Fillers shall be used in the interstice of the multi-core conductor cable where
necessary to give the complete cable a subsfantially circular croos section.
Fillers shall be of polypropylene, non-hygroscopic materials.
Fire Resistant Cable (FR)
Fire Resistant (FR)cables with the cable size of 6mm² or less, or branch
circuit wire such as emergency circuits shall be single sheathed and installed
in conduit or trukings. FR cable with sizes larger than 6 mm shall be XLPE
insulated and sheathed with fire resistant or fire retardant, low smoke ze
halogen material.
Outer sheath shall be of polyethylene or other material that have low smoke
and zero halogen (LSF or LSFOH). For multi-core cable spacing between
conductors shall be filled with filler.
Rated voltage of cable shall be 0.6/1 kv
These cables shall be resistant to flame temperature of 950°C for 1 hour
minimum and water spray as defined in BS6387
Cable shall not generate corrosive gases in when burnt.
Standard for Testing of Fire resistance shall be conforming to BS6387
Category C, W and Z.
Standard for Testing of Flame Retardant shall be conforming to IEC 60332-1
Standard for Testing of Low Smoke shall be conforming to IEC 601034-3
The Contractor shall submit the test report for approval.
Control Cable (CVV and CVVs)
All control cable shall be suitable for installation in wet and dry locations. The
conductor shall be of soft or annealed strand uncoated copper wire.
The insulation shall be polyvinyl choride (PVC) or polyethylene(PE) suitable
for use on a copper conductor with a maximum operating temperature not less
than 70 ºC
Fillers shall be used in the interstice of the mul-ti conductor cable where
necessary to give the complete cable a substantially circular cross section.
Filllers shall be Polyvinyl choride (PVC) rod or Polyethylene (PE)
The cable shall be helically wrapped over the filler and copper shielding with
non-hygroscopic Mylar or Polyester tape.
The shielding, for CVVs cable, shall be annealed copper tape of suitable
width and shall be helically applied with a minimum 10% lap. The annealed
copper tape shall be at least 0.1 mm thickness and substantially free from burrs
The outer sheath shall be of black polyvinyl (PVC) jacket over the wrapping
and shall comply in all respects with ICEA S61-402 standards
