Column insulators are 1 kinds of insulators that are made of high-strength cement and added with special adhesives to glue the insulating porcelain on the metal base.

Column insulators are 1 kinds of insulators that are made of high-strength cement and added with special adhesives to glue the insulating porcelain on the metal base. Sometimes they also include stud bolts or one or more bolts installed on the metal base. These components are rigidly installed on the supporting structure. It is mainly used for insulation and support conductors in overhead lines with nominal voltage higher than 1000V, frequency less than 100Hz and altitude less than 1000m. The ambient temperature at the installation site is usually between -40°C and 40°C.

The performance and characteristics of insulators

The main electrical performance of insulators is their flashover characteristics. To avoid breakdown during operation, the breakdown voltage of the insulator is higher than the flashover voltage. Insulators of different voltage levels have different withstand voltage requirements.

An insulator is a special insulating component.

Insulators are a special type of insulating component that play an important role in overhead power transmission lines. They are used to isolate the conductive parts of electrical equipment from the grounded parts or another conductive part, maintaining electrical insulation and ensuring the safe and stable transmission of electricity.

Definition and Composition of Composite Insulator

Composite insulator, also known as synthetic insulator, consists of three parts: glass fiber epoxy resin pull rod (also known as epoxy glass fiber reinforced plastic core rod), silicone rubber umbrella skirt, and metal fittings. This type of insulator has excellent insulation performance and mechanical strength, making it an indispensable component in power transmission and distribution systems.
