks integrated overcurrent protection. It features a higher short-circuit withstand rating and long mechanical life. CB-class ATS is equipped with an overcurrent release mechanism. It acts as both a changeover switch and a circuit breaker, making it a compact option for sub-distribution boards.
Sowest switches are designed with high-grade, heat-resistant polymers and silver alloy contact tips. For installations where temperatures consistently exceed 40°C, we advise cross-referencing our temperature derating coefficient charts. This ensures you size the switch correctly for continuous load requirements in hot climates.
Yes. Our range of single-phase and three-phase transfer switches are widely used in solar-generator hybrids. They are designed to manage transitions between the inverter AC output, backup generator power, and the main grid utility efficiently.
All transfer switch gear manufactured by Sowest Electric conforms to IEC 60947-6-1 standards (the global benchmark for automatic transfer switching equipment). They also comply with CE regulations, guaranteeing compliance for projects requiring strict quality standards.
Depending on order volume and customization requirements, standard production takes 15 to 25 days. Ocean shipping to the Port of Nouakchott averages 30 to 40 days, followed by land transport to Gorgol or Kaédi.
