About us
CECI Power: 20 Years Behind the Lines That Light Up the World.
Founded in 2005, China Energy & Chemical Industry Co., Ltd. (CECI Power) is a vertically integrated OEM manufacturer of high voltage composite insulators, glass & ceramic insulators, and precision power line fittings.
Our 18,000 m² facility houses four dedicated production lines — silicone rubber injection, fiberglass core winding, glass tempering, and metal forging — supported by an in-house IEC-accredited testing laboratory.
Today, our products operate in transmission networks, substations, and railway systems across 50+ countries, including EPC projects in the Middle East, utility tenders in Southeast Asia, and railway electrification programs in East Africa.
We don’t just ship containers. We engineer long-term partnerships.

OEM & Project Supply
For OEM or project orders, provide the voltage level, mechanical load, creepage distance, overall length, end-fitting configuration, applicable standard, quantity and required documentation. A drawing or existing reference number is especially useful when a replacement or equivalent configuration is required.
We can use these requirements to determine the appropriate product configuration and prepare the technical and commercial information for review.
