Welcome to our online file sharing project. Today's topic is Polymer Insulators. This topic is originally presented by Aniruddha Kulkarni at Walchand College of Engineering, Sangli.
Introduction to subject:
1. —Overhead line insulators are used to support the line conductors at tower or poles and to separate them electrically from each other.
2. —Polymer insulators are known as non ceramic insulators or composite insulators.
3. —This insulators mostly are used where high humidity and high temperature in atmosphere is present such as Arabian countries.
4. —Polymeric insulators have proved itself in many locations through the worlds as very good insulator against contamination
5. —Silicone rubber insulating material is considered through laboratory evaluation and field experience as the most suitable for HV application in harsh environment.
6. —The construction of the polymeric insulator, type of shed material, end fitting, fiber glass rod and manufacturing process are decisive factors in the overall insulator performance
— 7. —The GCC weather conditions are very harsh and require careful selection for the polymeric insulator.
8. —There is clear need to adopt short and long term evaluation methods for the polymeric insulator in cooperation with researching universities and testing laboratories.
