What can change the dielectric strength of conductors during splicing?

The dielectric strength of conductors refers to their ability to withstand electric potential without experiencing electrical breakdown—a crucial factor in ensuring safe and effective electrical splicing. When conductors are spliced, if the insulation is not stripped correctly, it can lead to improper contact between the conductive surfaces or expose more of the conductor to potential voltage, thus compromising the dielectric properties.

Faulty stripping can result in excessive exposure of conductive materials, which might enable arcing, short-circuiting, or other failures, ultimately reducing the overall dielectric strength of the spliced area. This is why it is vital to ensure that the insulation is stripped properly, matching the necessary length for a secure connection but not too much so as to compromise the qualities of the dielectric strength. The process must be done with precision to maintain the safe operating conditions of the conductor.

In contrast, while proper insulation, correct gauge selection, and managing excess conductor length are all essential factors involved in splicing conductors, they do not directly change the dielectric strength at the spliced location as significantly as faulty stripping can. Each of those factors contributes to a safe and effective electrical installation, but the dielectric strength is profoundly affected by the condition of the insulation at the joints, making proper stripping critical.
