Technical Data import distribution cabinet, although high, but in most cases only the use of a part, or even simply can not use. Such as the number of imported loop distribution cabinet can be installed in a cabinet than the domestic distribution cabinets are more, but that is the premise of reducing the capacity of the circuit can be achieved, in most cases can not meet user needs. 4. Technical parameters of domestic distribution cabinet although the ratio of imports of low-220v proof distribution cabinet power distribution box, but in most of the domestic power supply system has been able to meet user needs. 5. On the quality of the distribution cabinet, as long as the manufacturers in strict accordance with the requirements of 3C Manufacturing and testing, quality domestic distribution cabinet is not necessarily worse than the quality of imported distribution cabinet. 220v power distribution box explosion proof _ _20 years Koretoyo Yingkou proof distribution box from Zhejiang Koretoyo provide proof electrical Ltd.
