Our Remote Terminal Unit is LBS (Load Break Switch) and ACR (Automatic circuit recloser ) microprocessor controller.

Control cubicle is heat insulated to minimize temperature variation and protected controller from solar heating as adopting sunshine cover to the outside and heat insulation inside of control cubicle. Vents of the control cubicle are screened against vermin’s entry and door is sealed with a gasket.

Our microprocessor controller are fully protected from entry of moisture and condensation able to use any places where tropical, moderate and severe humidity area is located on.All the measured values and event records are stored in the microprocessor control for Sending data to SCADA system or off-line checking maintenance and analysis. All telemetry communication can be supported with DNP3.0, MODBUS, IEC60870-5-101/104 communication protocols

Sensitive sensors provide to incorporate the functions of an over-current protection relay, a ground fault relay, a sensitive earth fault relay and to measure line current, voltage amount, real and reactive power, power factor, demand watts and VARs, frequency and so on.

Recloser mechanical parts are drastically reduced, resulting from high reliability and maintenance free operation during the life time. We use low-voltage power source supplying from low voltage distribution line by Solar Panel or PT and a fully charged battery and trip and close capacitors provide Recloser operation over hundreds of open-close operations as back-up upon loss of control Power. This allows Recloser operation independent of the high voltage supply, the low voltage supply and the battery and capacitor conditions with dead line operation capability required for SCADA and distribution Automation.

Load Break Switch

SF6 gas insulated load break switch (LBS) for overhead lines operating at a voltage up to 38kV. It meets the demand for oil-less and maintenance free operation with SF6 gas, related parts and devices installed inside its hermetically sealed stainless steel tank. It can be manually operated or motorized.

Since the electric conduction part in it is completely sealed, and it has excellent insulated electric lines, the switch is easy to function as well as is free from accidents resulting from the contact with salt, air pollution, and strange materials. In case of abnormal rise of interior pressure of the switch, it is equipped with pressure-proof equipment which can prevent the vessel from being destroyed


Air Insulated load Break Switch have stable switching close/open characteristic that maintained both during electrical and manual operation at the time of main circuit section’s switching close/open by leveraging spring operation mechanism.
Air compressed at the inside of unique structure’s cylinder breaks stable load current and enables insulation recovery within 0.5 Cycle by dispensing powerful compressed air with Arc Nozzle through the hole for velocity increase situated at the inside of Insulator with outstanding insulation characteristics.
Remote manual operation device that facilitates installation when connecting to switch :
Connector for manual operation of panel door and Easy of installation to enable installation of remote manual operation device at the front and rear of switch to facilitate installation of main generator or panel wall surface without intervention


Pad mounted load break switch have puffer interrupting and fully dead front switchgear for underground  system up to 25.8kV, 600A, enclosed in stainless steel tank full of SF6 gas insulation media. It incorporates grounding switches in every way to provide added safety and faster working.


Advantage of our products
– It guarantees perfect break capacity by high insulation and excellent fire-fighting capacity of SF6 Gas.
– NO fire danger By using inflammable SF6 Gas so can use indoor and out door
– The use of Puffer fire-fighting is compressed in the cylinder allows excellent opening-closing capacity
– Both the opening-closing surge occurring when using vacuum interrupter and flash over phenomenon by charged electric current of cable do not happen.
– The grounding switch inside allows grounding with a simple operation.
