NHXMH 300/500V (N)HXMH 300/500V

Installation cables with XLPE insulation and halogen-free plastic coating.

Installation cables with crosslinked polyethylene insulation and a sheath of halogen-free thermoplastic material, with low fumes and corrosive gases emission during combustion. Designed for installation in buildings with stricter fire protection requirements. Designed for permanent installation in power and lighting installations, for laying in dry and damp rooms above, under and under plaster, in masonry and concrete, except for direct deposition in single-fraction concrete, vibrated and whipped concrete.
