High and low voltage complete equipment includes: metal enclosed switchgear (switchgear), gas insulated metal enclosed switchgear (GIS), and electrical equipment such as high-voltage/low-voltage prefabricated substation low-voltage switchgear, distribution boards, control boxes, switch boxes, etc.

高压成套设备按其功能和作用的不同，可以分为：

High voltage complete equipment can be divided into:

（1）元件及其组合: 包括断路器隔离开关接地开关重合器分断器负荷开关接触器熔断器以及上述元件组合而成的负荷开关-熔断器组合电器接触器-熔断器（F-C）组合电器隔离负荷开关熔断器式开关敞开式组合电器等。

(1) Components and their combinations: including circuit breakers, disconnectors, grounding switches, reclosers, disconnectors, load switches, contactors, fuses, and load switch fuse combination electrical appliances, contactors, fuses (F-C) combination electrical appliances, isolation load switches, fuse switches, open type combination electrical appliances, etc.

（2）成套设备：将上述元件及其组合与其他电器产品（诸如变压器电流互感器电压互感器电容器电抗器避雷器母线进出线套管电缆终端和二次元件等）进行合理配置，有机地组合于金属封闭外壳内，具有相对完整使用功能的产品。如金属封闭开关设备(开关柜)气体绝缘金属封闭开关设备（GIS）和高压/低压预装式变电站等。

(2) Complete equipment: the above components and their combinations are reasonably configured with other electrical products (such as transformer, current transformer, voltage transformer, capacitor, reactor, arrester, bus inlet and outlet bushing, cable terminal, secondary components, etc.), organically combined in a metal enclosed enclosure, and have relatively complete use functions. For example, metal enclosed switchgear (switchgear), gas insulated metal enclosed switchgear (GIS), and high-voltage/low-voltage prefabricated substations.

低压成套设备包含低压开关柜，配电盘，控制箱，开关箱等电气设备。

The low-voltage complete equipment includes low-voltage switchgear, distribution boards, control boxes, switch boxes, and other electrical equipment.
