In the power distribution industry, everyone knows that transformers are usually unremarkable in daily use, but when they malfunction, it can be a major problem. Let me mention a few common situations: After several years of operation, it starts to leak oil, and the outer shell becomes greasy with oil, which is not only unsafe but also unsightly; The noise gets louder and louder, making people's heads ache; The heat dissipation cannot keep up, and it trips the circuit breaker frequently on hot summer days. In essence, these problems are due to the fact that this 10KV Oil Immersed Transformer did not fully consider the actual working conditions in its design. Many manufacturers, in an effort to save costs, use ordinary silicon steel sheets and low-grade insulating oil. For a short period of time, no problems are noticeable, but over time, the flaws will become apparent.

The client is also facing a headache. When purchasing the transformer, the manufacturer promised a 20-year warranty. However, problems started occurring within just three to five years. When seeking after-sales maintenance, the round trip caused delays in the project schedule, resulting in greater losses than simply buying a new one. What's more troublesome is that some projects require specific voltages or installation dimensions, and there are no ready-made options on the market. We can only do with what's available, which brings even greater hidden dangers in the future.

The way Hualai Electric  produces products is quite different. We don't follow the approach of uniformly lowering prices for generic models. Instead, we thoroughly consider each step. For instance, this 10KV Oil Immersed Transformer uses high-magnetic-conductivity cold-rolled silicon steel sheets for the core, and its no-load loss is about 15% lower than the national standard. The coil is wound with all-copper wire, which has much better conductivity than aluminum wire, and the temperature rise is better controlled, so it doesn't overheat during long-term operation. The casing undergoes acid washing and phosphating treatment, then is sprayed with plastic, and its rust prevention ability is much stronger than ordinary spray painting. In coastal areas, it has been used for five or six years without any rust spots.

If you have special requirements, such as incorrect voltage levels or limited installation space, we offer the Customized Oil Immersed Transformer service. Just send us the dimensions, capacity and voltage parameters, and the technical team will directly provide the drawings. We will make minor adjustments using the existing molds without having to create new ones. The cycle is short and the cost is controllable. The quality is the same as the standard products. The warranty period is five years. If there is any quality issue, it will be replaced. There will be no evasion or procrastination.

When it comes to the durability of Oil Immersed Transformers, it is not achieved merely by adding more components; Rather, it is due to the attention to details. For instance, all the weld seams of the oil tank are welded using gas protection welding, not ordinary manual welding. After welding, a positive pressure leak test is conducted to ensure there are no cracks. The sealing rubber strips are made of oil-resistant nitrile rubber, not ordinary rubber pads. Even after long-term use, they will not harden and cause oil leakage. The heat dissipation tubes are elliptical tubes, which have a larger heat dissipation area than round tubes. The tube spacing has also been optimized, making it less likely to accumulate dust. These details are not visible, but you can tell how convenient they are when in use.

Product features:

1.Low-loss design: High-permeability silicon steel sheets combined with all-copper coils. The no-load loss is 15% lower than the national standard, and the annual electricity savings are enough to buy an air conditioner.

2.Oil-proof structure: Gas protection welding combined with positive pressure leak testing. The rubber strips are made of nitrile rubber, and there will be no oil stains even after using for ten or twenty years.

3.Customization support: Voltage, size, and capacity can all be adjusted according to your needs. There's no need to compromise on standard models. Just hand over to the factory and they can make the changes directly.

Tips:

1.Before installation, check if the installation base is level. If it is not level, it may cause the transformer to deform and affect the sealing performance.

2.Regularly check the oil level. If you find that the oil level is dropping, don't rush to add it. First, find the leak point and then deal with it. Otherwise, adding it will be in vain.

3.If the environmental temperature exceeds 40 degrees, it is recommended to install forced ventilation. Otherwise, even if the heat dissipation tubes
