Box-type substation

A box-type substation, also known as a prefabricated substation or pre-installed substation, is a compact indoor or outdoor distribution device manufactured in a factory. It integrates high-voltage switchgear, distribution transformers, and low-voltage distribution units according to a specific wiring configuration. This innovative equipment organically combines functions such as transformer step-down and low-voltage power distribution into a single, fully enclosed, moisture-proof, rust-resistant, dustproof, rodent-proof, fireproof, anti-theft, heat-insulated, and mobile steel-structure enclosure. It is particularly well-suited for urban grid construction and renovation, representing a new generation of substations that has emerged following the traditional civil-engineered substations.

Ring Main Unit

The ring main unit is designed based on a ring-type distribution network, where the power supply trunk forms a closed loop. The power source feeds into the ring-shaped trunk, which then distributes electricity to individual distribution branches via high-voltage switches, such as load break switches.

Power transformer

Power transformers are critical stationary electrical devices used in power systems to step up or step down alternating current voltage and current. Their core function is to facilitate the efficient transmission, distribution, and safe utilization of electrical energy through the principle of electromagnetic induction.

High- and low-voltage complete switchgear

High- and low-voltage complete switchgear systems are modular electrical equipment clusters that cover both high-voltage (rated voltage > 1 kV, ≤ 35 kV) and low-voltage (rated voltage ≤ 1 kV) power distribution systems. Their core function is to achieve end-to-end management of electric power—encompassing “reception, conversion, distribution, control, and protection.” They serve as the “intelligent hub and neural network” of the power system, linking together all electricity-consuming scenarios, including power plants, substations, industrial enterprises, and civil buildings. These systems constitute the critical infrastructure that ensures the stable, safe, and efficient operation of the power grid.
