During the continuous transformation and construction of the urban distribution network, a large number of overhead lines in the city were replaced by cable lines, and the pole switches were replaced by switch cabinets. DFT6-12 (40.5) outdoor ring network box is a new type of power supply equipment designed by Tianan Electric to cooperate with the 10kV (35kV) power network cable system. It is widely used at the cable node in the 10kV (35kV) system as the reception and distribution of electric energy. For use. Each ring network line in the product is equipped with a load switch or vacuum circuit breaker, any branch circuit can be freely exited and put into operation, and other ring network circuits are not affected. When the combined electrical scheme is adopted, when a short circuit fault occurs in a branch circuit, the fuse on the branch circuit can quickly disconnect the fault circuit and hit the release of the load switch to open the fault circuit. This ensures that the fault circuit is isolated. Continuity of power supply for non-faulty branch circuits.

ZGS-Z(H)/12 combined transformer (American box substation) is a series of products developed by Tianan Electric after digesting and absorbing foreign advanced technology. It is used in 10/0.4kV, 50Hz power distribution system. The rated capacity of the transformer is 50 ~1600kVA.

DBW1A-12 light box buried substation is a new substation product developed by Tianan Electric for the transformation of urban distribution network. It can be used in ring network power distribution system, and can also be used as a radial grid terminal for power supply.

The ZBW3-40.5 series of prefabricated substations combine 35kV high voltage electrical, 35/10, (6), (0.4)kV power transformers, 10kV switch cabinets, 0.4kV low voltage cabinets, DC battery screens, and relay protection screens according to the predetermined plan A set of high-voltage substations combined together. There are two types of structure: integral type and split type, which are welded into a frame after protection treatment by section steel, and covered with aluminum alloy plate
