組合式變壓器（美式箱變）是將高壓開關、變壓器和低壓配電設備按一定的接線方案組合在箱體內小型化配電設備。作為高壓配電計量，補償控制和保護裝置，高壓側裝有四工位或二工位負荷開關，后備保護熔斷器及插入式熔斷器，低壓側可按用于要求裝設控制電器、配電電器、補償裝置及電能計量表等，本公司生產的組合式變壓器具有損耗低、噪音低、安全可靠、體積小、外形美觀、安裝周期短等優點。
Combined transformer (American box) is the high voltage switch, transformer and low voltage power distribution equipment according to a certain terminal portfolio in the box body, miniaturization of power distribution equipment. As a high voltage distribution measurement, compensation control and protection device, high voltage side is provided with four station or two position load switch, and insert backup fuse according to the requirements, the low-voltage side for the installation of control electrical appliances, electrical distribution, compensation device and electric energy meter. The company's combined transformer with advantages of low loss, low noise, safety and reliability, small size, beautiful appearance, and installation short cycle.
