For a high-voltage shielded cable splice, which connector type is recommended?

• A. Crimp
• B. Solder
• C. Compression
• D. Mechanical lug

Answer: (C)

Preserving shielding while delivering a dependable, low-resistance electrical joint is crucial in a high-voltage shielded cable splice. A compression connector is designed to apply a uniform compressive force around the conductor and the shield braid, creating a solid metal-to-metal contact and preserving shield continuity. This yields a low-resistance, environmentally sealed joint that remains reliable under vibration, bending, and thermal cycling—conditions common in HV installations. Soldering introduces heat that can damage insulation and insulation aging, and may not maintain shield integrity or long-term durability. Mechanical lugs can fail to maintain a continuous shield and seal, while a properly applied compression splice is specifically built for maintaining shielding, impedance, and environmental protection in high-voltage cables.
