Product Property:
Molecular formula: Zn
Molecular Weight: 65.38
Physical Property: light grey metal fine powder.
Density: 7.14g/cm3
Melting Point: 419.4¡ãC
Boiling Point: 908%
Chemical property: insoluble in water, soluble in acid and alkali, slowly soluble in acetic acid, ammonia water, it has strong reducing performance and give out hydrogen. Lumps when being wet, keeps stable in dry air and generates white basic carbonate covering in its surface in wet air. When combusting in the air, it can generate blue green flame and generate zinc oxide. High pure zinc act slowly with sulfuric acid and nitric acid, while act fast when it contains few of other metals such as steel, tin and lead.
Product characteristics:
The highly active Zinc powder produced by our company has some characteristics of high contain of Zinc, low impurity elements, smooth surface, large surface area, small density of loose-powder, little oxide on surface, melting deformation and little grape shaped particles after sticking, average particle diameter is 0.1-4¦Ìm, total Zinc contain is more than 98.5%, metal Zinc contain is more than 96%.

Applications:
Long distance outside telephone, catv, data, communications.
Installations:
Installed in duct, self supporting (figure 8 self supporting or adss all dielectric self supporting) and direct burial
(with armoring).
Construction:
The cable consists of 5 to 36 elements stranded in up to 3 layers around a central strength member and bound in a
Jacket. The elements are usually fiber containing tubes. However, fillers are also used, when needed to preserve cable
Geometry. Two to twelve color coded fibers are loosely laid in each tubes filled with water-blocking gel.
Technical parameters:
Maximum transmission distance: 6km (single mode); 0.3km (multimode)
Maximum pulling load: 1500-2700 n (short term installation); 900-1500n (long term installation)
Minimum bending radius:
Short term installation: 20 x overall diameter
Long term installation: 10 x overall diameter (non armored); 20 x overall diameter (armored)
Twist (torsion length): 125 x overall diameter
Working temperature: -40íµ ~ +70íµ (pe sheath)
Storage temperature: -50íµ ~ +70íµ (pe sheath)
Product highlights:
All the fiber containing tubes are placed in concentric layers around the central member; through the control of
The twist length, the fiber cable can achieve better pulling load and operating temperature.
Tube materials are water resistant and can sustain high tension. Being filled with special water-blocking gel, the
Tube can provide water protection for the fibers inside the tube.
Central member, which is usually either made of dielectric frp, or solid/ stranded steel coated with polyethylene,
Are placed at the centre of the cables.
í= Applications:
Short and medium distance, indoor and protected environments. Offered as a riser, plenum, or general purpose cable,
it is used for interconnection of distribution boxes, or the distribution boxes and customer equipments, and between
floors.
í= Installations:
Installed along the wall, the roof, interlayer, canal and indoor.
í= Construction:
The cable contains 4 to 72 fibers individually buffered to 0.9 mm in a tight or semi tight construction and coded. The
cable structure depends on the number of fibers: The 4 to 12 fiber cables contain individual fibers without sub-units,In
the 16 to 72 fiber cables the fibers are grouped in the sub-units. In the 4 to 12 fiber cables, the individual fibers are
stranded and protected by aramid yarn and a PVC or LSZH jacket. In the 16 to 72 fiber cables, the fibers are grouped
into sub-units which are laid helically along the cable axis. Each sub-unit contains 4 to 6 fibers, aramid yarn and a
PVC or LSZH jacket. The 72 fiber cable consists of twelve sub-units, nine of them are stranded around a central
element made of 3 sub-units.
í=Technical Parameters:
íe Maximum Transmission Distance: 6km (Single Mode); 0.3km (Multimode)
íe Maximum Pulling Load: 100N(Short Term Installation);60N(Long Term Installation)
íe Minimum Bending Radius:
Short Term Installation: 20 x Overall Diameter
Long Term Installation: 10 x Overall Diameter (Non-Armoured);
20 x Overall Diameter (Armoured)
íe Twist (Torsion Length): 125 x Overall Diameter.
íe Working Temperature: -10íµ ~ +70íµ (PE sheath)
íe Storage Temperature: -20íµ ~ +70íµ (PE sheath)
í= Product Highlights:
íe Small diameter and light weight.
íe The high tension characteristics of the aramid yarn serving as strength member
can offer good stability in the transmission performance.
íe Compact and flexible construction are especially suitable for indoor installations.
íe Tight Buffer fibers are made from fiber rods with good linearity and low extruding output. By careful calibration of
the vacuum pumping equipment, the uniformity of the outer diameter of the tight buffer fibers can be easily achieved
with excellent strip ability.
íe LSZH jackets can be offered for indoor application for which flame retardancy is required.
íe Cutting edge production equipment, good quality materials and optimized process ensure low induced attenuation
within the operating temperature range.
íe Fiber geometry are strictly monitored to ensure superior transmission performance.
