Crossarm Pin
The crossarm pin is a vital piece in electrical infrastructure, boasting several key features. Crafted from high-strength materials like durable steel or robust aluminum alloys, it ensures exceptional mechanical stability, withstanding heavy loads from conductors and adverse environmental impacts. Its precisely engineered design guarantees a snug fit with crossarms and insulators, facilitating seamless installation and preventing loosening over time. Resistant to corrosion and wear, it performs reliably in diverse weather conditions, from intense heat to freezing cold.
Crossarm Pin Material Standards
In terms of material standards, for hot-dip galvanized carbon steel crossarm pins, the steel should comply with the relevant provisions of GB/T 700 "Carbon Structural Steel" to ensure that the strength and toughness of the steel meet the requirements.
The hot-dip galvanized layer must comply with GB/T 13912 "Metallic Coverings - Hot-dip Galvanized Layers of Steel Parts - Technical Requirements and Test Methods", and the thickness and uniformity of the zinc layer must reach the specified values to ensure good corrosion resistance.
Crossarm Pin Dimensional Standards
In terms of dimensional standards, the crossarm pin's pin diameter, length, taper and other dimensions should comply with the design drawings and relevant standard specifications. Common dimensional standards refer to the provisions of documents such as DL/T 764.4 "Quality of Electric Power Fittings Manufacturing - Hot-dip Galvanizing of Steel Parts" to ensure the compatibility of the crossarm pin and the connecting parts.
