110kV-220kV Transformer Bushings from China Suppliers - Quality Factory Insulation for Power Transformers and Reactors
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.
Small size, light weight, high strength, any angle of mounting.
Easy transportation and mounting, maintenance-free.

Q: What is the main insulation design 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 impregnated with epoxy resin.
Q: What are the available external insulation materials and pollution classes?
The external insulation options include a porcelain envelope or composite insulation, suitable for anti-pollution class III and IV environments.
Q: What parameters can be measured using the test tap?
The test tap is located on the middle grounding flange and is designed to measure capacitance, dielectric dissipation (tanδ), and partial discharge quantity.
Q: What are the installation and operating environment requirements?
The bushing supports any mounting angle and operates in ambient temperatures between -45°C and +40°C. It must be installed in areas without chemical gas, extreme contamination, and salt fog.
Q: Can I request a customized design for the bushing?
Yes, customized design is available upon requirements based on a technical agreement with clients. We can design according to specific technical parameters of clients and specify dimensions of the CT grounding part.
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.
