Composite Cross arm Insulator,Polymer Cross arm Insulator
Advantages of polymer crossarm insulator: Nowadays, in distribution line the polymer crossarm insulator always was considered to use since it has many advantages for power line. 1. Increase the mechanical strength 2. Reduces weight 3. Increase corrosion resistance 4. Increase its life span 5. Decrease single phase to the ground fault rate Reduce cost and decrease pole top fire: Composite cross arm insulator acts as the role of cross arm and insulator. Use polymer crossarm insulator, it don’t need cross arm, so this can save some cost. And nowadays there are many countries and areas still use wood cross arm. This has the biggest and most dangerous challenges facing the utility industry is the risk of pole top fire. More and more utility companies using composite cross arm insulator to decrease the risk of pole top fire. We can produce polymer crossarm insulator from 15kV to 132kV, the widely recognized voltage class includes: 15kV, 25kV, 35kV, 69kV, 132kV. If customers have other using requirement, we can also redesign composite cross arm insulator to match the technic requirement. And IEC61109 is still the main standard China composite insulator manufacturer reference to.
