Application And Process Characteristics Of Galvanized Cross-arm Insulators

Cross-arm insulator FS-35/5 outdoor solid rod-shaped post insulator is used in outdoor power stations, substation distribution devices and electrical equipment with power frequency AC voltage of 10-500KV for insulation and support of live parts.
The cross-arm insulator FS-35/5 modified series insulator porcelain parts are solid structures, and the glue-mounted part adopts a column sand-mounted structure. Our factory's porcelain formula is advanced and has excellent performance. After actual operation, the reliability is very high. The sand used for sanding is a special granulated sand that has been strictly controlled by the process. It has excellent bonding performance 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 distribution is uniform when it is stressed. The material of the cross-arm insulator FS-35/5 is ductile iron with high mechanical strength and hot-dip galvanized on the surface. It has excellent corrosion resistance. The cement used for glue-mounting is high-grade cement, and with reasonable maintenance technology, the strength of the porcelain is fully exerted. All products of any voltage level are single-column type, with the advantages of simple structure, long service life and less maintenance workload. In order to ensure the reliability of insulators, our factory conducts strike test, ultrasonic flaw detection and four-way bending load tolerance test on Parallel Groove Clamp one by one.
