Gemini twisted paired cables are best suited for telephone and switchboard cabling applications. The cables can be used for switchboard and internal telephone wiring in apartments, high-rise buildings, offices, factories. hotels, residential complexes, etc. The most common sizes are 2 Pair, 3 Pair, 4 Pair and 5 Pair in conductor of 0.4 mm or 0.5 mm.
Low Power Loss
Low Crosstalk
Fire Retardant Sheath
Low Attenuation
1 Pair to 20 Pair(0.4mm / 0.5mm)
Conductor : The Central Conductor is made of bare annealed solid electrolytic grade of copper
Insulation : Premium quality HDPE is used. This Server for low attenuation and minimized cross talk
Twisted Pairs : The cores are carefully twisted with suitable lays and bunched together
Packing : Available in 90 meter and 500 meter. higher lengths available on special request.
