When working with electronic equipment or with electrical wiring, it may from time to time become necessary to splice or join wires together. Splices and joints are essentially the same thing. Several different methods of doing this exist. The fundamental necessities of an effective splice include making sure the wires are securely fastened to each other even without solder and that they are well-soldered to avoid corrosion. All wire joints must also be taped with electrical tape after soldering.
A splice joint is a method of joining two members end to end in woodworking. The splice joint is used when the material being joined is not available in the length required. It is an alternative to other joints such as the butt joint and the scarf joint. Splice joints are stronger than unenforced butt joints and have the potential to be stronger than a scarf joint.
Splices are therefore most often used when structural elements are required in longer lengths than the available material. The most common form of the splice joint is the half lap splice, which is common in building construction, where it is used to join shorter lengths of timber into longer beams.
WHAT ARE THE IMPORTANCE OF SPLICES ANS JOINTS?
The connections must be well made and the wires tightly joined to prevent a loss of voltage to the device powered. In high current situations a poor connection causes heat at the connection and oxidiation of the wires and no more or intermittent connections.
Most problems in electrical is not a short but: an open connection.
In the case of high-voltage underground cables, the restoration of the insulation is critically important, as is restoring the cable's waterproof integrity. The skills required are such that cable jointers serve a full apprenticeship in that particular trade.
