Pre-installed Transformer Substation description AC metal closed type shift switch cabinet is a three-phase AC 50HZ indoor device metal-enclosed switchgear, used in power plants and substation systems with a rated voltage of 35kV, a rated maximum current of 2000A, and a single bus or section...
Description
We combined with many years of practical experience and developed a series of high voltage distribution cabinet, Three Phase Oil Immersed Transformer, AC metal enclosed switchgear. It has been rented and rented by customers for a long time and is the first choice for customers to choose similar products. We have state-of-the-art equipment.
YB pre-installed American substation:
This product puts the high-voltage load switch and high-voltage fuse in the transformer oil, and has two structural forms: the same box or the sub-tank with the transformer body; the oil tank adopts a fully sealed structure, and is equipped with an oil temperature gauge, an oil level gauge, a pressure gauge, Pressure relief valve, oil drain valve and other components to monitor the operating status of the transformer; as an important power supply unit in the cabled distribution network, this product is a complete set of pre-installed products integrating high-voltage control, protection, transformation and power distribution equipment. Used in urban and rural distribution networks.
1. Altitude: ≤1000m; ambient temperature; -25℃~+40℃;
2. Temperature: the highest monthly average temperature +30℃, the highest annual average temperature +20℃;
3. Relative humidity: daily average value is not more than 95%, monthly average value is not more than 90%;
4. Anti-vibration level: horizontal acceleration 0 4m/s, vertical acceleration O 15m/s;
