In the event of an internal fault/ inner over pressure or external influence/ vandalism a porcelain insulator will show a violent failure (explosion) with dangerous fragments dashed around at high speed. The failure mode of a composite insulator is delamination/ puncture without launching of destructive fragments. There is no damage of surrounding equipment and no danger for persons in the vicinity. This gives maximum safety for both personnel and substation. ABB produces hollow composite insulators by extruding silicone rubber sheds on to a composite tube using a patented helical extrusion process. These well-established manufacturing practices and improved material properties ensure reliable service over the life of ones electrical apparatus. ABB Composite Insulators with silicone rubber sheds offer many advantages over traditional ceramics: •Improved safety for personnel and equipment •Superior pollution performance due to hydrophobic surface condition •Excellent seismic performance •Low weight •Short delivery times •Flexible design ABB Composite Insulators are normally used in: •Circuit Breakers •Bushings •Instrument Transformers •Cable Terminations ABB is currently providing hollow composite insulators in the voltage range 72 kV 800 kV and in lengths up to 10m. All composite insulators are tested and certified according to IEC 61462.

Product DescriptionFor many years, race cars of all types have been constructed with lightweight materials other than aluminum or steel. The application of this space-age technology is also becoming more widely used on street cars as stronger materials are developed, costs become lower, and techniques are simplified. This book is a comprehensive technical handbook on the most current technology behind fiberglass and other composite materials. . . . More >>
