Why are Overhead Power Lines Loose on Utility Poles and Transmission Towers?In today's era of rapid technological advancement, the transportation of people, goods, and services has become significantly easier. Geographical distance is no longer a formidable obstacle. Just as these tangible entities can be efficiently conveyed over long distances, electricity also needs to be transmitted far and wide. However, unlike physical goods, electricity requires a medium for its journey.You may have frequ

Horizontal arrangement Uniform electric field distribution: In the horizontal arrangement, the three-phase conductors are on the same horizontal plane. This arrangement helps to make the electric field distribution around the conductors more uniform. A uniform electric field distribution can reduce the occurrence of corona. Corona refers to the discharge phenomenon that occurs when the air around the conductors is ionized under high voltage. It can cause power loss and radio interference. Facili

Benefits of Using Armored Cable in Electrical WiringArmored cable (Armored Cable) is a type of cable with an additional protective layer, typically used in applications that require higher mechanical protection and environmental resistance. Below are the main benefits of using armored cable:1. Enhanced Mechanical ProtectionCompression and Tensile Strength: The armor layer, usually made of metal materials (such as steel tape or steel wire), can effectively resist external pressure, tension, and o

Tests to Perform When Evaluating Cable SamplesWhen evaluating cable samples, a series of standardized tests are typically conducted to ensure their quality and performance meet the intended application requirements. These tests cover electrical performance, mechanical performance, environmental adaptability, and more. Below are common cable testing categories and their brief descriptions:1. Electrical Performance TestsThese tests are primarily used to verify the conductivity and insulation prope

How Engineers Test the Fatigue Resistance of WiresTesting the fatigue resistance of wires is a crucial step to ensure their reliability and safety during long-term use. Wires are subjected to repeated bending, stretching, and vibration in practical applications, so evaluating their fatigue performance is essential. Below are some methods and techniques that engineers typically use to test the fatigue resistance of wires.1. Bending Fatigue TestPurpose:To assess the durability of wires under repea
