1.Light weight

2.Impact and vandal resistant

3.High pollution resistance

4.Low profile - makes them less environmentally obtrusive

5.Flameproof

6.A wide range of substrates and end fittings

7.Many direct replacement products to obviate the need to re-tension lines after replacement of traditional insulators
