Which electrical characteristics of polymer pin type insulators?
Polymer pin type insulators are made of an insulator silicone rubber use; you can also call composite pin insulator. Polymer pin type insulators are used in high-voltage lines, can replace porcelain pin insulators.
characteristics of polymer pin type insulators
Waterproof polymer pin type insulators well, cannot easily be destroyed in the rain or humid environment. Excellent aging resistance and corrosion resistance can make use of the transmission line in time polymer pin type insulators longer.
Polymer pin type insulators there are many excellent electrical characteristics, such as: strong tensile strength, flexural strength, high impact resistance, light weight, easy to install. But the polymer pin type insulators are also some disadvantages, such as the mandrel is very brittle and easy to break.
Size polymer pin type insulators installed at both ends of the same type fittings, so due to damage or other reasons need to be replaced, it can be more convenient to complete.
