Nigeria, as the largest economy in Africa, is currently undergoing a massive transformation of its energy sector under the Presidential Power Initiative (PPI). The Transmission Company of Nigeria (TCN) and various Distribution Companies (DisCos) are prioritizing the modernization of aging lines. However, Nigeria's unique geography—ranging from the high-humidity, salt-laden coastal air of Lagos and Port Harcourt to the dust-intensive Harmattan regions in the North—presents significant challenges for traditional insulators.
Our Double-Shed Type Glass Insulators are specifically engineered to provide an increased creepage distance, which is critical for preventing "Pollution Flashover" in these high-stress environments. Unlike standard profiles, the double-shed design allows for superior self-cleaning during Nigeria's heavy seasonal rainfalls, ensuring grid stability and reducing maintenance cycles for industrial hubs in Ogun State and the Federal Capital Territory.
With 53+ specialized engineering technicians, Jiangxi QOCI Electric Co. Ltd integrates decades of material science research into every insulator produced.
Located in the world-renowned insulator hub of Pingxiang, our facility produces 39,000 tons annually, serving global power grids with IEC 60305 compliance.
Registered capital of 508 million Yuan and 26+ national patents ensure that our partners in Nigeria receive consistent, high-quality manufacturing support.

Coastal cities face severe saline corrosion. Our RTV Silicone Coated and Double-Shed Glass insulators offer hydrophobic properties that repel moisture and salt deposits, drastically reducing "leakage current" that causes frequent outages in the Eko and Ikeja DisCo networks.
The Sahel region faces dust accumulation. The aerodynamic profile of our Double-Shed insulators prevents dust build-up, utilizing the wind for natural self-cleaning, essential for the TCN's Northern backbone expansion.
Industrial pollutants can bridge standard insulator ribs. Our Triple-Shed and Double-Shed designs provide the necessary "open profile" to prevent arc-bridging in high-pollution manufacturing corridors.
Supporting Nigeria's 330kV and upcoming higher voltage super-grids. Our products undergo rigorous High Voltage testing to ensure zero failure rates under extreme mechanical loads.
Optimized for Tropical Climates
TCN & DisCo Approved Standards
High Mechanical Reliability
Fully Compliant with SON (Standards Organisation of Nigeria) & NEMSA Requirements.
As the global energy landscape shifts toward decentralized renewables, our research facility is currently developing Smart Insulators equipped with leakage current sensors for real-time grid monitoring. For the Nigerian market, we are focusing on:
The double-shed design increases the creepage distance compared to standard types. In coastal environments, salt fog creates a conductive layer on insulators. The extended shed prevents this layer from bridging, significantly reducing pollution flashovers.
Yes, all our glass insulators are manufactured strictly under IEC 60305, IEC 60383, and IEC 60120 standards, which are the benchmarks used by the Transmission Company of Nigeria (TCN) and NEMSA.
With an annual output of 39,000 tons, we maintain a robust stock of standard U70 and U120 models. Production for custom large orders typically takes 4-6 weeks, with direct shipping to Apapa or Onne ports.
Our engineering team can assist in selecting the correct profile (Standard, Anti-pollution, or Double-shed) based on your project's specific pollution level and mechanical load requirements.
