Performance Investigation of Polymer Isolator on Non-Soluble Pollutant of Distribution Sub Station

Isolator has an important role as a separator of lived voltage system with unlived voltage system in distribution and transmission line. It is also used as wire support in distribution and transmission line. The main usual problem in an isolator is the pollutant layer on the isolator surface. The pollutant layer on the isolator surface could lead to breakdown voltage that might harm the electrical systems and human being. The polluted isolator can be conducted by Equivalent Salt Deposit Density (ESDD) and Non-Soluble Deposit Density (NSDD). The NSDD is material that capable of absorbing water and binding the salt pollutant on the isolator surface, this could prevent the maximum natural cleaning process during rainy session.
