Abstract
An insulator is installed to support and insulate between an electrical pole and wire. Outmoded insulator of porcelain type has some defects. It has high-weight and flash & destruction often happen because of increasing of leak-current by high surface-energy of it. So now polymer insulator is developed to solve these demerits.

In Korea, polymer insulator is manufactured, but the core of polymer insulator , FRP rod is not manufactured because of problem of manufacturing technology (eg. low speed of manufacturing and bubble, etc.) Now the whole quantity of FRP rod is imported in Korea.

The localization of rod is studied in this paper. This FRP rod has the length 370mm, diameter 17.2mm, and is manufactured by pultrusion with glass & epoxy resin on this paper.

Five different kinds of pultrusion speed (100, 200, 300, 400, 500 mm/min) is applied to this development rod. This purpose is to study the characteristic of rod according to different speed and the best condition of mass-production.

And this development rod is tested on the specification "Standard Technical Specification of Korea Electric Power Corporation (ES) and Canadian Electrical Association (CEA), American National Standard for Insulator (ANSI), International Electrotechnical Commission (IEC)"

From this study, we can know the maximum speed is 500mm/min.

Forwards, I will study about Ø22mm insulator for power transmission, Ø40mm insulator for railroad besides this development rod 'Ø17.2mm'.
