Product Detailed
1. quality guaranteed porcelain insulator 2. good price and fast delivery 3. many types and satisfactory service

Insulators used for high-voltage power transmission are made from porcelain.

Porcelain insulators are made from clay, quartz or alumina and feldspar, and are covered with a smooth glaze to shed water. Insulators made from porcelain rich in alumina are used where high mechanical strength is a criterion.

Porcelain has a dielectric strength of about 4–10 kV/mm.

porcelain insulator has a long life time

This is the behavior of the electric field on the surface of a high voltage insulator with conductive contamination. The model consists of a dielectric cylindrical insulator (epoxy resin) which is capped by two electrodes and contaminated by seven water drops. The frequency of the alternating voltage is 50 Hz and a voltage gradient of 500 V/mm is applied.
