High Voltage and High Altitude Maintenance with Drone

China uses the "Little Flying Man" portable electric lift drone for online maintenance for the maintenance of the ±500 kV DC line, which prevented the common safety risks of electric tower climbing operations and improved the efficiency of operators.

Strong Wind Threats the Transmission Lines

In the power system, the exposed transmission lines regard the wind as a big "natural enemy". In order to resist the strong wind, the designers fully armed the line to form a fine wind-resistant design.

The porcelain disc insulator string

The porcelain disc insulator string, which assembled by several single disc insulator, is an essential component of electrical transmission and distribution systems. This type of insulator string is assembled by connecting individual porcelain disc insulators in series using metal or composite rods, designed to effectively support and insulate overhead power lines. Design and Structure: Porcelain disc insulator ANSI 52-3 is a widely used model of porcelain insulators under the ANSI standard. Multiple ANSI 52-3 insulators are strung together to form an insulator string. Each disc insulator is designed to evenly distribute electrical field stresses, preventing electrical arcing or leakage. These insulators are connected by rods made of galvanized steel or other suitable materials, providing mechanical strength and structural integrity.   Application: Insulator strings are primarily used in medium to high voltage overhead transmission lines. They are mounted on supporting structures such as transmission towers or poles, providing crucial support to conductors and electrical insulation between conductors and grounded structures. Features and Specifications: Voltage Rating: Porcelain disc insulator ANSI 52-3 insulator strings are designed to withstand specific voltage levels, ranging from several kilovolts to tens or even hundreds of kilovolts, depending on the application and system requirements. Mechanical:Strength: The series configuration...
