Application
l 1.Laying method: Aerial
l 2.Mainly applied in electric power system to provide a convenient way to establish communication networks. It is suitable for aerial installation when a communication line has to span a river, a valley, a thunder area and other fields with special requirements.
Characteristics
l 1.Large span lengths and the largest span is over 1700m.
l 2.Non-metallic material, with high insulating property performances as well as lightningproof
l 3.Special Anti-Track outer sheath (optional) protection, strong anti-electro-corrosion ability.
l 4.The aramid yarn ensures the cable’s tensile resistance, and also have good bulletproof performances.
l 5.Light weight with small diameter, reducing the load caused by ice and wind as well as the load on the towers and backprops.
l 6.Can be installed without shutting off the power.
