JRLX/T (ACCC) Composite lead

Product Description:

Application: Lead JRLX/T has been designed specially for aerial electricity transportation and supply circuitry.  
Advantages of using carbon fiber composite core aluminum twisted wire for transporting and supplying electricity:
●The carrying capacity is twice as that of the common aluminum twisted wire with steel core, but a new wire can be spanned without rebuilding the pole and tower. The section area of aluminum lead in the carbon fiber composite core aluminum twisted wire is 29% more than that of the aluminum twisted wire with steel core.
It can be available at 200℃, while the using temperature for common aluminum twisted wire with steel core is just 100℃.
●In fact the arc drop is removed and it will be not influenced by the long-time creep of aluminum.
●It can be installed easily by simple way, tool and aurum tool and do not need special tool or special training.  
●The construction cost can be reduced by using fewer pole, tower. The span between the pole and tower can be enlarged with high intension to reduce more than 20% pole, tower.
●It has good performance to defense the environmental degradation. It does not rust or corrode and will not have an electrolysis reaction with aluminum lead or other components; it can be cyclic used.
●It can be helpful to reduce the operating cost with high operating efficiency and meet the transmission standard.
Wire loss can be reduced by 29% in the same capacitance capacity, so the content of electricity generation can be reduced and energy sources cost can be saved.
