HY5(10)W-21 HY5(10)W-21J Surge Arrester

The lightning arrester is designed to provide superior protection and stand the test of time, ensuring the safety of your electrical system.

 Zinc oxide arresters have unique nonlinear volt-ampere characteristics that allow only a small amount of current to flow under normal operating voltage. This ensures minimal energy losses and efficient operation. When an overvoltage action occurs, the resistance of the arrester drops sharply, releasing voltage energy and effectively protecting the system from potential damage.

 This arrester differs from conventional models in that it has no discharge gap. Instead, it harnesses the power of nonlinear characteristics to provide reliable protection without the need for additional components. This eliminates the risk of gap failure and ensures continuous, reliable performance.

 In addition to their advanced protection features, zinc oxide arresters can withstand a wide range of environmental conditions. The arrester has a power supply frequency range of 48Hz to 60Hz, an ambient temperature range of -40°C to +40°C, and a maximum wind speed of 35m/s, allowing it to operate in harsh conditions. It is also capable of operating at altitudes of up to 2,000 meters, withstanding seismic intensities of up to 8 degrees, and withstanding ice thicknesses of up to 10 meters.

 Additionally, arresters are designed to withstand long-term applied voltages without exceeding their maximum continuous operating voltage. This ensures that it provides consistently reliable protection over extended periods of use, making it a reliable choice for a variety of applications.

 Whether you are looking to protect your electrical system from overvoltage events or ensure reliable performance in challenging environments, zinc oxide surge arresters are a solution you can trust. With its advanced features, durable construction and unparalleled protection, it is ideal for any application where electrical safety is critical. Invest in a zinc oxide surge arrester and enjoy the peace of mind that your system is protected by the best electrical protection technology available.
