Prefabricated Substation

Product Description

YB series prefabricated substations are products produced in compliance with the standards of GB/T17467 "High Voltage/Low Voltage Prefabricated Substations". This product is composed of four parts: housing, transformer, and high-voltage/low-voltage switchgear, and can penetrate deep into the load center. It has the characteristics of small size, beautiful appearance, safety and reliability, and easy installation. It is suitable for outdoor places such as residential areas, factories and mining enterprises, hotels, hospitals, parks, stations, oil fields, airports and temporary facilities.

Product FeaturesProduct Features

It has a unique design, compact structure, and is easy to transport and install. For different use environments, it adopts different heat-proof, moisture-proof, and anti-corrosion measures, and can be sprayed with different colors of paint. It has strong anti-corrosion capabilities and is in harmony with the surrounding environment. coordinated.

It has a good ventilation and heat dissipation system, which is composed of several natural ventilation channels and fans, and has a novel heat insulation layer to ensure that the product operates under conditions of excessive load and temperature.

It has complete monitoring, alarm and protection means, which not only facilitates the maintenance work of patrol personnel, but also ensures the personal safety of personnel.
