TCI Group

Dalian Composite Insulator Co.,Limited (DCI), a subsidiary of TCI, specializes in composite insulators of all kinds for high-voltage applications and related products. Main products include composite insulators for electric power lines from 10 to 800kV, composite insulators for electric railways, phase spacers, disconnecting switches, bushings, sur... ge arrestors, etc. Our products have a good reputation in international markets. Our Factory is well equipped with all worldclass facilities, such as programmable tensile load testers, crimping systems with acoustic emission detectors, fully automated rubber injection moulding machines, vulcanization testers, a complete set of power frequency transformers and impulse voltage generators. Our annual production capacity of composite insulators is 500,000. Our own designed and manufactured anti-pollution type composite post insulator with porcelain core composite consists of a porcelain core, sheds and metal fittings. The inner insulation is made of high-strength porcelain by isostatic pressing processing technology,can bear the whole mechanical load in the running. The shed is made of composite material and the raw material is silicone rubber by the high-temperature injection technology, it has provided insulation and necessary creepage distance, to ensure the composite post insulator running long-term and safety in the atmosphere environment. When the porcelain insulator breaks due to the brittleness, the wrapping to porcelain core by shed can reduce the harmful influence to the workers at working site and other electrical equipments around. Our composite insulator products passed the tracking and erosion test at CESI Mannheim, Germany in 2010. We implemented the ISO 9001:2008 Quality Control and the ISO14001:2004 environmental management systems. DCI's management and comprehensiv ecompetitiveness, quality of products and services, benefited enormously. DCI's products have been exported to Europe, America, Oceania, Africa and Asia. In the Middle East, DCI has taken a ...Read More
