1.Function and service conditions

outdoor clavate post porcelain insulator mainly used for industrial frequency voltage 40.5 kV ~ 550 kV power substation power distribution equipment and outdoor electrical equipment and the live part insulation and support the use of

2. structure and process characteristics

This series of porcelain insulator for solid structure, plastic loaded part adopts cylinder structure on the sand. The sand is with the sand special pass strict process control granulation sand, with a combination of fine porcelain body performance and reasonable coefficient of expansion, can effectively improve the product of the mechanical strength. The product of the flange reasonable structure, while loading evenly stress distribution. Its material for high mechanical strength of nodular cast iron, hot dip galvanized surface. Excellent rust resistance ability. Plastic loaded with cement for high-grade cement, plus a reasonable maintenance technique, the strength of the porcelain got sufficient play. Any of voltage level products are all for simple columnar type, the structure is simple, long life and less maintenance, etc.

To ensure the reliability of the insulator of product only by defeat, ultrasonic detection and four to bending resistance loading test. 550 kV levels of great form of strut porcelain insulator bend destructive strength up to 20 kN.

Outdoor solid great form of strut porcelain insulator has the following characteristics: reasonable structure, high mechanical strength, the margin of the large, light weight, high reliability, long life.
