Product Details

Prefabricated Electrical Substation Box 4000A Rated Current For Power Distribution

Overview

Hengfengyou offer an environmentally responsible, high efficiency, safer choice. The units have high-fire-point fluid, providing fire safety benefits, and a projected life well beyond that of a traditional mineral-oil transformer. These efficient and cost-effective transformers use Environmental friendly oil. Envirotran transformers are manufactured in 50 - 10,000kVA, in primary voltage classes of 11kV,15 kV, 25 kV and 35 kV.

capacity kVA 50-20,000

Primary Voltage Up to 34,500 V

Secondary Voltage 208-14,400 V

Application

Three-phase, pad-mounted transformers, for use on underground power distribution systems, are best suited for commercial applications in public access areas and where underground service is required. These transformers meet modern design requirements for flexibility and provide a visually pleasing installation. Construction allows installation in locations accessible to the general public without the need for protective fencing or vaults. These units are ideally suited for apartment buildings, schools, hospitals, shopping centers, commercial buildings, or industrial sites.

Service Centre

_{The shell of the box is made of aluminum-coated zinc steel plate
and container manufacturing}_{technology, and the design is beautiful. On the premise of ensuring
the reliability of power supply,}_{the shell color of the box-type substation is selected, so that it
is easy to be in harmony with the}_{surrounding environment Especially suitable for urban construction.}

_{Such as: Urban residential}_{areas, stations, ports, airports, parks, green belt and other
densely populated areas, it can be}_{used as a fixed substation, can also be used as a mobile
substation, with decorative and}_{beautifying the environment.}
