9-Grade Seismic Resistance：Karakara na kusa da karamin tsari mai yawa wanda ke taimaka da shi a lokacin da zafi mai tsari 9, wanda ke taimaka da shi a wurare da take da tsakane mai tsari -- babban faidandin da ke samu sirrin RHD.
Ultra-Efficient Arc Extinction & Long Lifespan：Karamin kula mai yawa na kula mai yawa wanda ke taimaka da shi a lokacin da kawo karami ≥50kA rated short-circuit breaking current. Daga 10,000 electrical operations da 10,000 mechanical cycles, yana kawo kula da kula da kuma kawo kula da yanayi.
Zero-Pollution Eco-Friendly Design：Ba ta da SF6 ko greenhouse gases -- yana kawo kula da kwalba da kuma karshe da al'amuran zamani, wanda ke taimaka da hukumar da kula mai yawa da kula da kula da kula da kula.
Modular Flexibility for Any Layout：On-demand built-in current transformers (up to 15 for measurement/protection) and standardized module interfaces enable flexible combinations. Ideal for space-constrained substations and diverse design needs.
Extreme Environmental Adaptability：Thrives in harsh conditions: -40℃ to +55℃ ambient temperature, 32K daily temperature difference, 3,000m altitude, Class IV air pollution. Resists 700Pa wind pressure (34m/s) and 20mm icing -- reliable anywhere.
Comprehensive Safety Protection：Anti-mis operation interlocking devices prevent human-error accidents. Pre-delivery lightning impulse tests eliminate insulation discharge risks, ensuring uncompromised quality.
Maintenance-Free Spring Mechanism：Oil-free, gas-free spring-operated structure delivers stable performance, low noise, and high reliability -- cutting long-term operational workload to zero.
