Excellent electrical insulation performance: The 55-2 pin insulator has a withstand voltage of 70kV under power frequency, and a positive impulse flashover voltage of 70kV. The dense porcelain glaze layer on the surface does not accumulate charges easily, effectively resisting corona and arc, and maintaining stable insulation effect in both high and low voltage fields, significantly reducing the risk of line leakage.
Stable mechanical load-bearing capacity: The cantilever strength is 11kN, which can effectively withstand multiple mechanical stresses such as the weight of the conductor, outdoor wind load, and ice load. The connection structure between the glued zinc sleeve and the steel foot is firm, resistant to vibration and impact, and suitable for the complex mechanical usage environment in the outdoors.
Standardized design with high adaptability: It fully complies with international common ANSI and IEC standards, and the structural dimensions are matched with mainstream power line accessories. Installation does not require special tools, and it can be directly replaced with products of the same specification. At the same time, it supports customization of white, brown, etc. glaze colors to meet the needs of different projects.
