Different types of composite silicone rubber bushings have different functions, with varying dry arc distances and creepage distances. Composite Post insulators are primarily used in substations and offer excellent hydrophobicity, aging resistance, resistance to leakage current tracking, and resistance to electrical erosion.
They possess high tensile strength and bending strength, with excellent mechanical strength, impact resistance, shockproof performance, and resistance to brittle fracture. Additionally, these Composite Post Line Insulators are lightweight, easy to install and maintain. The installation dimensions at both ends are the same as those of the corresponding porcelain bushing insulators, allowing for interchangeable use.
