Splicing an electrical cable is a procedure that must be carried out carefully. This is because ignoring certain precautions creates risks capable of triggering significant losses for the industry.

Safety is a serious matter, here is some information that will help make splicing much safer and more efficiently.

What is an electrical cable splice?

Basically, it is about joining the ends of two conductors. This must be carried out in order to guarantee the mechanical resistance is correct and the electrical contact perfect and without risks. 

Splices have several functions. For example, lengthen conductors power supply or even reconnect them in case of breakage. In addition, they are used to perform derivations in a main network of wires, this is the case of installing a point of light.

What is the importance of a well-made electrical cable splicing?

In an ideal scenario, the fewer splices there are in the installation, the safer it will be. However, the procedure is part of the electrical maintenance routines and will not always be avoided. In view of this, the essential is to take all precautions so that the company does not suffer with accidents or other types of problems, such as short circuits and production interruptions.

For this reason, we say that performing splicing of wires properly is one of the most important steps in electrical installation.

When poorly executed, it totally damages the installation and even causes damage like:

• heating of electrical conductors;
• electricity leakage;
• interruption of the passage of energy;
• voltage drop;
• increased energy consumption;
• damage to industrial equipment and tools.

Weld or no weld splice: which one to use?

After all, which type of splice is more reliable: welded or non-welded? That is a controversy of the daily life of electricians and electrical engineers, so it is important to clarify some issues. Some professionals in the area always solder with tin in the amendments. On the other hand, some prefer to avoid under the argument that this type of procedure is prohibited. But what's true about it all?

It is advisable to avoid the use of soldered connections in electrical circuits. If they are used, it is important that they have resistance to creep and mechanical stress compatible with the

destination. Knowing this, it is clear that the weld seam is not prohibited. However, for reasons of safety and efficiency, it is ideal to avoid it whenever possible.

It is interesting to avoid curvatures in the wires that will be spliced, since this wears out the junction of the cables and interferes with their efficiency and security. The connections must not be inside the conduits, but in the passage boxes, which facilitates future  maintenance.

Splices should always be tight and secure, this is a rule that should not be ignored, since the days off are one of the causes of heating of wires and rupture of joints.

Finally, use care when stripping the flexible cable to prevent it gets damaged. Despite being a simple tip, many installations are harmed due to errors and lack of care at this stage. A well-executed electrical cable splicing avoids numerous problems and damage to your business, home, car, boats etc…

However, by putting all these precautions into practice, and using high quality wire connectors,  you guarantee the safety of its employees, increases the useful life of its equipment and keep everything in full working order
