The technical center is equipped with testing and testing equipment: 1 set of 400kN mechanical load puller, 1 set of 1000kN mechanical load puller and 1 set of 2000kN mechanical load puller. The high-voltage testing hall is equipped with one set of 1000kV power frequency test device, one set of 1350kV steep slope test device, one set of wind load test device, one set of large flexion and extension test device and one set of small flexion and extension test device. The physical and chemical laboratory is equipped with one set of leakage tracking device, one silicone rubber tear strength testing machine and one silicone rubber sulfur testing machine. The composite insulator for high-speed electrified railway contact network developed by Hebei Province is transformed by scientific and technological achievements in Hebei Province. The center has identified the products and its products have reached the domestic leading level. The ultra-high voltage and ultra-high voltage AC 750kV-1000kV composite insulator manufacturing technology has reached the international advanced level. Tsinghua University first used the pollution simulation to optimize the product structure and fill the gaps at home and abroad. Its products have independent intellectual property rights and all have achieved large-scale production.
