There are different Types Of Wires And Cables around us in this highly mechanized world that facilitate electricity conduction. In any electrical equipment, a continuous circuit is formed: Contacts and conductors joined at the terminal. Different Types Of Cable Terminations are used for different contacts.
A continuous cable line must connect the different sections when any wire device is installed. Where the connections occur, those points are the cable terminations.
Role Of Cable Terminations
Various types of Cable terminations are used to make physical and electrical connections between cables and wires and the terminals of equipment or junctions. Cable terminations are a permanent solution for wire-to-wire connections as they can solder the wires together for long-term dependency, which is essential in industrial electrical engineering. Different types of wires and cables are inserted into the holes provided at the end of terminals which are then made to shrink or tighten with a screw to ensure the connection is secured.
At each end of any cable, there are terminal heads. However, these are intermediate if the cable is spliced in the middle. Cable terminations are easy ways to connect or disconnect wires without twisting or soldering them, thus enhancing the safety of equipment and users.
Difference Between Cable Glands and Cable Terminations
The role of cable gland is to render protection to the equipment and prevent contaminants from entering between types of wires and cables connected together. On the other hand, cable terminations are used to connect the cable to the equipment and ensure proper electrical connectivity.
Different Types Of Cable Terminations
- Heat shrink
Heat shrink cable termination is a component of tubing that is shrinkable when exposed to heat.
- Cold shrink
Cold-shrink terminations do not require heat; technicians can remove the supporting cord when installing them. The cord removal shrinks these terminations so that they can take the desired fit when installed.
- Pre-molded/insulated push-on terminals
Pre-insulated terminations contain a metal body like copper or aluminum enclosed in plastic insulation. They come in various types, such as tubular, fork-type, ferrule, and circular. These types of terminations are usually narrow circular rings so that they can fit over the end of stripped electrical cables.
Benefits Of Using Cable Terminations Over Soldered Joints
Cable termination usage is highly recommended in industrial and residential electrical setups for the following benefits:
- Enhanced safety
- Longevity and durability
- Better electric circuit flow and performance
- Easy installation and maintenance
- Reduced risk of corrosion
- Greater electrical insulation
- Quick and easy installation
When Should Cable Terminations Be Used?
Different cable terminations are necessary, and insulation is important for preventing short circuits or electric shocks.

FAQ
1. What is cable glanding and termination?
Cable glanding refers to securing the cable at its entry point into an enclosure, providing mechanical support and strain relief. Cable termination involves properly connecting the cable’s conductors to an electrical device or panel to ensure a safe and efficient electrical connection.
2. Why is proper cable termination important?
Proper termination ensures electrical safety, prevents short circuits, minimizes power loss, and enhances the longevity of electrical installations by reducing wear and tear at connection points.
3. What are the types of cable terminations?
Common cable terminations include:
- Crimped Termination: Using lugs or ferrules for secure connections.
- Soldered Termination: Using solder to join conductors for a permanent connection.
- Bolted Termination: Using mechanical fasteners for heavy-duty connections.
- Heat Shrink Termination: Using heat shrink tubing for insulation and protection.
4. How do cable glands improve electrical safety?
Cable glands prevent dust, moisture, and mechanical stress from damaging the cable entry points. They also provide strain relief, ensuring the cable remains securely fastened and does not pull loose over time.
5. What factors should be considered when selecting a cable gland?
Key factors include:
- Cable type and size to ensure a secure fit.
- Environmental conditions (e.g., water, dust, chemicals) to select the right material (e.g., brass, stainless steel, nylon).
- Explosion-proof requirements for hazardous areas.
- Ingress Protection (IP) rating to determine resistance to dust and moisture.
