Overview

The GG] type low-voltage distribution reactive power compensation integrated cabinet is a new type of outdoor distribution reactive power compensation integrated cabinet designed based on the principles of safety, economy, rationality and reliability. This new type of outdoor comprehensive distribution box is suitable for urban and rural power grid renovation, industrial and mining enterprises, street lighting, residential communities and other AC 50Hz, rated voltage 380V distribution systems. It has multiple functions such as power distribution, control, protection, reactive power compensation and power metering. At the same time, leakage protection function can be added according to the user's requirements. The product features a novel and reasonable structure, a high protection level, and is convenient for installation, debugging, maintenance and repair. The product complies with GB7251.1-1997 and GB/T15576-2008, and has passed the 3C certification. It is an ideal low-voltage complete set of equipment in the current power grid transformation.

The GG] series outdoor distribution reactive power compensation integrated cabinet is suitable for the distribution, metering, protection and automatic reactive power compensation of 0.4kv voltage level electric energy.

Product Features
