Composite post insulator has good corrosion resistance and aging resistance. We all know that composite insulator is composed of flame-retardant insulating core rod, flame-retardant silicon rod rubber umbrella sleeve and joint fittings at both ends. It is the advantages of composite insulator that make it widely used in today's life. Flame retardant insulating mandrel is the abbreviation of epoxy resin glass fiber pull-out rod, which is the skeleton of composite insulator.
It has multiple effects such as supporting umbrella sleeve, internal insulation, connecting hardware at both ends, and accepting mechanical load. It has high tensile strength, which is generally more than 600MPa, twice that of general steel and 5 ~ 8 times that of porcelain. It also has excellent dielectric function and chemical corrosion resistance, as well as excellent bending fatigue resistance, creep resistance and impact resistance. Flame retardant silicone rod rubber umbrella cover has the characteristics of fire prevention, light weight, small volume, not easy to break, high tensile strength and strong pollution function.
Different types of flame-retardant silicone rubber insulators have different effects, and their structural height and creepage interval are also different. Flame retardant silicone rubber insulators are mainly used in substations. They have excellent hydrophobicity, anti-aging, resistance to electric leakage and tracking, and resistance to electric corrosion. They have high tensile strength and bending strength. They have high mechanical strength, good impact resistance, shock resistance and brittle fracture resistance, light weight and convenient equipment protection, The equipment standard of its upper and lower ends is the same as that of the corresponding porcelain post insulator, which can be used interchangeably.
Puncture type lightning protection pin insulator composite post insulator composite cross arm insulator can effectively use the narrow corridor to turn on voltage and power transmission, reduce the height of the pole and tower, and save a lot of manpower, material and financial resources. Because of its high bending strength, it can prevent the cascade cracking accident of the porcelain cross arm, which can not be replaced by the porcelain cross arm; The utility model has the advantages of small volume, light weight, strong shock resistance and impact resistance, and does not need manual cleaning, which provides guarantee for safe operation.
