GJ Low voltage intelligent reactive power compensation cabinet
GJ low-voltage intelligent reactive power compensation cabinet, is specially designed for the actual situation of the power grid. It adopts intelligent control technology, which effectively solves the problem of automatic switching of parallel capacitors for reactive power compensation under harmonic conditions. On the other hand, it can filter out harmonics according to users' actual requirements, clean the power grid environment, reduce losses, and eliminate harmonic hazards; And provide capacitive reactive power to the system to improve power factor. Can be used in power distribution systems for industries such as electricity, metallurgy, petrochemicals, industrial and mining enterprises, construction, and machinery.
GTDXF囗-12 AC metal solid insulated ring main switchgear
AC metal solid insulated ring main switchgear is a fully insulated, fully sealed, and maintenance free solid insulated vacuum switchgear. All high-voltage live parts are cast with epoxy resin material with excellent insulation performance, organically combining the vacuum arc extinguishing chamber, main electrical circuit, insulation support, etc. into a whole, and the functional units are connected through fully insulated solid busbar. Therefore, the entire switchgear is not affected by the external environment, ensuring the reliability of equipment operation and the safety of operators. This ring main unit has the characteristics of simple structure, flexible operation, reliable interlocking, and easy installation. It is suitable for 50Hz, 12 kV power systems and widely used in industrial and civil cable ring networks and distribution network terminal projects. It is used for the reception and distribution of electrical energy, especially for urban residential distribution, small substations, switch stations, cable branch boxes, box type substations, industrial and mining enterprises, shopping malls, airports, subways, wind power generation, hospitals, sports stadiums, railways, tunnels and other places. Due to its advantages of full insulation, full sealing, and full shielding, this product is particularly suitable for use in harsh environments such as high altitude, high temperature, humid heat, severe cold, and serious pollution.

- Product Description
-
The YBD-12 series box type underground transformer substation mainly consists of two parts: an underground transformer (including a prefabricated pit) installed underground and an outdoor advertising light box type high and low voltage switchgear installed on the ground. Among them, underground transformer is a new type of distribution transformer with high-voltage fuse protection that can operate submerged in water for a period of time. They have been widely used in airports, highways, bridges, tunnels and other places in China; The interior of the outdoor light box type high and low voltage switchgear is an outdoor high and low voltage distribution cabinet, and the outer side of the box is an advertising light box. The content of advertising posters can be designed according to the surrounding environment and user requirements. The entire product covers a small area, beautiful and generous, not only highly coordinated with the surrounding environment, but also serves as an advertisement. This product complies with the following standards: GB17467 "High Voltage/Low Voltage Prefabricated Substations" DL/T537 "Selection Guide for High Voltage/Low Voltage Prefabricated Box type Substations".
