Outdoor Type Box Type Substation for Distribution Systems and for Expressway
Product Description
Compact Transformer Substations (CTS) are an important part of the power distribution system, providing a compact and efficient solution for distributing power in various settings, including urban and rural areas. They are designed for use in 12kv, 50Hz three-phase AC systems with a capacity configuration below 2500kVA.
One of the main advantages of CTS is their small size and compact structure, which enables them to be installed in areas where space is limited. They are also highly mobile and can be easily moved to different locations as needed. This makes them ideal for use in temporary power supply applications, such as construction sites or events.
Another advantage of CTS is their safe and reliable operation. They are designed to meet the highest safety standards and are equipped with various protective devices to prevent damage to the equipment and ensure uninterrupted power supply. They are also easy to maintain and require minimal upkeep, reducing downtime and repair costs.
In terms of their use in power distribution systems, CTS can be used in ring network power distribution systems, as well as dual power supply or radiation terminal power distribution systems. They are a cost-effective alternative to conventional civil substations, occupying only a fraction of the space and reducing design workload and construction volume.
Under normal use conditions, CTS can operate within a wide range of temperatures, from -25°C to 40°C, and can withstand winds of up to 35m/s. They are also designed to operate at altitudes below 1000 meters and with a vertical inclination not exceeding 5°.

Production Facilities
Material
1.The cabinet door adopts a double beveled edge process, which increases the structural strength of the same material by 50%.
2.The installation holes are all made using a multi-layer stamping and stretching process, which reduces the sliding wire situation by more than 80%.
3.The inlet and outlet holes adopt a composite structure of knockdown holes and square holes, which can be flexibly selected during on-site installation.
4.The box adopts a double folding process, which increases the structural strength of the same material by 50%.
5.The control circuit adopts a composite design of debugging mode and fire protection mode, greatly reducing the burning of fan and water pump equipment designed for fire protection during debugging.
