The types of loads we connect to a building’s electrical system today vary greatly from what may have been connected 50 years ago. Today’s buildings rely heavily on electronics, communications, and microprocessors for some of the most basic functions. These include electronic controls built into a compact fluorescent or LED (light-emitting diode) light bulb, as well as sophisticated building control and automation systems. Automated systems are incorporated into a building’s emergency system as well. This increased use of electronics demands an electrical infrastructure that takes into account the increased sensitivity of electronic loads to voltage transients that can enter the electrical system. These transients can enter through external sources such as lightning and other electrical faults occurring outside the building, as well as through the routine switching of loads inside the building that occur as part of normal operations.

Since its establishment in 2006, Jinli Electric has been deeply involved in surge protectors for nearly two decades, adhering to the corporate mission of "creating the world's No. 1 lightning protection brand to protect users from lightning intrusion". The independently developed and produced surge protectors, lightning arresters, backup protectors, etc. are at the forefront of the industry in terms of quality and performance and are very effective in mitigating transient overvoltage. This prevents equipment damage or malfunction due to excessive voltage caused by switching, direct or indirect lightning strikes, or crossing of high-voltage power lines and low-voltage power lines. Better ensure the safety of the building itself and electrical equipment.

Transient events are by their nature very short, fast events, typically in the range of 5 to 200 microseconds. Momentary increases in voltage can create permanent conductive paths that can cause damage to electrical components. Today we need to better apply surge protectors to buildings to protect the safety of people and property.
