A two-part thermal silicone encapsulant replaces air gaps between high-voltage components with solid insulation: 10 kV/mm dielectric strength, 1 × 10^13 Ω·cm volume resistivity, UL 94 V-0, plus the dielectric strength formula and an inquiry checklist.

Thermal conductive silicone cloth rated above 4kV withstand voltage, 0.8–3.0 W/m·K and 0.2–1.0 mm thick: how thickness balances insulation margin and heat flow in power supplies and PCBs.
Before selecting H-TT-AL, verify working voltage, test conditions and the actual insulation path instead of treating aluminum heat spreading as assembly insulation.
A conductive silicone cap is not just a cover. It has to balance voltage stress, insulation thickness, mounting clearance, and heat dissipation.
