Non-Grounded Voltage Transformer NOL-NTZ-IV for Outdoor Installations and Electrical Systems

NOL-NTZ non-earthed voltage transformers of outdoor installation are designed for installation in open switchgear (OSD) and other electrical installations and are component parts. Transformers provide transmission of measuring information signal to measuring devices, protection, signalling, automation and control devices, as well as insulation control. They are intended for use in commercial and technical electricity metering circuits in electrical installations of the appropriate voltage class. For the railway industry the application of transformers is traction substations, transformer substations and linear devices of traction power supply of railways. Transformers are made in the form of a support structure. The body of transformers is made of compound on the basis of cycloaliphatic resin, which is both the main insulation and provides protection of windings from mechanical and climatic influences.
