Drop out surge arrester

The drop out lightning arrester is the distribution type zinc oxide lightning arrester modified cleverly installed on the drop type structure of the drop out fuse cutout, to achieve in the case of continuous power, can be easily detected, repaired and replaced by the insulation brake and rod, not only to ensure the smooth line, but also greatly reduce the power maintenance personnel’s work intensity and time. Especially suitable for places that are not suitable for power outage, such as posts and telecommunications, airport stations, hospitals, bustling business districts, etc. The other performance of the product is the same as the distribution type arrester. The second generation of drop type lightning arrester adds a disconnector, when the lightning arrester is abnormal, the use of power frequency short-circuit current to make the disconnector action, the disconnector ground terminal automatically disconnects, the lightning arrester component overturns, exits the operation to prevent further expansion of the accident, and easy to maintenance personnel timely discovery of repair and replacement, the overturning principle is similar to the fuse caused by the melting tube overturns.

Our company adopts the world’s most advanced RW12 drop out fuse cutout mechanism, reliable contact, flexible closing, and the use of composite pillar stainless steel cover advanced accessories, with anti-fouling, fast action, wide current range, and withstand the specified current impact and action load advantages. Product performance meets the national standard GB11032-2010(eqVIEC60099-4:2009) “AC gapless metal oxide arrester”, JB/T8952-2005 “AC system with composite gapless metal oxide arrester”, Gb31.1-1997 “Insulation coordination of high-voltage power transmission and transformation equipment”.
