110kV-220kV Transformer Bushings by China Suppliers | High-Quality Factory Products for Power Transformers and Reactors
Optimized Design Software
Our company applies 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, obtaining the optimal design scheme to ensure higher electrical performance.
Precision Winding Process
Our company adopts an imported whole paper winder, using the whole paper winding process and seamless lap technology for paper and aluminum foil to achieve accurate electrode laser location and winding tension control, ensuring uniform axial and radial field strength of the condenser core.
Vacuum Drying & Pouring
Our company uses an imported mixing material pouring system and vacuum drying system to ensure resin is effectively degassed and the core is fully dry. This achieves smaller dielectric dissipation and lower partial discharge of the bushing core, ensuring excellent electrical performance.
The main insulation of resin impregnated paper (RIP) bushing is a condenser core combined by crepe paper and aluminum foil, cured after being impregnated with epoxy resin.
External insulation is porcelain envelope or composite insulation.
Pollution class is anti-pollution class III, IV.
Test tap to measure capacitance, dielectric dissipation (tanδ), and partial discharge quantity is set on the middle grounding flange.
End shield to improve electric field distribution of bushing tail is equipped on the rail of bushing (on transformer side).
Good sealing and performance.
Oil-free, gas-free, explosion-proof, Green Environmental Protection.
Small size, light weight, high strength, any angle of mounting.
Easy transportation and mounting, maintenance-free.
Stable operation and high reliability.

What materials make up the main insulation of the RIP bushing?
The main insulation of the resin impregnated paper (RIP) bushing is a condenser core combined by crepe paper and aluminum foil, which is cured after being fully impregnated with epoxy resin.
How does the company guarantee the uniform field strength of the condenser core?
We adopt an imported whole paper winder, using the whole paper winding process and seamless lap technology for paper and aluminum foil. This achieves accurate electrode laser location and winding tension control, ensuring uniform axial and radial field strength.
What are the environmental requirements for installing these bushings?
The bushings are designed to operate in ambient temperatures from -45°C to +40°C, can be mounted at any angle, and should be placed in areas without chemical gas, extreme contamination, and salt fog.
Are customized designs available for specific client requirements?
Yes, customized design is available based on technical agreements with clients. We can design according to the specific technical parameters and various outline dimensions provided by the client.
What testing features are built into the grounding flange?
A test tap is set on the middle grounding flange to measure capacitance, dielectric dissipation (tanδ), and partial discharge quantity.
Why do these RIP bushings have lower partial discharge and dielectric dissipation?
We utilize an imported mixing material pouring system and a vacuum drying system. This process ensures the resin is effectively degassed and the core is fully dried, resulting in smaller dielectric dissipation and lower partial discharge.
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.
