Can DCL Actuators Be Used in High-Altitude Areas?

High-altitude environments present unique challenges that can impact the performance of DCL electric actuators. This report evaluates their usage at 3,000 meters above sea level. 1. How High Altitude Affects Electrical Products As altitude increases:✔ Air density and pressure decrease, leading to lower insulation strength and increased risk of electrical breakdown.✔ Cooling efficiency decreases, causing […]

Why Do Some Actuators Need Explosion Protection?

1. What is an Explosion? An explosion occurs when flammable substances mix with oxygen and ignite under certain conditions. If the reaction speed exceeds the speed of sound, it results in a destructive explosion wave. 2. What is Explosion Protection? To prevent explosions, at least one of the three key factors must be controlled: […]
