Cables.
Standards: Generally BS6500 VDE0250 Conductor: Class 5 annealed copper conductors to BS6360 / VDE0295 Insulation: PVC Bedding: PVC Braiding: Tinned Copper Wire Braid (TCWB) Sheath: PVC (Type TM2 to BS7655) Voltage Rating: 300/500V Temperature rating: Flexing -15ípC to +70ípC Static -35ípC to +70ípC
Central loose tube cable contains one tube with 2 - 24 fibers, which is filled with water blocking gel. A water swelling tape is helically wrapped around the cable core. Either aramid yarn or fiber glass is wound around the tube to provide physical protection and tensile strength. The cable is jacketed with PE for water protection purpose. For direct burial, steel wire armour and corrugated steel tape armour are applied with an optional PE
Screen: (overall screen) (indiviudual screen + overall screen) (overall screen + steel wire armour) (individual screen+ overall screen+steel wire armour) Sheath version: pvc/lsf/lsoh
Conductor material: solid plain annealed copper referred to bs6360 Insulation material: cellular high density polyethylene Laying-up: pairs; units Wrapping: polyester tape Filler: petrolatum jelly filled Screen: aluminium foil with overlapping Bedding: polyethylene
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. Roll, box, drum
