Oil Arc Extinguishing Chamber for Outdoor Load Switches

1. Material and Construction

• Molded from special epoxy resin:
  • Highly resistant to ultraviolet (UV) radiation, ensuring long-term outdoor durability.
  • Can withstand high temperatures without degrading.
  • Seals the oil inside, preventing leaks and ingress of moisture or contaminants.

2. Application

• Designed specifically for outdoor load disconnect switches (also called load break switches).
• The oil-filled chamber safely extinguishes the arc formed during switching operations under load.

3. Performance

• Operating temperature: Up to 300 °C, accommodating heat from the arc and ambient conditions.
• Environment: Suitable for outdoor installations, exposed to sun, rain, and varying weather conditions.

4. Advantages

• High durability in harsh outdoor environments.
• Maintains arc-quenching efficiency over time due to epoxy molding and oil insulation.
• Minimizes maintenance requirements, as oil is protected from contamination.
• Reduces risk of oil leakage, enhancing operational safety.
