ODES Sand-Resistant Relays for Harsh Environments

Field Challenge: Sandstorms in Northwest China

In northwestern regions, strong winds and sandstorms are a constant threat to power equipment:

• Relays and selector switches in control cabinets suffer from dust accumulation, mechanical jamming, and coil degradation.

• Operators report trip failures, protection malfunctions, and unreliable manual switching.

• Maintenance risks escalate, directly threatening system safety.

ODES Technical Response

Instead of accepting environmental limits, ODES engineered a dedicated solution combining protection relay expertise with environmental hardening:

1. Integrated protection technology: High-voltage relay design combined with compact electronic integration ensures stable operation.

2. Fully sealed relays: Dust cannot penetrate, guaranteeing long-term reliability.

3. PCB and component protection: Triple defense against mold, moisture, and sand extends component life.

4. Reinforced enclosures: High-strength housings designed specifically for harsh conditions.

5. Fully sealed selector switches: Shielded contacts ensure dependable manual operation under all conditions.

ODES Sand Resistant Relay Series

Customer Value Delivered

With these design measures, ODES provides relays and control solutions truly adapted to desert environments:

• No more dust-induced failures.

• Secure protection performance without nuisance operations or missed trips.

• Improved maintenance reliability and reduced operational risk.

In the harshest environments, stability is the ultimate requirement. With a focus on customer challenges, ODES continues to combine relay protection technology with innovative environmental protection to safeguard reliable power-system operation.
