PR 2003 Gray UVTR is a polyethylene based concentrate which when blended 5% with HDPE and moisture cure systems including Monosil ® , Sioplas ® , and Ethylene Vinyl Silane Copolymers, offers excellent sunlight and tracking resistance.

Application
PR 2003 Gray UVTR blended 5% with the above referenced resins has historically been used as insulation for 5 to 15 KV Spacer Cable and Tree Wire. It has been used extensively as both primary and secondary wire insulation for overhead distribution. The technology is effective in preventing shorts and flashovers should tree branches come into contact with the wires. Most recently, PR 2003 Gray UVTR blended 5% with the above referenced resins has found new application as an insulation for bare high voltage overhead transmission lines as a solution in wildfire prevention. High wind conditions or bomb cyclones have become more common as a result of climate change. When winds approach 60 mph, bare high voltage transmission lines can slap together scattering sparks on underbrush and igniting wild fires. This has been particularly problematic for utilities in the western USA. This technology provides an economical solution when compared to shutting off power or burying large transmission lines underground.
