产品详情

耐火控制电缆NH-KVV NH-BV NH-BVV耐火电缆
Fire Resistant Cable耐火电缆耐火控制电缆NH-KVV NH-BV NH-BVV本产品适用于高层建筑、油田、电站、电厂、矿山、化工、地
铁等要求防火条件高的场合,也时应急电源、消防泵、电梯通
讯信号系统的应备电缆。该产品具有较高的耐火能力,在经受
火焰直接燃烧情况下,在一定的时间内(不小于3h)不发生短
路和断路故障,确保继续供电以维持照明和传输信号,保护人
员有足够的时间安全撤离,且有利于灭火和减少损失。
It is used in the environment with high demand on
?re resistant performance such as high-rise building, oil
?eld, power station, power plant, mine, chemical industry,
subway and so on. It is also necessary cable prepared
for emergency power, fire-flight pump and communication system for elevator. In time of being directly ?red by
flame, it could endure continually supplying power and
transmitted signal to keep lighting within certain time (no
less than 3 hours) for people to retreat safely and also to
bene?t ?ghting ?re to lower damage.

series:450/750V; Bseries450/750V)
2: Max temperature of long term working is
70℃&105℃ for ?ame retardant cable with PVC insulation
and 90℃ for cable with XLPE insulation.
3: Temperature for installation is no lower than 0℃.
4: Recommended bending radius for installing: ≥40D
for power cable with single core; ≥30D for power cable
with multi-core; ≥12D for control cable.
B series plastic wire: ≥4D(D<25mmw);≥6D
(D≥25mm)
Note: D means outer diameter

五、Technical Performance。
1: Electric performance and mechanical & physical
performance of cable is the same to common cable in
similar category.
2: Current-loading capacity of cable is the same to
common cable in similar category.
3: Fire resistant performance shall meet the requirement of GB/T19666-2005 standard. 3A fuse wire won’t
break during burning test period.
4: Out diameter of ?re resistant cable with cross section 25mm
2
or lower is bigger than that of common cable
by 15%. Out diameter of fire resistant cable with cross
section more than 25mm
2
is bigger than that of common
cable by 25%.
六、 Cautions
1: Four layers of mica tape should be wrapped
around between insulation and conductor as ?re resistant
layer in connection of cable. Other installing measures
may be taken according to that for similar type cable.
2: User should strictly avoid damage on cable with
sharp-edged objects. Otherwise it would affect ?re resistant performance of cable.
七 Delivery length
Delivery length of cable depends on both agreements
with length error allowance of ±0.5%
