This product is used for AC 50 Hz rated voltage 0.6/ikV and below fire and emergency light system transmission and distri-bution lines.

Ng-A (BTLE) is a flexible mineral insulating cable replaced by a copper pipe cover to an aluminum pipe cover.

This product is used for AC 50Hz rated voltage 0.6/1kV and below fire emergency system transmission and distribution lines.

(1) Cable conductor: made of high conductivity metal copper as conductor. (2) insulation layer: The use of high temperature resistant, non-burning inorganic magnesium oxide as insulationmaterial. (3) Metal sheath: The use of copper pipe as a sheath, after special processing has good continuity and bending characteristics, and can beused as a grounding wire. (4) Outer protective layer: if necessary, squeeze a layer of plastic outer protective layer outside the metal copper sheath, the use of low-smokenon-toxic plastic material, with good protection Corrosion characteristics.
