Line post insulators are used on overhead distribution lines operating at and below 69KV. These insulators are commonly installed on metal, concrete or wooden structures to horizontally or vertically support the line conductor. Also, these insulators can be used to support high voltage conductor jumpers or leads.
The umbrella which is made of silicone rubber has the advantages of good water repellency, corrosion resistance, aging resistance and 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.
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.
