10kV 2500 KVA Corrugated Tank Hermetically Sealed Oil Filled Distribution Oil Immersed Transformer

Product Advantage

 Performance Characteristics

Compared with the "9" type transformer, the no-load loss of this transformer is reduced by about 30% on average. Compared with JB/T10088-1999 standard, the noise is small, and the noise is reduced by about 7dB. The temperature rise of the oil level and high and low pressure windings is about 20K-13K lower than the temperature rise limit, and there is a certain overload capacity. Strong resistance to short circuits and high reliability.

 Structural Features

◇ Iron core

Three-phase three-column inner and outer frame rolling structure, the core column is a multi-step stepped circular section; After the core is rolled, the stress is removed by vacuum annealing; grooved bending clamps, pulling screw tensioner body; The surface of the iron core is coated with special glue to ensure that the iron core does not deform and rust.

◇ Winding and body

Low-voltage winding is 1~6 wires wound four-layer or double-layer cylindrical (500kVA and below) or spiral (630kVA and above) winding; The wires are drawn from oxygen-free copper; The interlayer insulation of high and low voltage windings is Linger dispensing paper; The oil gap between the axial oil passage of the high pressure winding and the main airway between high and low pressure is the structure of the brace curtain; The yoke insulation and the trapezoidal pad are integrated to evenly compress the body; The body adopts a new hanging plate positioning structure, longitudinal and transverse positioning to ensure that the body is stable and not displaced.

◇ Fuel tank

Corrugated oil tank sealed structure, no oil leakage, maintenance-free.

Technical Parameters

Product Uses

Here are five specific application scenarios of Transformers:

1. Commercial Complexes & High-Rise Residential

Modern commercial complexes and high-rise residential buildings require reliable, compact, and fire-safe power distribution equipment.

2. Industrial Parks & Heavy Manufacturing

Industrial parks and heavy manufacturing facilities, including steel mills, cement plants, chemical factories, and automotive assembly lines, consume large volumes of medium-voltage power and require robust, outdoor-rated distribution equipment.

3. PV & Energy Storage Grid Connection

Solar photovoltaic farms and battery energy storage systems (BESS) require dedicated step-up transformer solutions to interface with the medium-voltage grid.

4. Infrastructure — Rail Transit, Healthcare & Data Centers

Critical infrastructure applications, including metro and railway systems, hospitals, and data centers, demand the highest levels of power reliability and redundancy.

5. Municipal & Environmental — Water Treatment & Pumping Stations

Municipal water supply, wastewater treatment plants, and flood control pumping stations present challenging operating conditions for electrical distribution equipment. altitude not more than 1000m;
