- LW<\/strong>: Outdoor SF6 circuit breaker<\/li>\n
- 36<\/strong>: Design serial number<\/li>\n
- 126<\/strong>: Rated voltage (126kV)<\/li>\n
- \/3150<\/strong>: Rated current (3150A)<\/li>\n
- -40<\/strong>: Rated short-circuit breaking current (40kA)<\/li>\n<\/ul>\n
<\/p>\n
Structural Features<\/h2>\n
- \n
- 3-phase porcelain column, single-break structure<\/strong>, with a central spring mechanism for 3-phase linkage.<\/li>\n
- Self-energy arc extinguishing<\/strong> (thermal expansion + auxiliary blowing), low energy consumption, short arcing time, and long electrical life.<\/li>\n
- SF6 gas<\/strong> as both insulating and arc-extinguishing medium, non-flammable, explosion-proof, and safe for densely populated areas.<\/li>\n
- Density relay<\/strong> monitors SF6 pressure in real time to ensure operational reliability.<\/li>\n
- Compact design<\/strong>, small footprint, and long maintenance-free intervals.<\/li>\n<\/ul>\n
<\/p>\n
Application Scope<\/h2>\n
- \n
- Outdoor substations<\/strong> for 110kV transmission and distribution systems.<\/li>\n
- Power grid interconnections<\/strong> as tie breakers.<\/li>\n
- Areas with high altitude<\/strong> (\u22642000m, customizable for 3000m) and heavy pollution<\/strong> (Class IV).<\/li>\n
- Ambient temperature<\/strong>: -30\u00b0C to +40\u00b0C (-40\u00b0C to +40\u00b0C for low-temperature models).<\/li>\n<\/ul>\n
<\/p>\n
Key Advantages<\/h2>\n
- \n
- Alta confiabilidade<\/strong>: Proven self-energy arc extinguishing technology, stable performance under extreme conditions.<\/li>\n
- Low noise<\/strong>: Spring mechanism reduces operating noise, suitable for urban areas.<\/li>\n
- Easy maintenance<\/strong>: Simple structure, no oil, minimal maintenance workload.<\/li>\n
- Import substitution<\/strong>: Fully replaces foreign-made 110kV SF6 breakers with lower cost.<\/li>\n<\/ul>\n
