Product description

Applications:

Because this 4000KVA oil-immersed transformer adopts the fully sealed structure of corrugated oil tank, it has the characteristics of beautiful appearance, excellent performance and maintenance-free. It can be widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms, oil production platforms, especially suitable for flammable, explosive and other places with high fire protection requirements and harsh environment. Sales Hotline: 13508930968

Features:

1. The core is a seamless and non-graded near-pure circular cross-section made of silicon steel sheet and strip material. The iron yoke, the iron core column is connected to the rounded corner, and the iron core is closed.

2. The high and low voltage coils are directly wound on the core, and the concentricity of the two coils is good, and the ability to resist short circuit is good.

3. Due to the special structure of the iron core, and it is made of crystalline oriented high-quality cold-rolled silicon steel sheet rolled and annealed, the no-load loss of S11-M.R4000KVA oil-immersed transformer is reduced by 30%, the no-load current is reduced by 70%, and the noise is reduced by about 8 decibels compared with the S9 type with the same capacity.

4. Cancel the oil conservator. The corrugated plate oil tank is adopted, and the oil volume change caused by the temperature is adjusted by the elastic adjustment of the corrugated sheet, so that the 4000KVA oil-immersed transformer oil is isolated from the air and prolonged use.

5. The temperature rise of the corrugated fuel tank occupies a small area and the appearance is beautiful.

6. All core processing is mechanized, which reduces labor intensity, improves product quality and stabilizes quality.

Benefits:

1. Stacked with high-quality new cold-rolled oriented silicon steel sheets; H-grade temperature-resistant 180° enameled wire, bare coil winding is beautiful and generous, primary and secondary plus air duct fan heats quickly, galvanized tripod, treated with special dipping process, vacuum dipping, oven drying! The introduction of new processes and technologies such as effectively reducing the vibration and noise during operation, increasing the electrical strength, and adopting the design of high-temperature resistant insulation materials make the 4000KVA oil-immersed transformer more energy-saving and quiet. The energy-saving and low-noise coil has a ventilation groove to allow smooth air flow, which quickly and effectively reduces the temperature of the coil. Sales Hotline: 13508930968
