1、 Purpose and usage environment

Outdoor solid rod shaped post insulators are used for insulation and support of live parts in outdoor power stations, substations, distribution equipment, and electrical equipment with AC voltages ranging from 10-500KV.

Insulators are suitable for environments ranging from -40 to+40, and some products can be used in areas with an altitude of 4000m. The products are divided into two categories: ordinary shape and stain resistance, with stain resistance suitable for medium, heavy, and extremely heavy stain areas.

2、 Structure and process characteristics

The ceramic components of the series insulators are changed to solid structures, and the adhesive part adopts a sand structure on the column. Our factory's ceramic formula has been improved, and the performance is excellent. After actual operation, the reliability is very high. The sand used for sanding is granulated sand that has undergone strict process control. It has excellent bonding properties with the ceramic 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 subjected to force. Its material is ductile iron with high mechanical strength, and the surface is hot-dip galvanized. Has excellent corrosion resistance. The cement used for bonding is high-grade cement, and with a reasonable curing process, the strength of the porcelain is fully utilized. Products of any voltage level are single column type, with advantages such as simple structure, long service life, and low maintenance workload.
