• Application: These are commonly used in power distribution systems to extend the length of a cable or repair damaged cables.
• Features:
  • Ensures continuity of electrical flow.
  • Protected with insulation materials.
  • Suitable for underground and overhead cables.

2.Tee Joint:

• Definition: Tee joints are used to connect three cables, forming a T-shaped connection.
• Application: These are used in branch circuits where one main cable splits into two different paths.

• Features:
  • Provides a secure and reliable connection.
  • Commonly used in lighting systems and distribution boards.
  • Requires proper insulation to avoid short circuits.

3.Duplex Joint:

• Definition: Duplex joints are used to connect two cables with different characteristics or materials.
• Application: These joints are often used when transitioning between copper and aluminum cables.
• Features:
  • Reduces the risk of corrosion caused by material differences.
  • Ensures a strong and efficient connection.
  • Requires specialized tools and materials for installation.

4.Britannia Joint:

• Definition: A Britannia joint is a specific type of cable joint used to join two conductors of the same material and size.
• Application: Commonly used in telecommunication and low-voltage applications.
• Features:
  • Involves twisting and soldering the conductors for strength.
  • Provides excellent mechanical and electrical properties.
  • Often covered with insulating tape or heat shrink tubing for protection.

5.Scarf Joint:

• Definition: A scarf joint is a splice where the ends of two cables are cut diagonally and joined together.
• Application: Used in low-voltage applications to provide a seamless connection.
• Features:
  • Offers a larger surface area for the connection.
  • Minimizes resistance and energy loss.

6.Western Union Joint:

• Definition: This is a type of joint where the cables are tightly twisted together to form a strong mechanical bond.
