Marine cable BLMT mechanical cable lugs with shear bolts and Mechanical shear-head connectors : key components of Marine communications

With the increasing demand for global communications, submarine cables (submarine cables) play a vital role as an important communication infrastructure connecting continents. Submarine cable systems not only need to withstand the harsh conditions of the deep sea environment, but also must ensure the stability and reliability of signal transmission. In a submarine cable system, BLMT mechanical cable lugs with shear bolts and Mechanical shear-head connectors  are two key components that play an important role in the connection and protection of cables. In this paper, the function, structure and application of torsion terminal and torsion splice tube of submarine cable in Marine communication are introduced in detail.

First, the function and structure of the cable torsion terminal

1.1 Functions

BLMT mechanical cable lugs is an important connection component in the submarine cable system, which is mainly used to connect the conductor and terminal equipment of the submarine cable. Its main functions include:

Electrical connection: Ensure the electrical connection between the cable conductor and the device to ensure the continuity of signal transmission.

Mechanical fixing: Provide mechanical support to prevent the cable from displacement or damage due to external forces such as currents and tides in the deep-sea environment.

Waterproof seal: prevent seawater from penetrating into the interior of the cable, protect the insulation layer and conductor of the cable from corrosion.

1.2 Structure

The BLMT mechanical cable lugs usually consists of the following parts:

Conductor connection parts: Made of highly conductive materials (such as copper or aluminum) to ensure the reliability of electrical connections.

Insulation layer: wrapped around the conductor to prevent electrical short circuit and leakage.

Waterproof sealing layer: Rubber or silicone material is usually used to ensure the waterproof performance of the joint.

Mechanical fixing device: including bolts, nuts, etc., used to fix cables and terminal equipment.

Second, the function and structure of the torque connection tube

2.1 Functions

The Mechanical shear-head connectors is a component used to connect two submarine cables. Its main functions include:

Cable connection: The conductors of two cables are connected together to ensure continuous transmission of signals.

Mechanical protection: Provide mechanical support to prevent the connection from being broken or damaged due to external force.

Waterproof seal: prevent seawater from penetrating into the connection and protect the internal structure of the cable from corrosion.

2.2 Structure

The torque splice tube usually consists of the following parts:

Conductor connection part: made of highly conductive material to ensure the reliable connection of two cable conductors.

Insulation layer: wrapped around the conductor to prevent electrical short circuit and leakage.

Waterproof sealing layer: Rubber or silicone material is usually used to ensure the waterproof performance of the connection.

Mechanical protective layer: Usually metal or high-strength plastic material to provide additional mechanical protection.

Third, the application of torsion terminal and torsion connection tube of submarine cable

3.1 Marine communication system

In the Marine communication system, the cable torsion terminals and torsion splice tubes are widely used in the connection and protection of submarine optical cables and power cables. They ensure the stable transmission of signals and power and are an integral part of Marine communications systems.

3.2 Marine energy development

In the development of Marine energy, such as the development of offshore wind power and submarine oil and gas fields, cable torsion terminals and torsion coupling tubes also play an important role. They are used to connect submarine cables and offshore equipment to ensure a stable supply of power and reliable transmission of signals.

3.3 Marine scientific research

In Marine science research, cable torsion terminals and torsion splices are used to connect various ocean observation equipment, such as seabed seismometers and Marine environment monitors. They ensure the continuity and accuracy of observation data and provide important support for Marine scientific research.

Fourth, future development trend

With the continuous development of Marine communication and energy development, the technology of Marine cable torsion terminals and torsion splice tubes is also improving. In the future, these components will evolve in the following directions:

High reliability: Through the use of new materials and new processes, improve the reliability and durability of components.

Intelligent: Integrated sensors and monitoring systems to monitor the status and performance of components in real time.

Environmental protection: Using environmentally friendly materials and processes to reduce the impact on the Marine environment.

conclusion

As the key components in Marine communication and energy development, the performance and reliability of cable torsion terminal and torque coupling pipe directly affect the operation of the whole system. As technology continues to advance, these components will play an even more important role in the future, providing more stable and reliable support for global communications and energy development.
