Crossarm Pin Buying Guide

A crossarm pin is a device used to support and mount and secure crossarm to the pole. It is a horizontal wooden or metal beams mounted perpendicular to the utility pole. The pin acts as a platform for attaching electrical insulators, conductors and other equipment. It is typically made of steel or other durable materials. It is available in different designs to accommodate different types of crossarms. A crossarm pin have three parts, the crossarm pin base, a crossarm pin body and the crossarm pinhead. South American power distribution networks require the use of high-quality crossarm pins. This helps them withstand the diverse environmental challenges in the region. The common types of crossarm pins include lag screw, clevis pin, angle pin and shoulder pin. They find use in applications such as crossarm attachments, insulator attachment, conductor support and hardware attachment.

Selection and installation of crossarm pin

Proper selection ensures safe and reliable operation of overhead power lines and utility poles. The selection process includes considering various factors. These include type of crossarm, application, load requirements and environmental conditions. The installation should ensure the stability and safety of overhead power lines. The following is a basic installation guide for crossarm pin.

1. Preparation – gather all the necessary tools required for the installation. These include crossarm pin, utility pole, crossarm, insulators, hardware, safety gear and wrenches.
2. Location – select the suitable location for installing the crossarm pin on the utility pole. Ensure it aligns with the requirements of the crossarm and hardware attached.
3. Utility pole preparation – create a hole for the crossarm pin using a drill on the utility pole.
4. Positioning – place the crossarm in the desired position on the utility pole and ensure it is level and properly aligned.
5. Crossarm installation – insert the threaded end of the crossarm pin through the hole in the crossarm. Ensure proper resting against the crossarm if it has a shoulder.
6. Securing – thread the non-pointed end of the crossarm pin into the hole or threading utility pole. Ensure proper tightness to offer proper support.
7. Insulator and hardware installation – secure the insulators and hardware using suitable fittings.
8. Safety measures – insert the cotter pin through the hole provided on the non-pointed end of the pin. Bend the ends of the cotter pin to secure it in place.
9. Inspection – perform a visual inspection of the installation to ensure the crossarm, insulators and hardware have proper positioning.
10. Documentation – proper documentation provides reference for future reference. It includes dates, types and pictures for the installation.

Maintenance and inspection of crossarm pin

Regular maintenance and inspection of the crossarm pin ensures the continued safe and reliable operation of overhead power lines. The frequency depends on the specific location and environmental conditions. Additionally, it is advisable to conduct professional maintenance and inspection once in a while. The following is a basic guide for the maintenance and inspection of crossarm pins in south America.

• Conduct visual inspections of the crossarm pins and check for signs of wear, damage or corrosion.
• Test the tightness of each crossarm pin by turning it by hand. Tighten any loose connections using the suitable torque levels.
• Inspect the condition of the conductors attached to crossarm pin ensuring no damage.
• Check the adjustment and tension regularly to ensure proper functioning and desired angle and tension maintained.
• Regularly clean the crossarm pin to remove dirt, debris and any corrosion accumulated on the surface.
• Apply lubricant to the threads to help prevent corrosion. This also offers easy adjustments and extend the lifespan.
• Replace any crossarms that show signs of wear, damage or not structurally sound.
