15kV American Type Elbow Surge Arrester
Range of Application
Apply to American switch equipment for voltage of 8.7/15kV, avoid equipment and element damage of electric system power transmission equipment caused by lighting overvoltage and switching overvoltage.
Product description
Product adopts EPDM material to produce, which with excellent aging resistance, electrical insulation property, corona resistance, ozone resistance and good chemical stability, can be operated under any working conditions.
Each batch of raw material takes the mechanical properties and electrical properties index testing, which ensures product quality from source.
All finished products 100% takes the factory performance test (power frequency withstand voltage, partial discharge)
Import DESMA liquid injection production system, with dustless and air-conditioned manufacturing shop, and constant temperature and humidity all year round, which ensures the product not affected by external environment and the quality stability of product
Product structure design complies with 600A bushing size requirement of IEEE386 standard, and meet the performance requirement of IEC60099,GB11032 standard, which is safe and reliable with long period operation.
With professional engineering installing team, and years of installation and operating experience, providing the field installation and guide installation, we can make sure the finished product installation quality.
Technical Feature
Product adopted high-performance zinc oxide core of resistor disc, which with excellent nonlinear current-voltage characteristics ,good respond of steep wave, excellent through-current capability and other good characteristic to ensure power network line operated safely.
