What is the bearing capacity of shear bolt connectors?

Shear bolt connector BLMT-T-25/95-13 is a mechanical connector commonly used for conductor connections in power transmission lines or between wires and other equipment. Its design principle is that the bolt will shear and break under a certain load, thereby playing a certain protective role, preventing excessive external force from being transmitted to the cable or equipment, and reducing the risk of accidents.

Basic principle of shear bolt connector

The shear bolt connector bears and transmits shear force through the interaction between the bolt and the connecting plate. When the structure is subjected to external force, the stress state of the bolt is mainly manifested as shear force, that is, the bolt bears interaction force on the shear surface. The load-bearing capacity of the connector is directly related to the maximum shear force it can withstand, which is usually determined by theoretical calculation and experimental testing.

Factors affecting the load-bearing capacity of stepless shear bolt connectors

1. **Material strength**:

The material of the shear bolt is usually high-strength steel, and its shear strength is the main factor determining the load-bearing capacity of the bolt. The higher the shear strength of the material, the stronger the load-bearing capacity of the bolt.

2. **Bolt diameter**:

The diameter of the bolt directly affects its shear area. The larger the diameter, the larger the shear area and the greater the shear force that can be borne. Therefore, when designing, it is necessary to select bolts of appropriate diameter to meet the load requirements.

3. **Connection plate thickness and material**:

The thickness and material of the connection plate also affect the load-bearing capacity of the bolt. Thicker connection plates and high-strength materials can provide better support, thereby improving the shear strength of the overall connection.

4. **Installation quality**:

The installation quality of the bolt, including preload, hole diameter and bolt diameter fit, etc., will affect the load-bearing capacity. Correct installation can effectively improve the shear load-bearing capacity of the bolt.

5. **Working environment**:

Environmental conditions such as temperature, humidity, corrosion, etc. can also affect the performance and load-bearing capacity of the bolt material. For example, high temperature environments may cause material strength to decrease, while corrosive environments may accelerate the aging and fracture of the bolts.

The load-bearing capacity of the copper bolt mechanical lug is an important factor in determining the safety and performance of the structure. By selecting the right material, diameter, connection plate and ensuring high-quality installation, its load-bearing capacity can be effectively improved. In practical applications, through reasonable design and strict construction management, the bearing capacity of the shear bolt connector can be fully utilized to ensure the safety and stability of the structure.
