Description
General
Detachable type surge arrester is an optimized distribution type zinc oxide arrester and to mount on a drop out (explosive) fuse cutout on the pole. It is applicable to operate with insulating hot stick. It is easy for detection, repair and replacement which not only assure the stability of distribution line, but also greatly reduce maintenance needed. It is particularly applicable to
locations where requires continuous power supply like telecommunication station, airport, hospital, commercial center. The properties are same with distribution type surge arrester.
Advanced RW-12 type drop out mechanism, reliable contact, and composite support are applied to this type of surge arrester. It has features of good anti-pollution, quick operation, wide current range, and high withstand capacity to current impulse and operating load.
This type of surge arrester meets standardIEC60099-4:1991.
Characteristic
1. Lightning arrester unit can be charged at any time,particularly suitable for loading and unloading place should not be cut.
2. Belt disengaging device,arrester unit fault can automatically turn fall, out of the operation,safeguard the normal traffic line.
3. Because the failure unit falling formmarked, easy to find, to repair and replace.
4. Lightning arrester using composite coat, drop mechanism adopts a composite column, good gydrophobicity, stain resistant ability.
