I Product Details
BTTW/YTTW Metal Sheathed Inorganic Mineral Insulated Cable
Flexible fireproof cable and copper sheath embossing mineral
insulated cable. The cable is a new fireproof cable defects based
on modified insulated cables in mineral, it can overcome the
disadvantages of mineral insulated cable production is limited by
the length of the middle joint installation, avoid appearing in
question, has the advantages of the insulation layer is not easy to
damp, installation convenience, with the continuous promotion of
the product excellent performance, they are increasingly affected
by the broad masses of customers, it has been widely used in
industrial and civil construction.
II Properties
Fireproof performance, fire resistance rating will not only meet
the national standard GB12666.6A 950 degree Celsius, 90min, but
also to meet the provisions of the United Kingdom BS6387-1994 A
Grade of 650 degree Celsius 3H; B 750 degree Celsius 3H; C 950
degree Celsius 3H requirements; At the same time, in the combustion
can tolerance water spray and mechanical impact; 2, continuous
length, whether it is single core, or multi-core cable, its length
can satisfy the power supply need of length, above each continuous
lengths up to 1000m; 3, section of a large, single core cable
section is 630mm2, multicore cables up to 70mm2; 4, with flexible,
cable disc in the disc, the bending radius is 6-10D; 5, burning
smoke-free non-toxic using inorganic materials, insulation, does
not produce any harmful gas during burning, no 2 pollution, is the
real green environmental protection products; 6, the overload
capacity is large, the cable ampacity not only large, but also has
large overload capacity. According to the wiring to be shown,
usually cable surface temperature ≤ 70 degree Celsius, if the
wiring can not touch, nor with the combustible materials in
contact, cable sheathing temperature up to 105 degree Celsius.
Overload fireproof cable long-term working temperature can reach
250 degree Celsius 7, corrosion resistance, good shielding
property, the copper sheath good corrosion resistance, in
particular or corrosion of the copper environment, should be
applied a layer of low smoke zero halogen or plastic external
protecting layer on the copper sheath. In the shielded copper
sheath, no electromagnetic interference, have not the signal,
control cable transmission information interference 8, good safety,
fire cable to normal power supply in the flame (normal power supply
950 degree Celsius for more than 3 hours), starting a fire
extinguisher, reducing fire loss. The copper sheath is a good
conductor, grounding is best, greatly improve the sensitivity and
reliability of grounding protection 9, long service life, high
temperature is not easy to aging, in the normal condition, its
service life is more than 100 years. 10, flexible fire-proof cable
transportation, installation, assembly is simple, similar to that
of an ordinary cable, 11, economical, flexible fire-proof cable
because of advanced technology, simple installation, low in the
same conditions the comprehensive cost than mineral insulated cable
charges.
III Scope of Application
Shopping mall, department store, hospital, school, stadium,
exhibition center, train station, airport, subway, commercial
buildings, hotels, places with dense population, iron and steel
enterprises, 100 meters above the building.
