Oil Insulated Automatic Section Switch |
|
| The oil insulated automatic section switch is a switchgear that can give the opportunity for transient fault clearing and is a line protection device used in order to prevent the influence of accident from expanding and in order to minimize the damage by promptly and accurately interrupting the current only in the fault section or opening when overload or fault current occurs after being installed at the service entrance of customer of extra high voltage under the ordinary load of 4000kVA (special load: 2000kVA) or below. |
