The product is suitable for power station and disconnecting switch equipment. The insulators have good hydrophobicity, anti-aging properties, tracking and erosion resisting capability. They have ultimate tensile strength and bending strength. Their mechanical strength is high and anti-impulse, vibration proof as well as brittle fracture prevention are good. Their weight is light and the installation is convenient. The installation dimension of the top and bottom is the same as that of porcelain pillar, so they can be replaced by one another.
