PPC Insulators products

PPC offers the most comprehensive range of porcelain post insulators up to highest AC and DC system voltages with the most progressive technology, engineering and life time. Short production time, tighter tolerances, flexible design, extra-high mechanical strength and extended creepage distances are possible by isostatic process.

The latest industry trends and developments are reflecting increased concern and efforts for higher safety, better reliability and more control. PPC smart solution design is a well-proven solution for digital substations and smart grid integrated prognostics systems, which many of PPC customers have already adopted.

PPC Hybrid Line Post Insulators from 15 up to 35 kV combine the best of porcelain and silicone technologies: the ceramics high mechanical strength and the silicones excellent pollution performance under pollution. PPC Hybrid Line Post Insulators have an open profile allowing horizontal and vertical mounting.

With more than 90 years of experience in designing and manufacturing railway porcelain insulators, PPC has developed a new concept to improve safety and performance while optimizing cost considerations for our customers. Our research, in conjunction with national and transnational railway companies, yielded a high-grade design for C130 porcelain material with the optimum cement for assembly and fittings. The high-grade quality properties of this porcelain material allow a smaller core diameter, smaller sized fittings and make the insulator lighter than porcelain from other manufacturers.

PPC developed LD ceramic for electrostatic precipitator applications in the 1970’s in cooperation with ABB Svenska Flakt AB. LD ceramic was specifically engineered to provide high volume-resistivity in harsh high voltage DC environments. With it’s excellent volume resistivity and mechanical strength, LD ceramic is the perfect material for support insulators, feed through bushings, shaft insulators, and other specialized ESP insulator configurations.
