YB27预装式变电站是黄华集团推出的国产化美式箱变。 该产品作为电缆化配电网中重要的供电单元，集高压控制、保护、变电，以及配电设备于一体的成套预装产品，广泛应用于城乡配电网之中。
该产品将高压负荷开关、高压熔断器置于变压器油中，具有与变压器器身共箱或分箱两种结构形式。 油箱采用全密封结构，配有油温表、油位表、压力表。压力释放阀、放油阀等元件以监测变压器运行状况。 该产品分为环网型、 终端型及双电源型供电方式。 为了使此种产品更适合于我国电网的实际要求，黄华集团又推出了插拔型干式熔断器，熔丝的熔断不影响变压器油的性能。根据低压馈出要求的复杂程度，黄华集团YB27型产品分为标准型、 加强型和综合型三种外壳形式，使用户和设计单位在选型时，做到更灵活、更经济。
YB27 pre-installed substation is a domestic American box transformer launched by huanghua group.As an important power supply unit in the cabled distribution network, this product is a complete set of pre-installed products integrating high-voltage control, protection, transformation and distribution equipment, which is widely used in urban and rural distribution networks.
The high voltage load switch and high voltage fuse are placed in the transformer oil.The oil tank is fully sealed with oil temperature gauge, oil level gauge and pressure gauge.Pressure release valve, oil release valve and other components to monitor the operation of the transformer.The product is divided into ring network type, terminal type and dual power supply mode.In order to make this product more suitable for the actual requirements of China's power grid, huanghua group has also launched a plug and pull type dry fuse, fuse breaking does not affect the performance of transformer oil.According to the complexity of low-voltage feedout requirements, YB27 products of huanghua group are divided into three shell forms: standard type, enhanced type and integrated type.
