Heavy duty wire with mixed metals (x6 stainless steel and x3 copper strands) for turbo conductivity and long life Superior shock delivery with 46x conductivity of standard poly wire Ideal for use in windy conditions Made from hard wearing UV resistant materials Resistance:* 130 Ohms/km *Resistance refers to the conductivity of the product. Low resistance (i.e. 110 Ohms/km) means higher conductivity (less resistance to the electric pulse means it can travel further down the fence line)
