What is medium voltage cable? Many people know about low-voltage cables and high-voltage cables, but very few people know about medium voltage cables. The voltage range of medium voltage cables
This question first involves a concept, that is, the relationship and difference between kVA and kW. kVA (kilovolt-ampere) is the unit of apparent power, and kW (kilowatt) is the unit
What is the qualified value of transformer high and low voltage insulation resistance? The qualified standard for insulation resistance of power transformers in operation is: for 10KV level and below,
Why must the neutral point of the transformer be grounded when it is shut down? Answer: This is mainly a measure taken to prevent overvoltage damage to the transformer. For
Power transformers are classified in many ways according to different classification methods, but our common transformers are often oil-immersed transformers, dry-type transformers and box-type substations. Today we will talk about
1. Compact structure, small size, easy installation and flexibility; 2. Fully insulated, fully sealed structure, safe, reliable, maintenance-free, and reliably protects personal safety; 3. The high-voltage side is protected by
1. Power: When using a single-phase transformer, you need to select the appropriate power according to actual needs. At the same time, attention should be paid to the carrying capacity
Transformer impedance refers to the electrical resistance inside the transformer, which is mainly composed of factors such as wire resistance, insulation material resistance, and iron loss in the magnetic circuit.
