ZS-35/4 pillar insulator ZS-35/400 high voltage insulator

>
>1. Purpose and use environment consultation telephone power plant
Outdoor solid rod pillar insulators are used in power frequency AC voltage outdoor power stations, substation power distribution devices and electrical equipment. For insulation and support of live parts.
The applicable environment of insulators is ~+, and some products can be used in areas with an altitude of ~+. The products are divided into two categories: ordinary type and stain-resistant type. The stain-resistant type can be applied to medium, heavy and extra-heavy stained areas.
>2. Structural and process characteristics
The porcelain parts of the series of insulators are changed to a solid structure, and the adhesive part adopts a cylinder sand structure. Our factory's porcelain formula is advanced and has excellent performance. After actual operation, its reliability very high. The sand used for sanding is special granulated sand that has undergone strict process control. It has excellent bonding properties with the porcelain body and a reasonable expansion coefficient, which can effectively improve the mechanical strength of the product. The flange structure of the product is reasonable, and the stress is evenly distributed when subjected to force. Its material is ductile iron with high mechanical strength and its surface is hot-dip galvanized. Has excellent rust resistance. The cement used for glue installation is high-grade cement, coupled with reasonable maintenance technology, the strength of the porcelain has been fully exerted. Products of any voltage level are single-column type, which has the advantages of simple structure, long operating life and low maintenance workload. In order to ensure the reliability of insulators, our factory conducts individual impact, ultrasonic flaw detection and four-way bending load test on the products.
