求翻译：变压器的型号通常由表示相数、冷却方式、调压方式、绕组线芯等材料的符号，以及变压器容量、额定电压、绕组连接方式组成。是什么意思？

Transformer models are usually represented by a number of phases, cooling mode, the regulator mode, winding wire core materials such as symbols, and transformer capacity, rated voltage, winding connection components.

Models with the transformer is usually expressed by several, cooling method, type of voltage regulation, winding the wire core materials such as symbols, as well as transformer capacity, rated voltage, electrical windings connect composed manner.

Power factor big and small and circuit load nature related, like resistance load and so on incandescent lamp bulb, resistance furnace power factors are 1, generally has the inductive load electric circuit power factor all to be smaller than 1.The power factor is an electrical power system important

Transformer models, usually by the number of phase, cooling system, regulating, winding core materials, such as symbols, and composed of transformer capacity, rated voltage and winding connection way.
