These
cables are intended for use in fixed installations in industrial
areas, buildings and similar applications , where maintenance of
power supply during a fire for 3 hours at 950oC. The
cables are non-armoured fire-resistant cables with thermosetting
insulation and LSNH oversheath and of rated voltage 450/750V and low
emission of smoke and corrosive gases when affected by fire in
accordance with BS 7211:1998, and the cables also fulfill the CWZ
requirements of BS 6387:2013.
安裝在發生大火時需要低煙無毒場所,適用於人煙稠密的場合,該電纜可抵受 950oC達3小時 |
