General

LW3F type pole-install load switch was used in 12kV,24kV,33kV rated voltage, rated current 400/630A; 50/60HZ with the load current; over load current of power line open circuit and opening and closing electric systems.The switch can equiped with a conttoller with most advanced technical parameter.

LW3FA type LW3F is manaully LBS for choice.

LW3FM 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; Implementt electro motion and distant. The electric controller was installed in stainless steel cabinet. So it could use in any conditions.

Product Structure

Controller

Voltlogic series line sectionalizing 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.).
