Overview
High voltage shunt capacitor is mainly used in the A.C,Power system with 50Hz or 60Hz to improve power factor, reduce reactive power loss, improve voltage quality. it is national recommended energy saving products.
Main features
Casing: Cold-pressed, anti-fouling type casing is adopted, and the creepage distance is not less than 31mm/kV.
Mature internal fuse technology.
After testing, the internal fuse can isolate the faulty component within 0.2ms, the release energy of the fault point is not more than 0.3kJ, and the remaining intact components are not affected.
Advanced concealed internal fuse structure, using oil gap arc extinguishing, reducing the possibility of blasting the capacitor case.
The internal fuse protection and relay protection have perfect coordination standards to ensure the safe and reliable operation of the entire device.
Liquid medium: 100% insulation oil (NO PCB) is used. This liquid has excellent low temperature performance and partial discharge performance.
The main insulation adopts a composite insulation structure, which not only guarantees excellent electrical performance, but also has a certain degree of mechanical strength, which ensures that the insulation of the capacitor complete set of devices is 100% reliable without protection.
Parameters
High voltage shunt capacitor are suitable for 50Hz or 60Hz AC power systems to improve the power factor of the power system, reduce line losses, improve the quality of the power supply voltage, and increase the active output of the transformer.

Strange Devices on Transmission Lines: 5 Little-Known Practical Functions（1）1 Aviation Warning SpheresAviation warning spheres, also known as reflective safety spheres, are used on overhead transmission lines near airports, especially on extra-high-voltage (above 220kV) lines and river-crossing transmission lines. Highly visible aviation marker spheres (aviation warning spheres) must be installed along the lines to provide warning signals.The aviation marker sphere (aviation warning sphere) has a diameter of ф=600mm. The sphere can be manufactured in various bright coloLeon09/04/2025 -
Transmission LineIn transmission lines, a "π" connection involves breaking the original line from Substation A to Substation B and inserting Substation C, forming a "π" configuration. After the "π" connection, the original single line is divided into two independent transmission lines. Following the "π" connection, Substations B and C may both be powered by Substation A (in this case, Substation C receives power via a feeder from Substation B's busbar, or possibly from another voltage point within Substation B);Encyclopedia09/04/2025 -
What are the principles of forced re-energization of transmission lines?Principles of Forced Re-energization of Transmission LinesRegulations for Forced Re-energization of Transmission Lines Correctly select the forced re-energization end of the line. If necessary, change the connection configuration before forced re-energization, taking into account the reduction of short-circuit capacity and its impact on grid stability.
