Advantages and Disadvantages of Ceramic Insulators

Porcelain insulators have good chemical stability and thermal stability, almost no aging deterioration, and has good electrical and mechanical properties. There are large diameter, L00 ~ 400KN large tonnage, ordinary type and bell-type umbrella and other new varieties appear. But in general, the number of porcelain insulator manufacturers in these years has not increased substantially, but in the same fierce competition in the market through the integration and reorganization in the reduction. Toughened glass insulators with zero self-breaking, easy to detect the characteristics of the actual use can fully demonstrate the good performance advantages, the performance of good function and role, tempered glass insulator with zero self-breaking characteristics. As long as the ground or on the helicopter can be observed, without the pole piece by piece detection, reducing the labor intensity of workers.

Product structure and stain resistance is the key. Glass insulator with cylindrical head structure, bearing force components evenly. Compared with the traditional porcelain insulator for decades, the tapered structure has the characteristics of small size, light weight, high strength and excellent electrical performance. As the glass linear expansion coefficient is much larger than the porcelain, the outer dimensions are much smaller than the composite insulation material, and easy to connect with the metal accessories and cement, and thus the components of the matching material is good. In a variety of climatic conditions, not like porcelain insulators and composite insulators as easy to produce dangerous stress and lead to aging. And the composite insulator is difficult to solve the structural quality of the composite interface.
