Shatter test has been performed on live tank circuit breakers to compare the failure mode of pressurized porcelain and composite insulators. 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. More and more utilities now only specify use of composite insulators on the substation equipment for the reason of safety for personnel working in the substations.
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 and flexible design.
ABB Composite Insulators are normally used in: Circuit breakers, bushings, instrument transformers and cable terminations. ABB is currently providing hollow composite insulators in the voltage range from 72 kV – 1100 kV AC / 800 kV DC and in lengths up to 11 m. All composite insulators are tested and certified according to IEC 61462.
