SF6 Gas Insulated Load Break Switch (Pole Mounted) |
|
| The SF6 gas insulated load break switch is a switchgear using SF6 gas of which the insulation and extinction performance is excellent, and is used in distribution lines to isolate sections of the main distribution lines / branches of lines, and is equipment that can provide information of various kinds to a master supervisory system. And control is possible through RTU. |
