**Brand: ROCKWILL** >132kV transmission substations, solar/wind farm booster stations, urban power grid, industrial heavy power projects, where voltage measurement can be arranged externally.
With the development of the power industry, the miniaturization of power equipment is the trend of future development and also the urgent need of current power users. Miniaturized electrical equipment can not only save and and civil engineering costs, etc., but also reduce the use of greenhouse gas SF6, meeting the requirements of the environmental protection situation. Combining years of high-voltage electrical design experience and absorbing the world's most advanced technical design concepts, our company has developed the latest generation of gasinsulated metal composite combined electrical appliance (HGIS). This combined electrical appliance has a compact structure and is particularly suitable for urban and mountainous substations. It is also the best choice for the renovation of old substations. In addition, this product is also very suitable for 40.5kV digital substations and can be used as digital electrical equipment.
RHP-145 is ROCKWILL segregated-tank hybrid gas insulated switchgear (HGIS) rated at 145kV, complying with IEC 62271-203, IEC 62271-100, IEC 62271-102 and KEMA type tested. It adopts self-blast SF6 circuit breaker with bistable spring or spring-hydraulic operating mechanism. Available rated current:2000A,2500A,3150A; rated short-circuit breaking current:31.5kA,40kA,50kA. CB, DS, ES and CT are enclosed in separated SF6 metal tanks while main busbar uses air insulation. This standard version has no built-in PT, voltage transformer can be configured as optional RHP-145+PT variant. It features independent gas compartments, compact layout and factory pre-testing, widely used in 132kV transmission substations, renewable energy booster stations and urban power grid projects.
Hybrid gas insulated switchgear for 40.5kV to 245kV, combining compact GIS design with conventional component flexibility for reliable HV protection.
Hybrid gas-insulated switchgear (HGIS) for 126kV and 145kV, offering compact, reliable, and flexible high-voltage protection solutions.
Hybrid gas insulated switchgear (HGIS) for 145kV and 170kV systems, delivering compact, reliable protection with flexible configuration.
La tension couvre 40,5 kV-145 kV et est adaptée à des scénarios tels que les centrales électriques, les postes de transformation, les chemins de fer, les ports, etc. Elle est particulièrement adaptée aux projets limités en espace tels que les postes de transformation urbains/montagnards, la rénovation des anciennes stations et les postes de transformation sur toit/mobiles.
Le RHP HGIS intègre le disjoncteur, le sectionneur-terreur à trois positions et les TC/TT dans des cuves sous gaz, tout en conservant les jeux de barres AIS conventionnels de type ouvert pour le raccordement sur site. Par rapport au GIS complet, il ne consomme que 20 % de gaz SF₆, réduisant ainsi l'investissement en équipement. Par rapport à l'AIS conventionnel, il réduit considérablement l'empreinte au sol, les points de raccordement et la charge de maintenance. Il offre un équilibre entre compacité, coût et flexibilité d'installation.
Oui. Rockwill propose des services OEM et ODM pour les HGIS de type RHP. Nous sélectionnons des partenaires régionaux qualifiés disposant de solides compétences en ingénierie haute tension et de capacités de service après-vente locales. Nous privilégions une coopération axée sur la technique plutôt qu'une simple activité de revente.
