Description

AOPS has been designed to provide reliable insulation and protection on bare overhead line systems preventing electrical outages caused by accidental contact from trees, animals and other objects. Outages may also occur in windy conditions between power lines and when these lines are close to steel structures.

 

Features

  • Suitable for voltage up to 35kV
  • Prevent tapping by hooking and other means
  • Excellent UV and abrasion resistance properties resulting in outstanding resistance to weathering (harsh environments)
  • Erosion and tracking resistant
  • Quick and easy installation
  • Installation on live installation by means of specially designed tools
  • Red mastic sealant available for improved performance
  • Colours – red / yellow / green / black
