In the core "Three Electric" systems (battery, motor, electronic control) of new energy vehicles, the busbars connecting capacitor units play a vital role. Their performance directly impacts the vehicle's operational efficiency, reliability, and safety. Facing harsh environments such as high temperatures, high humidity, vibration, and electrolyte leakage, the insulating protection on busbar surfaces has transcended mere aesthetic needs, becoming a critical line of defense for ensuring the long-term stable operation of capacitor units.

JIADUOCAI RAL2008 Red

JIADUOCAI's "RAL2008 Red" high-performance powder coating is specifically engineered for insulating busbars in new energy vehicle power distribution systems. With its triple-insulation-barrier core technology, it creates a safeguarded zone for automotive capacitor systems.

Excellent Insulation Performance

With electrical strength ≥30 KV/mm, it provides a robust insulating barrier to prevent high-voltage breakdown and ensure system safety.

Featuring insulation resistance ≥500MΩ (DC1000V/60s), it maintains excellent insulating properties even in high-voltage environments, effectively eliminating risks of electrical leakage.

With low leakage current ≤1 mA (DC3800V), it achieves near-zero energy loss, enhancing energy efficiency and eliminating safety hazards.

With volume resistance up to 10¹⁵Ω·cm, it provides a solid insulating foundation for high-voltage busbars.

Long-Lasting Anti-Corrosion Performance

Acid and Alkali Test: Immersed in 10% sulfuric acid and 10% sodium hydroxide solutions for 24 hours, the coating shows no blistering or wrinkling. It remains unaffected by electrolyte leakage, maintaining consistent insulation performance.

1000-hour Salt Spray Test: Under 85℃ high temperature and 85% RH high humidity conditions, the insulation layer shows no blistering or cracking, demonstrating proven resistance to coastal and de-icing salt corrosion.

Cross-Cut Test: Adhesion maintained at ≤1 level. The insulation layer remains firmly bonded even under extreme corrosion, significantly extending the safe service life.
