范围1.1本标准适用于用作电路连续性装置的封装隔离变压器，根据《加拿大电气规范》第I.1.2部分，该隔离变压器拟安装在机场现场照明串联电路中，用于非危险场所。本标准适用于由缠绕在铁芯上的初级和次级线圈组成的变压器，组件被封装在防水外壳中。初级线圈通过插头/插座连接器连接到串联电路中，次级线圈通过插头/插座连接器连接到灯具导线。连接器的插座部分配备有变压器，以与串联电路和灯具电缆上的插头部分匹配。变压器插座部分可以内置在变压器体内，也可以模制在变压器导线的端部。1.3为满足本标准要求而制造的变压器适用于在最低55°C至最高65°C的环境温度下连续室外运行，并适用于直接土埋。

Scope1.1This Standard applies to encapsulated isolating transformers for use as a circuit continuity device, intended to be installed in airport field lighting series circuits for use in nonhazardous locations in accordance with the Canadian Electrical Code, Part I.1.2This Standard applies to transformers that consist of primary and secondary coils that are wound upon a core, the assembly being enclosed in a waterproof case. The primary coil is connected into the series circuit and the secondary coil to the light fixture lead by means of plug/receptacle connectors. The receptacle portion of the connector is provided with the transformer to mate with the plug portion on the series circuit and light fixture cables. The transformer receptacle portion may be either built into the transformer body or moulded into the ends of transformer leads.1.3Transformers constructed to meet the requirements of this Standard are suitable for continuous outdoor service in ambient temperatures from a minimum of 55 °C to a maximum of 65 °C and for direct earth burial.
