Basic Features

1000 kVA 11kV / 0.4kV Oil-Immersed Distribution Transformer is mainly composed of core, winding, oil tank and cooling system. Its core principle is electromagnetic induction: alternating current is applied to the primary winding to generate a changing magnetic field, and the secondary winding induces alternating current of the same frequency in the magnetic field, thereby realizing voltage increase or decrease. Transformer oil, as an insulating medium, not only plays a cooling role, but also prevents winding oxidation.

Product Advantages

This transformer has a rated capacity of 1000 kVA and can carry high-power electrical loads, fully meeting the power supply needs of large factories with multiple production lines, commercial complexes operating at full load, large charging pile clusters and other scenarios. At the same time, compared with larger-capacity models, it is also suitable for small and medium-sized distribution occasions, effectively avoiding capacity redundancy and waste. The equipment has excellent overall reliability, can adapt to complex power grid conditions, and achieve long-term stable operation.

Application

Residential Applications

Suitable for high power electrical appliances or household power system upgrades.

Office Environment

Supplies stable power to large office equipment, server rooms, etc.

Industrial Use

Used for factory equipment, machinery and other high-power demand occasions.

Selection Precautions

  1. Load characteristics: If the equipment operates continuously, such as motors, overload capacity should be considered; if it is intermittent load, such as air conditioners, the selected capacity can be appropriately reduced.
  2. Environmental factors: For outdoor installation, products with a protection level above IP23 should be selected to avoid rainwater and dust intrusion; in high-altitude areas, insulation strength adjustment should be noted.
  3. Energy efficiency standards: Give priority to energy-saving transformers. No-load loss is about 20% lower than traditional models, which can save electricity costs in long-term operation.
  4. Installation specifications: The transformer foundation should be more than 30 cm above the ground, and no debris should be stacked within 1 meter around it to ensure good heat dissipation.

About Distribution Transformer Certification

In a small project of a 1000 kVA 11kV / 0.4kV Oil-Immersed Distribution Transformer that we concluded with a Pakistani customer, in addition to the overall qualifications, the customer also put forward corresponding requirements for product accessories, such as temperature rise test report, on-load tap changer sample, testing, gas, temperature, temperature control, oil level, alarm panel/control box, and transformer protection test report. Besides the certification of the whole transformer, the customer still needed experimental reports and inspection reports for the accessories. In this regard, CHBEB also solemnly promises to customers and potential buyers in front of the webpage that everything serves customer needs. We are a distribution equipment manufacturing company with solid quality. Please firmly believe in the power of the brand.

In addition, recently we have also noticed that many customers are urgently concerned about delivery time. CHBEB transformers have 30 years of accumulation, fast production line response, and flexible scheduling process. Except for some fixed logistics time, the average delivery time is about 5 working days shorter than that of ordinary companies in the industry. Welcome to inquire.
