General Electric electrical components refer to switching devices capable of closing, carrying, and breaking current under normal circuit conditions, and capable of closing, carrying, and breaking current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague; generally, equipment above 3kV is referred to as high-voltage electrical apparatus. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. When severe overload, short circuit, or undervoltage faults occur, they can automatically cut off the circuit. Their function is equivalent to a combination of fuse-switches and over/under thermal relays. Moreover, component replacement is generally not required after interrupting fault currents. They have been widely applied. In the generation, transmission, and use of electricity, power distribution is an extremely important link. Distribution systems include transformers and various high- and low-voltage electrical equipment, while low-voltage circuit breakers are a type of electrical apparatus with extensive usage.

General Electric electrical component structure

Generators are typically composed of stators, rotors, end covers, bearings, and other components. The stator consists of the stator core, winding coils, frame, and other structural parts that fix these components. The rotor consists of the rotor core (or magnetic poles, yoke), windings, retaining rings, centering rings, slip rings, fans, and shafts. Bearings and end covers connect and assemble the stator and rotor of the generator, allowing the rotor to rotate within the stator, cutting magnetic flux lines to generate induced electromotive force. This is led out through terminal blocks and connected to the circuit, thereby generating current.

General Electric electrical component classification

Fiber optic connectors can be divided into common single-mode and multi-mode connectors for silica-based fibers, as well as other fiber optic connectors using plastic etc. as the transmission medium, based on the transmission medium. According to the connector structure, they can be classified into: FC, SC, ST, LC, D7, DIN, MU, MT, and other forms. Among them, ST connectors are typically used at the cabling equipment end, such as fiber patch panels and fiber modules; while SC and MT connectors are typically used at the network equipment end. Based on the fiber end-face shape, they are classified into FC, PC (including SPC or UPC), and APC; based on the number of fiber cores, there are single-core and multi-core (such as MT-RJ) types. Fiber optic connectors are widely used and come in many varieties. In practical applications, we generally distinguish them based on the different structures of the fiber optic connectors.
