What is normally used to terminate cables with solid dielectric insulation?

• A. A voltage stress-limiting manifold
• B. Molded rubber terminators
• C. Bolt on clamp
• D. Oil filled porcelain potheads

Answer: (B)

For cables with solid dielectric insulation, the termination must smoothly fit the solid insulation, seal out moisture, and provide a reliable electrical finish without relying on oil. Molded rubber terminations are designed specifically for solid-dielectric cables—they’re pre-formed, weatherproof, and grip the conductor and insulation properly while creating a clean, insulated end. This makes them the standard choice for solid insulation. In contrast, oil-filled porcelain potheads are intended for oil-filled cables where the oil provides the dielectric medium, so they aren’t appropriate for solid-dielectric conductors. Bolt-on clamps are only mechanical grips and don’t address the electrical termination needs, and voltage stress-limiting manifolds are specialized devices for managing field distribution in certain terminations rather than generic terminations for solid insulation.
