Oil-filled single-phase overhead transformers designed and produced by Chuanli are normally used for stepping utility distribution voltages (ranging from 2400 to 34500 volts) down to lower utilization voltages.
Overview
Oil-filled single-phase overhead transformers designed and produced by Chuanli are normally used for stepping utility distribution voltages (ranging from 2400 to 34500 volts) down to lower utilization voltages. Although some are used for stepping down to commercial and industrial voltages such as 277, 240/480, 2400 and 4800, most are used for stepping down to the single-phase voltage of 120/240.
These transformers are also used for small substations, miscellaneous applications and can serve to step up voltages.
The transformer type describes the basic protective devices which are included as an integral part of the transformer package. Table I defines each type as a function of the protective device(s) included. These protective devices and their functions are described later in this section
