Energy Division PCA Single Column Polymeric Surge Arrester
Bowthorpe EMP pioneered the development of the polymeric composite housed surge arrester in the early 1980 s and since 1986 has a proven service experience across the globe, operating in the world s toughest environments. Bowthorpe surge arresters provide active over-voltage protection that contributes directly to improved reliability of your system, reducing system outages and protecting expensive terminal equipment. Bowthorpe PCA silicone surge arresters have been designed and tested to meet our customers demands with reliability and offering optimum operational performance. The Bowthorpe EMP arrester is made possible by: Proven moisture sealing technology. Non-tracking insulating silicone materials. Fully integrated single piece and void less design. Safe mode of failure. Quality. The PCA series arrester is designed to perform in the toughest environmental conditions and to meet and exceed the requirements of IEC60099-4. Our gapless zinc oxide polymeric arresters have been in service since 1986 and now the PCA range builds on that experience and know how. The PCA development has been based on 30 years of internal experience in arrester design and manufacture within the Tyco Electronics Energy Division. The PCA qualification was performed in internationally recognised and independent laboratory facilities in Europe. Sealing: All arrester cores are encapsulated in silicone insulating housing. A permanent chemical bond connects arrester core and the non-tracking silicone housing. This invisible interface prevents moisture from entering during severe thermal fluctuations due to normal climatic and energy absorption events. The arrester void-free construction eliminates moisture vapour transmission. Polymer housing: Non-tracking and hydrophobic silicone insulating material is used for PCA arrester housings. The PCA series is available with standard or extended creepage distance. The housing material has a proven performance in long term TERT and UV aging tests and a proven resistance to flammability. Integrated design: Manufacturing integrates all components in a single piece. There are no glued interfaces. The design is void and gap free ensuring optimum performance under the harshest conditions. Safe mode of failure: Safe mode of failure in the event of short circuit. Quality: Manufactures in Quality ISO accredited operations 2
