Medium voltage surge arrester are electrical devices designed to protect electrical equipment from surges or transients that occur on medium-voltage power systems. These systems typically operate at voltages between 1kV and 36kV, and they are commonly found in various industries, such as manufacturing, oil and gas, and utilities. Medium voltage surge arresters work by detecting and diverting excess voltage away from the equipment and toward the ground. They are typically composed of metal oxide varistors (MOV) or zener diodes, which provide a low resistance path to the ground during transient events. When a surge or transient occurs, the surge arrester conducts the excess energy to the ground, protecting the equipment from damage. MV surge arrester are selected based on the specific application, voltage requirements, and surge current capacity. They are often installed in parallel with the equipment they are protecting, with a short path to the ground. Proper installation and maintenance are important to ensure the effectiveness of the medium voltage surge arrester. Application of Medium Voltage Surge Arresters surge arrester medium voltage are commonly used in a variety of applications, including power distribution systems, industrial facilities, and commercial buildings. They are installed to protect equipment such as transformers, switchgear, motors, and other medium voltage electrical components from voltage surges or transients caused by lightning, switching operations, or other sources. Medium voltage surge arresters are also used for the protection of telecommunication networks, data centers, and other critical electronic equipment. They play a significant role in ensuring the safety and reliability of power systems, protecting equipment from damage, and reducing the risk of operational downtime. Proper selection, installation, and maintenance of medium voltage surge arresters are essential to their effective operation and long-term service life.

Product Overview The ignition point of a fire inside the electric panel is mostly the part where the terminal block is fastened, so in order for initial fire extinguishing, the solution should be closely installed to the part where the terminal block is fastened. In the case of a small electric panel, a complete initial fire extinguishing is expected for fires occurring inside the electric panel by attaching the SFEX Pad to the top surface of the electric panel. Product Feature It has an excellent performance in the initial fire suppression as it can be installed near the ignition point as a flexible rope type. It uses a stand-alone method based on polymer chemistry so that it does not cause malfunctions and maintenance costs. The thermo-responsive Granule composed of KNO3 and subsidiary catalysts It does not affect the peripherals after the fire goes out. Function of SFEX Granule = fire extinguishing agent storage tank + temperature sensor + nozzle function Fire extinguishing method : Suffocation + subsidiary catalyst Example of Installation 1 : SFEX Line - If ducts exist Installing the SFEX Line horizontally or vertically in the ducts closest to the expected ignition points It can be installed without damaging the panel Example of Installation 2 : SFEX Line - If ducts do not exist Installing the SFEX Line horizontally or vertically, close to the expected ignition points of the Electric panel Example of Installation 2 : SFEX Pad - Small Electric Panel Simply attach it to the top inside the Electric panel.
Since 2018, export of black motors is continuously decreasing due to the new and stricter black motor export regulation. Most companies were not able to continue the export of this motor. However, DM Trading, with the help of its partner companies in Japan, is able to continue exporting black motors ensuring that all the requirements of the law are met. Detailed description: A.
