Product introduction:

GGJ low-voltage reactive power intelligent compensation device adopts computer aided design (CAD), introduces microcomputer control, and implements intelligent tracking compensation for reactive power. Its structure is reasonable, and its technology is perfect. It is widely used in low-voltage power grids to improve power factor, reduce reactive power loss, and improve power supply quality. It is a new energy-saving product. It is specially used for reactive power compensation of 130-600kVA three-phase transformer.

Working conditions:

◆ Altitude: ≤ 2000m;

◆ Ambient temperature: - 20 ℃~+45 ℃;
