On March 28, 2025, a powerful earthquake shook Southeast Asia, causing strong tremors across Thailand. Although the epicenter was located in the Sagaing Region of Myanmar, the 7.7-magnitude quake severely impacted Bangkok and surrounding cities, leading to building collapses, transportation disruptions, and widespread panic. This disaster has become one of the most significant natural catastrophes of the year.

In modern electrical installation, safety and stability are factors that need to be given key consideration. Among various protective devices, OUV (Overvoltage and undervoltage Protection Device) and RCD (Residual Current Protection Device) are often mentioned simultaneously. Although they look somewhat similar, there are obvious differences in their working principles, application scenarios and protection functions.

Recently, we have frequently received feedback from customers that counterfeit products have been found in the YRO products they purchased, involving multiple items such as circuit breakers, combiner boxes, and surge protectors.

The Malaysia Green Energy Exhibition is an important renewable energy exhibition in Southeast Asia. The exhibition was held at the Kuala Lumpur Convention Centre and lasted for three days. Innovative enterprises and industry experts from all over the country will participate in the event to showcase the development of the sustainable energy field.

Routine inspections are essential for daily maintenance of solar distribution boxes. The primary concern is the overall condition and environment of the solar distribution box.

An isolating switch (also known as an isolator or disconnecting switch) is a high-voltage electrical component designed to provide a reliable, visible disconnection point in a power system. Its core function is to safely isolate a section of equipment—such as a transformer, capacitor bank, or cable—from the live power grid for maintenance, inspection, or circuit switching. Unlike circuit breakers, isolating switches cannot interrupt load current or fault currents (e.g., short-circuit currents). They must be operated only after the circuit has been de-energized or the current has been cut off by a circuit breaker. This makes them essential for creating a safe working environment in high-voltage applications, including renewable energy power stations, substations, and industrial plants.
