China Ring Main Unit Manufacturer, Supplier, Factory

TOONICE focuses on the integration field of photovoltaic equipment. Our photovoltaic prefabricated cabin, with modular design and intelligent temperature control technology as its core, serves more than 500 photovoltaic power station projects such as State Power Investment Corporation and Three Gorges New Energy. The prefabricated cabin is equipped with advanced artificial intelligence temperature control system to ensure equipment stability. And, we support customized extensions, fast installation, and easy mobility.

Toonice's vacuum circuit breakers feature a small size, light weight, suitability for frequent operations, and no need for arc extinction maintenance, making them widely used in distribution networks. As indoor power distribution equipment for 3～10kV, 50Hz three-phase AC systems, vacuum circuit breakers are used in industrial and mining enterprises, power plants, and substations to protect and control electrical equipment. They are especially suitable for applications requiring oil-free operation, minimal maintenance, and frequent switching. These circuit breakers can be installed in medium-mounted cabinets, double-layer cabinets, and fixed cabinets to control and protect high-voltage electrical equipment.

Toonice's American Type Prefabrication Substation feature core advantages such as high efficiency, reliable operation, convenient installation, and compact durability. Our products ensure quality through premium materials and strict craftsmanship, offer competitive pricing, and provide professional ODM/OEM services for personalized customization, meeting diverse project needs as a cost-effective choice in the power distribution field.
