Explore Top Double Arming Bolt

A double arming bolt is a specialized bolt used in the utility and electrical distribution industry. It attaches two sets of crossarms to a utility pole to provide extra support and stability for electrical power lines. A double arming bolts is also known as a double-end bolt. It consists of a long-threaded rod with a curved or bent center section. This section allows for the double arming bolts to fit around the utility pole while the threaded ends secure the crossarms. It also helps distribute the weight and tension across the utility pole to reduce stress on individual components. A double arming bolts is from materials such as steel or galvanized steel. This materials are able to withstand outdoor conditions and resist corrosion.

Components of a double-end bolt

A double arming bolt consists of several components working together to provide stability and support. The components ensure secure attachment of crossarms. The following are the main components of a double arming bolt.

• Threaded rod – this is the main body of the double-end bolt that provides the means for attaching the crossarms and securing them to the utility pole.
• Curved section – the curved section in the middle of the rod allows it to wrap around the utility pole. It holds the bolt in place and provide clearance for attaching the crossarms.
• Threaded ends – the threaded portions on both ends enable the attachment of nuts for secure connections.
• Nuts – nuts help to secure the crossarms to the double arming bolt to tighten and hold the crossarms firmly in place.
• Crossarms – crossarms are the lateral beams mounted to the utility pole. They provide support for electrical power lines and other equipment.

Types of double arming bolts

There are two main types of double arming bolts which include the all-threaded and double-threaded double arming bolts. These two main types mostly work in transmission lines and telecommunication lines respectively. Also, there are other types of double-end bolts designed to meet various pole configurations. They are as discussed below.

1. Standard double arming bolt – this bolt consists of a straight threaded rod with a curved section to fit around the utility poles. The threaded ends secure two sets of crossarms with nuts.
2. Offset double arming bolt – this has a slight bend in the threaded rod which allows the crossarms to position at an angle from the utility pole.
3. Short shank double arming bolt – these bolts have a shorter threaded section than standard bolt. They are mostly used with utility poles with limited space.
4. Extended double arming bolt – these bolts have longer threaded sections than standard bolts. This is to provide more flexibility in positioning the crossarm on the utility pole.
5. V-shaped double arming bolt – these bolts have a V-shape in the center section of the threaded rod. This is to allow the bolt to fit around the corner of the utility pole.

Applications of double-end bolts

Double-end bolts find use in various applications in the utility and electrical distribution industry. They ensure stability and reliability of electrical power distribution systems. They also provide secure and durable connections between utility poles and crossarms. This allows efficient power line distribution and supporting various electrical and communication services. The following are the common application areas of double end bolts.

1. Transmission and distribution towers – these bolts work where multiple crossarms are necessary to support numerous high-voltage lines.
2. Corner bracing – V-shaped double arming bolts for corner bracing provide the necessary corner bracing. This is in cases where a pole supports power lines at a right angle.
3. Streetlighting – the bolts help to hold and support the crossarms that support streetlight fixtures on utility poles.
4. Power line distribution – the double end bolts also attach multiple crossarms to a single utility pole. They provide support for multiple power lines.
5. Obstruction clearance – offset double arming bolts for obstructed power line configurations work where extra clearance is necessary for power lines or other equipment.
6. Crossarms extensions – double arming bolts with extended threaded sections help to attach larger or additional crossarms to allow for increased capacity for more power lines.
7. Telecommunication infrastructure – the bolts help to mount crossarms that hold telecommunication cables and equipment on poles.

Installation guide for double arming bolts

Installation process of the double arming bolts involves attaching two sets of the crossarms to a utility pole. This is to provide support for power lines and other equipment. Follow all the safety procedures and protocols when working with utility poles. Additionally, it is important to seek guidance from experts if unsure or inexperienced for safe installations. The following is a basic installation procedure for the double arming bolt.

1. Ensure you have the correct size and type of double arming bolts and crossarms for the utility pole you are working on. Check for any damage of defects before installation.
2. Determine the location on the utility pole where you need to install the double arming bolts to hold the crossarms.
3. Place the crossarms on each end of the double arming bolts and ensure they are perpendicular to the utility pole.
4. Install the nuts and washers and ensure the nuts connect correctly and securely tightened.
5. Tighten the nuts on each end of the bolt to secure the crossarm in place and ensure the crossarms are level and evenly tightened.
6. Check the installations to confirm their stability and make any necessary adjustments. This is to ensure a secure and even attachment.

Selecting the best double arming bolts

The selection process of the double arming bolt involves considering various factors. These factors ensures it meets the specific requirements of your utility pole. The selected double arming bolt should match to your specific requirements to ensure a secure and efficient installation. This enhances the stability and reliability of your utility pole and electrical distribution system. The following are the several factors to consider when selecting the double end bolts.

1. Consider the overall cost of the double arming bolt and balance the cost-effectiveness with quality and performance.
2. Determine the type and design of double arming bolt that best suits your application.
3. Ensure the double arming bolts’ thread size matches the crossarm’s mounting holes and the pole’s size.
4. Consider the load capacity of the double arming bolt to ensure it can safely support the weight of the power lines.
5. Ensure the double arming bolt is compatible with the size and type of crossarms you intend to use.
6. Select the bolts made from durable materials like steel to offer enhanced corrosion resistance for outdoor installations.
7. Verify that the selected double arming bolt meets all the relevant safety regulations and industry standards.
8. Choose double arming bolts from reputable manufacturers known for producing high quality and reliable products.
