Introduction
YB series of modular substation, is a combination of high-voltage electrical equipment, transformers, low voltage electrical equipment, such as a compact power distribution unit for urban high-rise buildings, urban and rural construction, residential areas, factories, parks, airports, railways, oil, Shopping malls and temporary construction of electricity and other places for the distribution system to accept and distribute the use of electricity.

Features
YB series of pre-installed box-type substation by the high-voltage switchgear, transformers, low-voltage switchgear and the four parts of the combination of outdoor compact power distribution station for voltage 10 / 0.4KV three-phase AC system as a receiver and Distribution of power distribution products. The product has a compact structure, small size, small footprint, fast installation, easy maintenance and so on.
The product of high-voltage switchgear of the company's own production of XGN series switchgear, SDC series of fully enclosed all-insulated inflatable switchgear; transformer using dry or oil-immersed transformers; low-voltage switchgear GGD series, GCS series, GCK series of low pressure Switchgear.
• The substation is made of surface-treated steel with sufficient mechanical strength and rigidity.
• The cold-rolled steel plate, stainless steel plate, aluminum plate, composite color plate and so on are used for the shell material.
• The steel plate is separated from each room. small room, its internal shape can be arranged "head" type "product" type and other forms;
• In order to facilitate monitoring and maintenance, transformer room, high and low pressure chambers are equipped with a lighting device;
• cover for the double structure, can increase the indoor temperature to prevent heat radiation;
• natural ventilation main transformer, when the transformer room temperature exceeds the set temperature, mounted on the top of the axial fan automatically starts to control the temperature of the transformer chamber;
• rotatable connecting portion Are equipped with a sealing device, so that it has a good moisture resistance;
• improved protection performance, easy operation, high pressure side with a full five anti-function, to ensure the safety of maintenance;
• compact, beautiful appearance, can be coordinated with the surrounding environment The
