The pillar composite insulator can effectively use the narrow corridor to open and transmit electricity. It is suitable for the technical transformation of the city network. It can reduce the tower height and save a lot of manpower, material and financial resources. Because of its high bending strength, it can prevent the porcelain crossarm from appearing easily. The cascade fracture accident is a product that cannot be replaced by porcelain cross-arm; it is small in size, light in weight, strong in shock resistance and impact resistance, and does not require manual cleaning. It provides protection for safe operation. This product adopts integral rod design and compact structure. The quality is high and the weight is 1/10 of the same grade porcelain and glass insulators. It is very convenient for transportation and installation.
Suitable for use in dirty areas, high mechanical tensile loads, large spans and compact lines, the pollution flash voltage is 30%-50% higher than the same grade porcelain and glass insulators, and stable at -60 degrees to +200 degrees ambient temperature. The non-breakdown design adopts no need to measure zero value during operation, superior electrical performance and high mechanical strength. The tensile strength of the internal load-bearing epoxy glass rod is 2 times higher than that of ordinary steel. It is a high-strength porcelain material. ~10 times, effectively improving the reliability of safe operation.
