Cable Jointing and Termination
Cable Jointing and Termination” refers to methods and techniques for joining and securing electrical cables, as well as for connecting cables to equipment or equipment: distribution, telecommunications, mechanical equipment, etc. Cable is proper termination is essential for ensuring reliable and safe electrical connections Here are some helpful tips:
Cable Jointing:
Cable Joint requires a secure and reliable connection between two or more lines. This is done to extend cable lengths, repair damaged cables, or join cables of different sizes or thicknesses. The objective is to maintain the electrical mechanical integrity of the cable and to eliminate the risk of electrical faults, overheating, and other potential hazards Cable connections can be made using various methods, e.g.
Methods of joining cables:
- Cold shrink joints: Cold shrink joints are designed for easy and quick installation. The joint is pre-stretched and is on a removable tendon. Once over the cable joint, the core is removed, allowing the shrinkage sleeve to slide and secure it. This method eliminates the need for special tools for heating guns, reducing the risk of overheating the blades.
- Heat Shrink Joint: Heat shrink joints apply heat shrinkage to a specially designed tube surrounding a cable joint. The heat causes the tube to contract, creating a tight seal. The temperature used must be controlled to avoid damage to the insulation or bond of the cable.
- Resin-filled joints: Resin-filled eggs are especially effective in harsh environments where moisture and contamination are a concern. The cable joint is housed in a resin-filled housing, which provides excellent protection against moisture, chemicals and physical damage. The resin also acts as a joint insulator and improves the overall mechanical strength of the joint.
- Taped Joints: Taped cells use insulating tape or mastic tape to secure the cable ties. This method is suitable for low voltage and high voltage cables. It is important to ensure adequate pressure and coverage when taping to maintain the required levels of insulation and protection.
Cable Termination:
Cable termination consists of connecting a cable end to a device, device, or termination point. Proper shutdown provides reliable and safe electrical connections while preventing issues such as signal loss, voltage, and overheating. Different finishing methods are used for different materials:
- Crimp Termination: Crimp termination involves attaching a metal connector or terminal to the end of the cable. The cable is inserted into the connector and a crimping tool is used to press the connector into the cable. Proper crimping ensures strong electrical connections and mechanical integrity. Depending on the application and the type of connection, different types of crimps (hexagonal, indented, etc.) are used.
- Compression Termination: Compression terminations are typically used in high-power applications where a strong and reliable connection is required. A compression lug or connector is placed on the disconnected end of the cable, and hydraulic tools are used to compress the connector into the cable, preventing gas leakage and less tension in the cable
- Solder Termination: Solder finishing involves melting the solder on the cable metal and on the terminal or connector. This method provides a stronger and less complicated connection. However, it takes skill and precision to avoid overheating the lines and damaging the insulation.
The importance of proper assembly and completion: Proper wiring and disconnections are essential to maintaining the safety and reliability of electrical systems. Poorly written joints and terminations can cause various issues, e.g. –
Fire Hazard: Poor connections can cause excessive heat and pressure, which can cause a fire.
Voltage Drop: A bad connection can cause a voltage drop, reducing the efficiency of the electrical system.
Signal loss: Failure to disconnect telephone connections and data transmissions may result in signal loss and data corruption.
Equipment Damage: Improper shutdown can damage equipment and tools.
Safety Hazards: Defective connections can cause electric shock and other safety hazards.
