Advantage of Polymer Line Post Insulator
1. The umbrella which made of silicone rubber has the advantages of good water repellency, corrosion resistance, aging resistance an so on. It can effectively prevent the occurrence of pollution flash accidents, reduce manual cleaning, and avoid zero-value maintenance, which provides a reliable guarantee for the safe operation of transmission lines.
2. The rod core is made of glass fiber reinforced resin rod and has high tensile strength (>1100Mpa), which is about 1.5 to 2 times that of ordinary steel and 3 to 5 times that of porcelain.
