⚡ Is your tropical power grid being “double-troubled” by lightning strikes and high humidity?
In Malaysia’s tropical climate, 80% of distribution network outages are not caused by hard faults on lines, but by the “combined impact” of lightning-induced transient faults and insulation aging due to high humidity:
- Frequent thunderstorms: Traditional equipment has simple reclosing logic, leading to repeated power outages after lightning strikes and sharply declining power supply reliability.
- High humidity & condensation penetration: Equipment seal failure, insulation dampness and aging, frequent hidden faults, and doubled O&M costs.
- Consequences: Fines for failing SAIDI targets + high manual inspection costs + surging user complaints, putting power grid operations in a passive position!
Pain Point Truth
Ordinary vacuum circuit breakers lack exclusive lightning protection algorithms and insufficient high-humidity sealing protection, unable to withstand the extreme challenges of tropical power grids.
- Customized for Malaysia’s Tropical Power Grid:Lightning Self-Healing + IP68 Fully Sealed Vacuum Circuit Breaker
- Core Solutions:Precise lightning fault identification+IP68 fully sealed moisture protection+Direct connection to Malaysia power grid protocols

Traditional Solution
Malaysia Exclusive Customized Solution
❌ Weak lightning protection: Mis-tripping / non-tripping caused by lightning, large blackout areas
✅ Intelligent lightning protection: 1-time accurate reclosing for transient lightning faults, self-healing rate ≥95%
❌ Poor sealing: IP65 protection, easy insulation failure under high humidity & condensation
✅ Fully sealed moisture-proof: IP68 protection, zero condensation in 95% high-humidity environment
❌ Complex integration: Protocol debugging required, difficult local O&M
✅ Plug & play: Preloaded with Malaysia power grid standard protocols, no extra debugging needed
Core Values Directly Addressing Malaysia’s Grid Needs
- No fear of lightning:Exclusive lightning identification algorithm distinguishes transient/permanent faults, achieving second-level self-healing after strikes. Power supply reliability improved by 80%.
- Stable operation in high humidity:IP68 fully sealed structure + silicone rubber anti-condensation coating.Outdoor service life extended to 15 years, O&M costs reduced by 60%.
- Perfect local adaptation:Compliant with TNB/SESB power grid standards, English operation interface, direct supply available for local importers, integration cost sharply reduced.
Successful Case
A distribution network renovation project in Malaysia, with over 180 thunderstorm days annually.In high-humidity environment, traditional circuit breakers recorded more than 20 faults per month due to lightning/condensation, with SAIDI consistently unqualified.After adopting this solution:
- Lightning fault self-healing rate reached 98%
- Zero condensation faults during outdoor operation
- Monthly outage duration reduced from 12 hours to 1.5 hours
- SAIDI met standards and won the Malaysia Power Grid Renovation Excellent Project award
- Local O&M team inspection costs reduced by 70%
