As the economic heart of Indonesia, Jakarta faces unique challenges in power transmission. The rapid urbanization, combined with high humidity, tropical rainfall, and coastal salt spray, necessitates a shift from standard insulators to Double-Shed (External Shed) Type Glass Insulators. This technology is not merely an upgrade; it is a fundamental requirement for the resilience of the Jakarta-Bandung high-speed rail corridor and the expanding industrial zones in Bekasi and Tangerang.
The "Double-Shed" design is engineered to double the creepage distance compared to standard profiles while maintaining a compact vertical footprint. In the context of Semantic Search and modern electrical engineering, these products represent the intersection of material science and aerodynamic optimization.
Jakarta’s monsoon seasons cause frequent "pollution flashovers" on standard insulators. Double-shed types utilize an aerodynamic profile that encourages self-cleaning via rain and wind, critical for the Jabodetabek power ring.
Serving the heavy industries in Cikarang, our U-series insulators provide the mechanical strength (up to 300kN) required for extra-high voltage (EHV) lines crossing industrial parks.
Coastal areas like North Jakarta (Tanjung Priok) suffer from saline accumulation. Our external shed profile prevents conductive film formation, ensuring zero leakage current.
Optimized for use with RTV silicone coatings, our toughened glass insulators are the backbone of the "Next-Gen" digital power grid being pioneered by PLN (Perusahaan Listrik Negara).
Founded in 2002 with a registered capital of 508 million Yuan, Jiangxi QOCI Electric Co. Ltd stands as a titan in the global glass insulator market.

Our facility utilizes Total Oxygen Kilns and Automatic Forming Presses to ensure that every disc meets the stringent IEC 60305 standards. For Jakarta's procurement managers, this means a reliable supply chain with Zero-Defect quality assurance.
Specifically designed for North Jakarta's high-salinity environment, preventing salt-fog flashover.
Supporting the backbone transmission lines that link Jakarta's grid to regional power sources.
Compact double-shed designs allow for higher creepage in the restricted spaces of Central Jakarta.
High-strength glass insulators for Bekasi's manufacturing zones, resistant to chemical pollution.
As we look toward 2030, the Double-Shed Type Glass Insulator will evolve. QOCI Electric is currently developing "Smart Insulators" integrated with IoT sensors to monitor leakage current in real-time. This aligns with Indonesia's "Making Indonesia 4.0" initiative. Our current manufacturing precision ensures that we provide Information Gain to our clients—giving them data-backed assurance that their grid will not fail under the increasing pressure of climate change.
Our commitment to "Innovation, Quality, and Service" has enabled us to participate in world-class power grid constructions. We specialize in:
