1. ​Ụbụchị SF6 Kpata: Na ohere mmiri 0.6 MPa, agụ SF6 kpata n'ọkachasị -25°C. Oyi ezi ekweghị mfe maka kpata, nke na-akwalite ụdị nri anya na-eme ọrịa.
2. ​Ahụike Ahụike: Ụlọ ahụ nwere ike ịdị n'oge ahụike dị ka 8 degrees. Ụdị akwụkwọ nwere ịkpọ mkpa nwere ike ịgbanwe mgbe ahụike ma ọ bụ ịkpọ mkpa mmiri.
3. ​Ịkpọ Mkpà Ụka n'ụzọ Ụka: Ụka nke ụzo nwere ike ọ bụla, nwere ike ịkpọ mkpa ụka n'ụzọ ụka n'ime ụka, nke na-akwalite ụka dị elu na ọgbaghara ụka.

​II. Ụdị na Ịnye SF6 Circuit Breaker Na-ekwu Nke A​

1. ​Ụdị Anti-Kpata​
   • ​Ụka Onye Nsọ: Nke a na-enyere ụka onye nsọ nke nwere ọṅụọṅụ 800–1,200 W n'okpuru akwụkwọ nri anya. Ọ na-egosi ọnụọgụ ọkachasị nke nwere ike ịkpọta SF6 gas n'ọkachasị -18°C (nwere ọkachasị -25°C n'ọhere mmiri 0.6 MPa).
   • ​Ụdị Nsọ Nri Anya: Ụdị nri anya nanogel aerogel nwere ike ịkọnyere akwụkwọ nri anya na pipeline, nke na-akwalite ọkachasị nri anya ịkọnyere 30% n'oyi ezi.
2. ​Ụdị Ịkpọta Ahụike​
   • ​Ụdị Pipeline Nwere Ọṅụọṅụ: Pipeline SF6 nwere ọṅụọṅụ nwere ike ịkọnyere ọṅụọṅụ ±15 mm na ọṅụọṅụ ±10 mm, nke na-akwalite ịkpọta ọṅụọṅụ n'ọkachasị ahụike.
   • ​Ụdị Bracket na Ụdị Isolation Bearings: Bracket nwere ụdị Q345B steel na ụdị cross-bracing, nke na-akwalite friction pendulum isolation bearings n'okpuru ụka ịkọnyere 80% nke ụka ahụike, nwere ịkpọta ụka acceleration response n'ọkachasị 0.3g.
3. ​Ụdị Ụka N'ụzọ Ụka​
   • ​Ụka Training Center: Ụka training base n'Addis Ababa nwere ụka courses nke nwere ọṅụọṅụ (English/Amharic) nwere ọṅụọṅụ SF6 gas detection, ụdị onye nsọ, na ụdị ụka post-earthquake.
   • ​Ụdị Monitoring Smart: IoT sensors nwere ike ịkọnyere ọkachasị mmiri, ọkachasị, na ọṅụọṅụ. AI algorithms nwere ike ịmepụta ụbụchị na ịkọnyere ụka, nwere ịkpọta ụka manual inspections n'ọkachasị 50%.

​III. Ụdị Ụka​

1. ​Ụdị Anti-Kpata Dị Mfe: Ụdị onye nsọ nwere ike ịkọnyere ọkachasị nri anya ịkọnyere -18°C, nwere ịkpọta ụbụchị SF6 kpata. Ụka ụka nwere ọkachasị 0.5 incidents per unit.
2. ​Seismic Compliance: Ụdị ọṅụọṅụ na ụdị isolation nwere ike ụka ịkpọta ụka ahụike 8 degrees, nwere ịkọnyere ụka 95% functional integrity post-earthquake.
3. ​Ụdị Ụka Dị Elu: Ụka technician ụzọ ụka ịkọnyere 3 months. Ụka ụka ọgbaghara ụka ịkọnyere 72 hours to 8 hours, nwere ịkpọta lifecycle costs n'ọkachasị 40%.
4. ​Environmental Adaptability Verified: Ụdị a nwere ịkọnyere -40°C low-temperature tests na simulated seismic platform trials, nwere ịkọnyere ụka composite demands nke East Africa's high-altitude, low-temperature, na high-seismic environments.
