The global energy sector is undergoing a massive transformation toward decarbonization and grid modernization. In the Kingdom of Morocco, this transition is particularly ambitious. Under the visionary leadership of ONEE (Office National de l'Electricité et de l'Eau Potable), Morocco is positioning itself as a regional green energy hub, linking Africa to Europe via high-capacity interconnectors.
However, the geographical diversity of Morocco—spanning the humid, salt-heavy Mediterranean and Atlantic coastlines to the arid, sand-blown Sahara—presents unique challenges for electrical insulation. This is where Double-Shed Type Toughened Glass Insulators emerge as the critical technological standard.
The Double-Shed Type (also known as the two-wing or external shed profile) is engineered specifically for regions with heavy pollution loads. Unlike standard profiles, the double-shed design provides an increased creepage distance without significantly increasing the weight of the string. The elimination of traditional under-ribs in certain designs or the strategic addition of external wings allows for natural self-cleaning by wind and rain—a vital feature for the Moroccan 'Ghibli' wind seasons.
Morocco's Atlantic coast experiences high saline conductivity. Our Double-Shed insulators provide superior performance against salt-fog flashovers, reducing the need for frequent manual cleaning.
In the southern provinces, sand accumulation is the primary cause of leakage currents. The aerodynamic profile of our external shed glass insulators prevents dust buildup.
Near cities like Casablanca and Tangier, industrial pollution is prevalent. Our insulators meet the highest pollution class requirements (Class IV / Very Heavy) according to IEC 60815 standards.
Supporting the Noor Ouarzazate Solar Complex and wind farms in Tarfaya, our UHV-ready glass insulators ensure the stable evacuation of green energy into the national grid.
Founded in December 2002 with a registered capital of 508 million Yuan, QOCI is a global powerhouse in the manufacture of high-strength toughened glass insulators. Our facility, covering 70,000 m², is a testament to Chinese manufacturing excellence, now tailored for the Moroccan market.
Optimized for the Atlas Mountains and Rift Valley altitudes, where temperature swings and icing can occur.
Fully compatible with ONEE's 225kV and 400kV transmission networks, ensuring zero-defect performance.
High mechanical strength to withstand Morocco's high-wind zones in the Dakhla and Laayoune regions.
Supporting OCP Group phosphate mines and automotive manufacturing plants in Kenitra and Tangier.
The future of Morocco's grid is Smart and Sustainable. Our technical roadmap focuses on three pillars:
Due to the combination of coastal salt-fog and desert sand, Morocco requires insulators that do not trap pollutants. The double-shed design increases the "leakage distance / spacing" ratio, providing higher safety margins against pollution flashover without increasing the string length.
Yes, all our insulators are manufactured according to IEC 60305, IEC 60383, and IEC 60120 standards. We provide full type-test reports from independent laboratories (like KEMA or EGU) to ensure compliance with Morocco's national grid requirements.
Toughened glass is chemically inert and does not age like polymer insulators. In desert conditions, the expected service life exceeds 40 years, provided there is no severe mechanical damage.
We provide full-service logistics from our factory to the Port of Casablanca or Tangier Med, including all necessary certification and customs documentation for Moroccan importation.
