Composite pillar insulators have good corrosion resistance and anti-aging properties, and we all know that composite insulators are composed of three parts: flame retardant insulation core rod, flame retardant silicon rod rubber umbrella cover and connecting fittings at both ends. It is the advantages of composite insulators that make it widely used in today's life. Flame retardant insulation mandrel is short for epoxy glass fiber drawing rod, which is the skeleton of composite insulator.
It has multiple effects such as supporting umbrella cover, internal insulation, connecting both ends of the fittings, and accepting mechanical load. It has high tensile strength, generally up to more than 600Mpa, which is 2 times that of ordinary steel and 5 to 8 times that of porcelain, and has excellent dielectric function and chemical erosion resistance, as well as excellent resistance to bending fatigue, creep and impact resistance. Flame retardant silicone rubber umbrella cover has the characteristics of fire prevention, light weight, small size, not easy to break, high tensile strength, strong pollution function.
Different types of flame retardant silicone rubber insulators have different effects, the structural height and creepage interval are also different, flame retardant silicone rubber insulators are mainly used in substations, with excellent hydrophobicity, anti-aging, leakage resistance and electrical corrosion resistance, with high tensile strength and bending strength, its high mechanical strength, impact resistance, shock-proof and anti-brittle function. Light weight, convenient equipment protection, the upper and lower end of the equipment standards and the corresponding porcelain pillar insulator equipment standards are the same, can be used interchangeably.
The composite pole insulator can effectively use the narrow corridor open pressure power supply, can reduce the height of the pole tower, can save a lot of manpower, material and financial resources, because of its high bending strength, can prevent the simple occurrence of cascade cracking of porcelain cross arm, is the porcelain cross arm can not replace the product; Small size, light weight, shock-proof, strong impact resistance, no need for manual cleaning, for safe operation supply guarantee.
