LW3F series 15KV/27KV/38KV SF6 Load Break Switch

The switch can equipped with a controller with most advanced technical parameter.

LW3F-A type LW3F is manually LBS for choice.

LW3F-M type LW3F is a intelligent type LBS for choice. 

It can automatically disconnect when the distribution line was break down. 

It could operated by handle; Implement electrification and distant. The electric controller was installed in stainless steel cabinet. So it could use in any conditions.

Volt logic series line sectional load break controller is medium voltage overhead line grid monitoring unit, It can combined with load break switch for achieve of measure monitoring, fault analysis and event records. It gives us a safety power grid for cutting line fault and automatic recovery operation and power automation.

The controller is gathering with line protection, control, measurement and monitoring of voltage and current signals integrated automation and control devices outdoors.

The controller is a automatic management unit for single way/multi ways/ring network /two power sourcing, provided with all voltage and current signals and all functions.

The controller column switch intelligent controller supports:Wireless (GSM/GPRS/CDMA), Ethernet mode, WIFI, optical fiber, power line carrier, RS232/485, RJ45 and other forms of communication, and can access other station premises equipment (such as TTU, FTU, DTU, etc.).
