Wire splicing. Doing step by step!

For an electrician to make the wire splicing is something common, but perhaps because he does not have the necessary knowledge of how to splice wires and what types of splices, they end up failing in the execution of this service, because their splices fail to offer safety and efficiency. Learn how to make a splice correctly, what types of splices and types of electrical connectors exist, come on guys!

The poorly made splice can bring major problems to the circuit, is one of the main causes of defects within an installation, so the splice should be carried out in the best possible way.

One of the factors that influence the efficiency of an electrical installation is the amendments, if it is poorly insulated or done incorrectly, it can cause significant losses due to the dissipated heat.

It is important to understand that there are two types of cables, rigid and flexible. The rigid cable consists of only a copper wire (in some cases aluminum). The flexible cable, on the other hand, is formed by several copper wires, also in some cases, it can be aluminum, in compensation these wires are much thinner.

There are several types of cables and for that, each one has specific methods to make the amendments. The splice will never replace a cast cable, that is, without seams, as its mechanical characteristics will never be the same, but if the splice is well-executed, these differences can be minimized to the maximum.

Tips to make an amendment with safety and quality:

Some care must be taken when making a bypass splice, one of them is when stripping the wires, never use a stylus, as it is an instrument that was not manufactured for this type of heavier work. The stylus is a flexible instrument made of fragile materials, use a pocket knife if you do not have the appropriate tool.

To give a better fixation of the conductors, finishing and not getting points capable of damaging the insulation of the seams, use universal pliers.

When insulating the seam, pass the electrical tape several times until it is the same thickness as the wire itself. The deterioration or overheating of this amendment can occur if the insulation is made with a small amount of electrical tape.

Whenever it is possible to pass tin through the cables, as solder is made in a wire of electronic devices, as this is a process in which the tin penetrates the copper ensuring that this splice is as close as possible to a molten cable and in this way will reduce heating in this amendment.

Making amendments step by step:

Bypass splice:

The splice is used to derive several conductors from another single conductor without cutting it, just stripping a part in the center where you want to make this derivation, from there the splice of the conductors will be made.

Rigid wire:

Uncover a part of the conductor with the help of stripping pliers or a pocket knife to make the conductor derivation, always keeping the two cables together and wrapping each other. So that they are firm, finish the seam with the aid of universal pliers.

Flexible wire:

Also with the help of stripping pliers or a pocket knife in the center of the conductor. Place the conductor in the center so that it forms a “hole”, insert the second bypass conductor in the center of the bypass conductor.

Rotate the conductor that was introduced in the tap to each side inside the main conductor. To obtain a very strong seam, use the universal pliers to fix the seam.

Connection splice:

The connection splice, also known as pig’s tail, is widely used to join two or more conductors in passage boxes. This type of splice is used in rigid conductors.

Rigid wire:

Leave the two wires bare, both at a 90 ° angle and use universal pliers to hold the wires together. Use your other hand to rotate the living part, maintaining the 90 ° angle until you get a braid.

At the end of the splicing, use other universal pliers to keep turning, so as not to hurt yourself and keep the seam tight. To finish the finish, just bend the sharp points that are left from the seam, to avoid piercing the insulation. After that, just do the welding and perform the insulation.

Extension splice:

This type of splice, as the name implies, is used to increase the length of the conductors, having excellent mechanical resistance.

Rigid wire:

Remove the insulation towards the ends and cross the ends of the conductors, forming an angle of 90 °, then immediately twist one conductor over the other in the opposite direction. Complete the twisting of the tips with the aid of one or two pliers so that the tips are completely wrapped and tightened on the conductor.

Flexible wire:

Remove the insulation from the conductors, both of the same size, then separate the two cables, with the filaments well separated.
