110kV-220kV Transformer Bushings - High-Quality Insulation Solutions from China Suppliers and Factory
Advanced Software Design
Our company apply international advanced professional electric field analysis software and high voltage bushing internal insulation optimization design software package to optimize the design of internal and external insulation of bushing, core calculation and field strength, and obtain the optimal design scheme to ensure Higher electrical performance.
Precision Winding Technology
Our company adopt imported whole paper winder, using the whole paper winding process, seamless lap technology for paper and aluminum foil to achieve accurate electrode laser location and winding tension control, and ensure axial and radial field strength of condenser core uniform.
Vacuum Pouring & Drying
Our company use imported mixing material pouring system and vacuum drying system to ensure resin effectively degassed and core fully dry. So obtain smaller dielectric dissipation and lower partial discharge of bushing core, which ensure product good electrical performance.

HEADING-TYPE-1
High voltage parallel capacitors are suitable for parallel connection in AC power systems with power frequency (50Hz or 60Hz) of 1kV and above. They are used to compensate for inductive reactive power, improve power factor, improve voltage quality, reduce line losses, and fully utilize the efficiency of power generation and supply equipment.
