Jointing and termination are critical interfaces and potential points of failure.

• Skilled Technicians: These tasks must be performed by highly skilled and certified jointing technicians with specific experience in 66 kV cable systems.

• Quality Accessories: Only use high-quality, pre-tested, and type-approved cable accessories, such as heat-shrinkable or cold-shrinkable joints and terminations.

• Controlled Environment: The work must be carried out in a clean, dust-free, and moisture-controlled environment to prevent contamination that could lead to electrical failures.
