The Industrial Machinery Division (IMD)工业机械分会 ELECTRIC CURRENT ABROAD电流委员会 1997 Edition (Revised*) CONTENTS Introduction Key To Terms Used所用术语 Plugs in Domestic and Commercial Use (Figure)家用和商用插座 Types of Plugs Used Abroad (Table)国外插座类型 Characteristics of Electric Current Abroad (Table)国外电网特征 INTRODUCTION To assist U.S. manufacturers, exporters and individuals living or traveling abroad, this publication lists the characteristics of electric current available and the type of attachment plugs used in most countries. It is an update of a similar handbook published in 1991. The tables indicate the type of current (alternating or direct current), number of phases, frequency (hertz), and voltage, as well as the stability of the frequency and the number of wires to a commercial or residential installation. This information pertains to domestic and commercial service only. It does not apply to special commercial installations involving relatively high voltage requirements or to industrial installations. 为帮助美国制造商、出口商和旅居国外人士，本文列出了大多数国家所用插座及电网的特征，是对1991年版的相似手册的更新，本表列出了家用电器或商用电器的电流类型（交流或直流），相数，频率(赫兹)，电压，频率的稳定性，线数。这些信息只用于商用电器和家用电器，不适用于有高压要求的特别的商用电器或工业设备。 For most countries listed here, two nominal voltages are given. The lower voltages are used primarily for lighting and smaller appliances, while the higher voltages are used primarily for air conditioners, heating, and other large appliances. Travelers planning to use or ship appliances abroad should acquaint themselves with the characteristics of the electric supply available in the area in which the appliance is to be used. In some cases, a transformer may be used to correct the voltage. However, if the appliance requires exact timing or speed and if the frequency of the foreign electricity supply differs from the one the appliance was designed for, it is advisable to use an appliance designed for the foreign frequency since auxiliary equipment to change frequency is bulky and expensive.
