SF6Gas Insulated Ring Main Unit (RMU)

ENTEC SF6Gas Insulated Ring Main Unit is designed to have distribution level of up to 24kV, and rated currents up to 630A. Mainly used in malls, shopping centers, industrial areas and other locations of where the load is concentrated and areas with increasing demand of load. It is installed on the ground at the withdrawal point to prevent the fault spreading out to other branch line. It contains tee-off circuit breaker that has stainless steel enclosure and insulate with SF6gas in 3-position switch.

By adopting vacuum interrupter, it can perform 2,000 times of mechanical operation. In addition, each phase is mechanically interlocked with main circuits to maximize the safety.  Self-powered relay is available for precisely operating at a set time and detect fault current. For monitoring line in distribution automation system, digital relay controller can be equipped as an optional to be configured to the system.

Protection Devices

We supply protection devices, which protect electrical power systems from faults. Our devices are designed to isolate faulted parts of the system from the rest of the electrical network to prevent the rest of the system from getting affected. 

Communication Products

We provide sophisticated, quality communication products to assist energy providers and utilities address energy issues. Our cutting edge solutions improve asset management, metre security, energy efficiency and more.

Fault Path Indicators  

Our Fault Path Indicators provide transient data to indicate areas of the network that are ill-performing so that utility can plan maintenance to reduce future interruptions.

Voltage Regulators  

Voltage Regulators  

We provide Toshiba Regulators which are used in distribution lines and replace three-phase regulators. These regulators are used to maintain and regulate the load voltage in long lines, strategic points or substations.
