Discover our high-reliability, standard-compliant Air-Insulated Switchgear engineered to operate seamlessly under challenging electrical conditions, ensuring stable power delivery across Mozambique’s utility networks.
Mozambique is undergoing massive macroeconomic changes. Propelled by massive offshore natural gas findings in the Rovuma Basin (Cabo Delgado), coal mining in Tete, and expansion projects in the Port of Beira and Nacala Corridor, industrial demand for electricity is growing exponentially. The national electricity utility, Electricidade de Moçambique (EDM), is rapidly driving rural and industrial electrification schemes to achieve universal access by 2030.
However, this fast growth brings unique system challenges. Much of the power transmission grid operates across massive distances, requiring robust medium-voltage (MV) and high-voltage (HV) networks. In regions like Maputo, Beira, and Quelimane, the coastal tropical climate introduces extreme relative humidity (often exceeding 85%) and airborne salt spray, which can accelerate the degradation of substation insulation. In the dry, hot interior regions of Tete, ambient temperatures often soar past 40°C, testing the thermal limits of electrical switchgear.
In this climate, traditional switchgear often suffers from premature degradation, insulation tracking, and overheating. Reliable Air-Insulated Switchgear (AIS) engineered with high-grade copper busbars, creepage distance enhancements, and anti-corrosive structural elements is absolutely critical to guarantee uninterrupted operations for mining, port handling, and municipal distribution networks.

In step with global sustainability goals, Zeno Electric provides dry-air insulated RMUs and switchgears. These designs eliminate SF6 greenhouse gas risks entirely, helping mining and infrastructure companies reduce environmental compliance overhead.
Equipped with state-of-the-art microprocessors, digital protection relays, and support for IEC 61850 protocol communications, our switchgear systems easily integrate into SCADA systems monitored by central EDM substations.
Deploying switchgear in Sub-Saharan Africa, particularly in the Southern African Development Community (SADC) region, requires attention to detail regarding local utility guidelines and technical practices. Mozambique’s grid runs at 50Hz, utilizing primary medium voltage distribution levels of 11kV, 22kV, and 33kV. For instance, rural substations connecting agricultural and irrigation loads rely heavily on 33kV/400V setups. Heavy industries, such as coal extraction in Moatize (Tete Province) and aluminium smelting in Beluluane, utilize large 11kV or 22kV local distribution networks.
While Gas-Insulated Switchgear (GIS) offers high compactness, Air-Insulated Switchgear (AIS) remains the practical choice for most of Mozambique’s open-air primary and secondary substations. The primary reason is maintainability. In the event of a fault, local utility engineers can inspect, troubleshoot, and repair AIS units manually with readily available copper links, insulators, and replacement circuit breakers. GIS setups, conversely, require highly specialized SF6 gas handling machinery and certified technicians—resources that are often difficult and costly to mobilize to remote mining fields in northern provinces like Niassa or Cabo Delgado.

Procuring heavy-duty electric assets directly from our state-of-the-art facility in Ningbo offers key project execution benefits for Mozambican power developers, EPC contractors, and regional utilities:
By utilizing streamlined component sourcing, high-volume automated manufacturing, and a skilled technical workforce in Ningbo, we offer switchgear panels at an optimized Capex point, allowing local Mozambican contractors to stay within budget constraints without sacrificing safety or performance.
Unlike rigid Western OEM suppliers, we offer responsive engineering flexibility. Whether your project requires custom panel sizing for small substations, tropicalized auxiliary wiring, customized protection settings, or specific ingress protection configurations (IP54), our Ningbo engineers can build to order.
Ningbo is home to one of the largest deep-water cargo shipping hubs in the world. We coordinate direct sea routes from the Port of Ningbo-Zhoushan straight to Mozambique's critical trade gateways: the Port of Maputo for southern grids, the Port of Beira for central operations, and the Port of Nacala for northern projects.

Our standard manufacturing lead time is approximately 4 to 6 weeks, depending on order size and complexity. Shipping from the Port of Ningbo to Beira, Nacala, or Maputo takes around 25 to 35 days, bringing the total time from order confirmation to port arrival to roughly 8 to 10 weeks.
Yes. All of our switchgear designs are built, tested, and certified in accordance with standard IEC 62271-200, which EDM references for medium voltage indoor switchgear. We provide complete type test sheets from ASTA / ILAC-accredited laboratories to verify this compliance.
For coastal locations in Mozambique, we apply specialized anti-corrosion finishes (such as C4 or C5 class powder coatings). Additionally, we implement copper busbars fully encapsulated in heat-shrinkable epoxy insulation, and install integrated anti-condensation heaters managed by temperature and humidity controllers within each cabinet.
Yes. We offer SF6-free solid-insulated and dry-air insulated Ring Main Units (RMU). These models use vacuum interrupters and pressurized clean dry air as an insulating medium, eliminating greenhouse gases and simplifying end-of-life disposal.
Absolutely. While our manufacturing is based in Ningbo, we offer remote video support, comprehensive installation guidelines, and on-site commissioning services. We can dispatch certified electrical field service engineers to work with local Mozambican contractors during installation, cable termination, and initial grid-tie testing.
