110kV-220kV Transformer bushings

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.

1. ● 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.
2. ● External insulation is porcelain envelope or composite insulation.
3. ● Pollution class is anti-pollution class III , IV .
4. ● Test tap to measure capacitance , dielectric dissipation (tanδ)and partial discharge quantity is set on the middle
5. grounding flange;
6. ● End shield to improve electric field distribution of bushing
7. tail is equipped on the rail of bushing (on transformer side);
8. ● Good sealing and performance;
9. ● Oil-free, gas-free, explosion-proof, Green Environmental Protection
10. ● Small size, light weight, high strength ,any angle of mounting;
11. ● Easy transportation and mounting, maintenance-free; ● Stable operation and high reliability.

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.
