China Transformer Bushings for 110kV-220kV Power Transformers and Reactors - Quality Suppliers & Factory Direct
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.
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.
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.
The main insulation of resin impregnated paper (RIP) bushing is condenser core combined by crepe paper and aluminum foil, which is cured after impregnated with resin epoxy.
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.

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 fully cured after being impregnated with epoxy resin.
What are the environmental limits for installing these bushings?
The bushings are designed to operate in ambient temperatures ranging from -45°C to +40°C. They are suitable for installation at any mounting angle, provided the area is free from chemical gas, extreme contamination, and salt fog.
How is electrical performance optimized during manufacturing?
We utilize advanced electric field analysis and high voltage bushing insulation optimization software. Additionally, we adopt imported whole paper winders with seamless lap technology and laser electrode positioning to ensure a uniform field strength across the condenser core.
How does the company achieve low partial discharge and dielectric dissipation?
By using an imported mixing material pouring system and a vacuum drying system, we ensure that the resin is effectively degassed and the core is fully dry, yielding minimal dielectric dissipation and lower partial discharge.
What customization options are available for ordering?
Clients can specify product codes, rated voltage/current, creepage distances, and CT grounding dimensions. We also offer fully customized designs based on client outline dimensions and technical agreements.
What are the structural safety and maintenance advantages?
The RIP bushings are oil-free, gas-free, explosion-proof, and environmentally friendly. They are compact, lightweight, maintenance-free, and easy to transport and mount at any angle.
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.
