AC normal type porcelain disc insulators are used in the transmission and distribution line of electrical power. Normal type insulators are suitable for general areas, such as the appropriate increase in the number of insulator pieces can improve the foul flash performance.

Insulators are made of porcelain parts, iron caps and steel feet glued together by not less than 525 silicate cement and quartz sand cement. Insulator surface is generally painted white glaze, brown glaze, can also be drawn according to the need for other glaze colors.

The products are manufactured in accordance with GB/T 7253, IEC60305 standards.

Part Ⅰ: Product Advantages

1. Low cost, cheap price

2. Good insulation performance

3. Good heat resistance

4. Suitable for use in AC lines in clean areas
