YBM transformer box



Overview: YBM intelligent box transformer absorbs the advantages of American box transformer, European box transformer and domestic box transformer. It is suitable for my country's national conditions and adopts new environmental protection materials, new technology and advanced components and high and low voltage automation technology. : Among them, the high voltage (12kV) can meet the requirements of the power sector for the automation of the distribution network, and the low voltage (0.4kV) can meet the requirements of the intelligentization of residential property management. This series of intelligent box-type substations is a complete set of intelligent power supply and distribution devices composed of high-voltage units, power transformers, low-voltage units, metering units and intelligent systems. It can be used as urban buildings, residential quarters, municipal facilities, factories, Transformer and distribution equipment for mines, highways, docks, oil fields and temporary power consumption in construction and other departments and places. The box transformer completes the transformation, distribution,

Product details

Main feature:

Ø   YBM is low in price, beautiful in appearance, compact in structure, strong in complete sets, small in size, small in footprint, and can penetrate into the load center;

Ø  Improve the quality of power supply, reduce losses, flexible site selection, strong adaptability to the environment, easy installation, safe and reliable operation, less investment, and quick results;

Ø  The box shell is made of galvanized sheet + anti-corrosion wood strip or stainless steel, which has strong mechanical bending resistance, impact resistance, anti-explosion resistance, radiation resistance and heat insulation ability, and has excellent anti-freezing, anti-cracking and anti-corrosion capabilities. It also has the characteristics of moisture-proof, flame-retardant and non-condensing, and its service life can reach more than 30 years; the box body and top cover are made of heat-insulating materials and have rain-proof eaves.

Ø  All the accessories configured meet the relevant national standards, the combined box-type transformer has a reasonable structure, and has a "five-proof" interlocking mechanism.

Ø  The internal equipment layout and wiring are clear and neat, and the operation, monitoring and maintenance are safe and convenient.
