Power transmission and distribution system: Widely used in medium voltage power transmission and distribution lines of urban power grids, rural power grids, and industrial enterprises. It is used for transmitting and distributing electrical energy and can meet the power transmission needs of different voltage levels (such as 6/6kV - 26/35kV).
Industrial field: In industrial places such as factories, mines, metallurgy, and chemical industry, it is used to provide power supply for various medium voltage equipment and production lines, and can withstand mechanical stress and chemical corrosion in industrial environments.
Construction engineering: Suitable for medium voltage power supply systems inside buildings, such as the laying of medium voltage power trunk lines in high-rise buildings, commercial complexes, and residential quarters. It can also be used for medium voltage power transmission of fire protection systems and lighting systems.
Underground engineering: In medium voltage power facilities in underground spaces such as subways, tunnels, and underground parking lots, the armored structure of YJV22 cables can protect the safe operation of cables in complex underground environments.
