When the thunderstorm season is coming, lightning protection is particularly important at this time. Lightning enters the room through power lines or other ways, causing damage to people and equipment; LEIHAO Lightning Protection Company has many excellent lightning protection products, of which the surge protector of power supply is an important part. Now we will briefly introduce the parameters and uses of a first-class surge protector.

LH-15I series surge protectors are designed to meet the protection requirements of all low-voltage devices for industrial lightning surge. The product range of this series is classified by product type and power supply category (AC or DC).
1. product design standard: this product is designed according to relevant international standards IEC, and its performance meets the requirements of national standard GB 18802.1-2011 "low voltage surge protector (SPD) part 1: performance requirements and test methods of surge protector for low voltage distribution system". 2. Scope of product use: GB50343-2012 Technical Code for Lightning Protection of Building Electronic Information System 3 Selection of surge protector: The primary SPD must be set in the main distribution box at the entrance of building power supply. 4. Product features: This product has the characteristics of low residual voltage, fast response speed, large current capacity (impulse current Iimp(10/350μs) is 25kA/ line, long service life, simple maintenance and convenient installation, etc. 5.Working temperature: -25℃ ~+70℃, working humidity: 95%.Risk of voltage surges Electrical and electronic eauipment is indispensable in the daily activities of today’s businesses and individuals. Such devices are connected to the electricity grid, often exchanging data and signals through communication lines and are usually sensitive to disturbances. These interconnecting networks provide a propagation path for overvoltages. Protection against lightning and overvoltages not only ensures the safety of people,goods and equipment, but also ensures continuity of installation services. Overvoltage protection extends the life of the equipment by more than 20%, which significantly reduces the volume of electronic waste. It also reduces the power consumption of the installations, all of which translates into cost savings and environmental sustainability.
