ZDVolt bushings are classified by main insulation type into OIP, RIP, RIS, P&O (porcelain oil-filled), SEC (epoxy resin cast), and GIS outlet type. By application medium/interface, they are divided into oil–air, oil–oil, oil–gas, gas–gas, air–gas, and air–air (wall bushing). Voltage ratings: AC up to 1100 kV; DC up to ±800 kV. Current ratings: low-voltage, high-current up to 45,000 A. Our standard bushings comply with IEC and GB standards. We also develop bushings to meet IEEE, JEC, IS, and other international standards. In addition, we design custom bushings for special equipment and provide solutions for replacing bushings on existing transformers.
