1. An ultraviolet (UV) and heat "Do no UV protection ACSR conductor for direct sunlight environment temperature ACSR conductor in a metal conduit or raceway is high, many polymeric materials in this temperature will reduce the use of life.
2. Water and mechanical damage (repair costs) "in the LAN twisted-pair ACSR conductor water will increase the capacitance, thereby reducing the impedance and causing near-end crosstalk problems. Cable repair is very expensive, in every interruption termination point at least twice.
3. Grounding, and the total length of the route (not merely between floors). "If the ACSR conductor shield needs grounding, you must comply with the appropriate standard. Room building using outdoor grade twisted pair LAN wire and cable, the total length should be limited to 90 meters for 100Mps or 1000Mbps network, its distance can not exceed this limit laid as laid distances between 100 meters to 300 meters, you should choose the cable.
