Prolongation Splice (Empalme de Prolongación)
The prolongation splice is a fundamental technique used to extend the length of an electrical cable or repair a cut wire. This method involves twisting the strands of two conductors together to ensure a secure and reliable connection. It is commonly employed in open installations and for conductors up to 4 mm². The simplicity of this splice makes it ideal for scenarios where cables are not subjected to movement or tension. Proper insulation is crucial to prevent electrical hazards, and the connection must be tightly secured to avoid any loose ends. This splice is widely used in applications such as telephone lines and overhead electrical wiring, where durability and safety are paramount. By following precise steps, the prolongation splice ensures minimal resistance and maximum conductivity, making it a essential skill for electricians and technicians.
Rat-Tail Splice (Empalme Cola de Rata)
The Rat-Tail Splice, also known as the twisted splice, is a simple and effective method for joining two electrical conductors. This technique is commonly used when the cables are not exposed to significant movement or tension, making it ideal for junction boxes, circuit assemblies, and other stationary applications. The process involves twisting the stripped ends of the wires together to create a secure connection. This splice is particularly useful in scenarios where space is limited, as it requires minimal room to execute. It is also a popular choice for DIY projects due to its straightforward nature. However, it is important to ensure that the connection is tightly twisted and properly insulated to prevent electrical hazards.
