Prefabricated Compact Substation

Product Structure Characteristics

●The skeleton structure of the box shell is made of channel steel and angle steel with high mechanical strength, and the outer shell is made of aluminum alloy plate with smooth and flat surface.
●The outer shell is made of aluminum alloy plate and other materials with smooth and flat surface, the products are beautiful and generous, and have better anti-corrosion performance. The base of the box is 300-600mm above the foundation.
●The low voltage of the transformer can be designed as 0.69KV according to the requirements of customers. All doors of the cabinet shell are open to the outside, the opening angle is more than 90°, and the positioning device is provided. The cabinet is also equipped with handles, secret latches and secret locks that can prevent rain, blockage and rust.
●The cabinet is equipped with handles, secret latches and secret locks which can prevent rain, blockage and rust. The box are all sealed anti-theft structure; in order to ensure that in the general operating temperature of the surrounding air, the temperature of all electrical equipment does not exceed its maximum permissible temperature.
●To ensure that the temperature of all electrical equipment does not exceed the maximum permissible temperature during operation under normal ambient air temperature, the enclosures are provided with sufficient natural ventilation openings and insulation measures.
●The box of the pre-installed substation is equipped with a special grounding conductor, and the grounding conductor is equipped with a fixed connection terminal connected to the grounding network, the number of which is more than two, with obvious and clear connection terminals.
●There are two or more terminals on the grounding conductor which are connected to the grounding network and have obvious grounding marks. The grounding terminals are copper bolts with a diameter of not less than 12 mm. The grounding conductor is made of copper
●The grounding conductor is made of copper tape with a current density of not more than 200A/mm and a cross-section of not less than 30mm, and is guaranteed not to overheat or affect the safety of surrounding objects when flowing through the maximum short-circuit current.
●It is guaranteed that the maximum short-circuit current will flow without overheating or affecting the safety of surrounding objects. The dynamic and thermal stabilized currents of the dedicated grounding conductor should be compatible with the grounding method of the HV distribution
