nomencl doesn't renew nomname with russian language

Question

I'm trying to renew \nomname in nomencl package with russian language, but it still default value.

\documentclass{article}
\usepackage[utf8]{inputenc} 
\usepackage[russian]{babel} 

\usepackage{nomencl}
\makenomenclature

\renewcommand{\nomname}{Список обозначений}

\begin{document}
    \mbox{}

    \nomenclature{$c$}{Скорость света в ваккууме}
    \nomenclature{$h$}{Постоянная Планка}

\printnomenclature
\end{document}
