The Physics of Failure: Paschen’s Law at Elevation At high altitudes, such as Sana’a, Yemen (2,250m), the atmospheric pressure is roughly 75% of sea level. According to Paschen’s Law, this reduction in pressure increases the mean free path of electrons, significantly lowering the breakdown voltage of air.
Compliance Risk: The Altitude Correction Factor (Ka) Failure to apply the Ka factor per IEC 60071-2 isn't just a design flaw—it's a liability. At 2,250m, the required clearance distances must be increased by approximately 20%. For compact switchgears, this often results in:
30% Increase in Enclosure Volume: Leading to higher civil and shipping costs.
Thermal Runaway Risks: Thinner air reduces convection cooling, stressing traditional insulation.
Comparative Analysis: Air vs. Woqin Aerogel Composite
| Parameter | Air (at 2250m) | Woqin Aerogel Composite | Engineering Impact |
| Dielectric Strength | Decreased by ~20% | Stable & High | No need for extra clearance |
| Space Requirement | Must increase by 20% | Reduced by 50% | Enables compact design |
| Partial Discharge | High risk due to ionization | Minimized | Extends equipment lifespan |
The Solution: Aerogel as a "Solid Air" BarrierTo solve the conflict between space constraints and high-altitude safety, Hebei Woqin has engineered aerogel-enhanced barriers. By replacing traditional air gaps with aerogel-solid dielectrics, designers can achieve:
Compact BIL Compliance: Meet Basic Insulation Levels without expanding cabinet size.
CUI & Corrosion Protection: Our aerogel coatings also prevent Moisture-Induced Corrosion (CUI), a common secondary failure in high-altitude humidity shifts.
ConclusionHigh-altitude design is about material evolution. Backed by 12 International Lab Reports, Hebei Woqin provides the empirical data needed to guarantee safety when the air gets thin.
