Prefabricated compact substation, also known as prefabricated substation. It is a prefabricated indoor and outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformer and low-voltage power distribution device according to certain wiring scheme. The transformer step-down, low-voltage distribution and other functions are organically combined together, installed in a fully enclosed and mobile steel structure box which is moisture-proof, rustproof, dustproof, rodent proof, fire prevention, anti-theft, and heat insulation. Box type substation is suitable for mines, factories, oil and gas fields and wind power stations. It replaces the original civil construction distribution rooms and power stations and becomes a new complete set of transformer and distribution devices.

1600kvar Medium Voltage Reactive Compensation Electric Distribution Cabinet(hereinafter referred to as the device) is suitable for 10kV AC power system with frequency of 50Hz. It is mainly used in power system to adjust bus voltage and reactive power, improve power factor, improve voltage quality and reduce network loss.
