Power cable joints, also known as cable splices or cable terminations, are used to connect two or more sections of electrical power cables together.

Cable Length
Power cables are often manufactured in standard lengths. Cable joints are necessary to connect shorter lengths of cables to reach the desired length for a particular application.

Repairs
In the event of a damaged or faulty section of a power cable, cable joints allow for the removal and replacement of the damaged portion without the need to replace the entire cable run. This can be a cost-effective way to address cable issues.

Installation Flexibility
Cable joints offer flexibility during the installation process. They allow for adjustments and modifications to the cable route without having to procure new cables of different lengths.

Voltage Change
When changing the voltage level of a power distribution system, cable joints can be used to connect cables of different voltage ratings, ensuring a smooth transition and maintaining electrical continuity.

Environmental Protection
Cable joints provide environmental protection to the cable ends. They help seal the cable against moisture, dust, and other contaminants, which can degrade the cable's insulation and conductor over time.
