Advantages of the polymer housed surge arresters:
Sediver has more than 30 years experience in composite insulator technology in direct injection molding of the polymer
housing under high pressure and high temperature. This technology is applied to our surge arresters out of which we
obtain:
Increased life time of the ZnO blocks which are protected from moisture ingress
thanks to our impenetrable design
Excellent mechanical characteristics due to the fiber glass reinforced polymer tube
Excellent pollution performance of the silicone housing
Excellent protection performance due to very stringent selection of extra high
quality, high energy duty metal oxide blocks
Increased safety of surrounding crew and equipment thanks to the explosion proof
design (air-free)
Easy to install and transport due to the low weight
Reduced space requirements thanks to its compact design
Norway 300 kV line
Selection:
Through expertise conducted using simulation software tools, our experts are able to determine optimal arresters types
& location to protect the key points of the system, thus providing effective protection at the lowest cost.
