Non-Earthing Voltage Transformer NOL-NTZ-15(20)-IV for Open Distribution Systems

Nearthed voltage transformers NOL-NTZ outdoor installation are designed for installation in open switchgear (ORU) 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 transformer housing is made of a compound based on cycloaliphatic resin, which is both the main insulation and protects the windings from mechanical and climatic influences.
