Product Description:

This product series is developed on the basis of S13 series, with great reduction of transformer no-load and load losses through thorough upgrade of core materials, optimisation of electromagnetic and temperature field design, and refined manufacturing process control. Compared with the S13 series, the energy efficiency is improved by approximately 15%, leading to substantial savings in electricity costs throughout its entire service life. It is the best choice of the mainstream for the construction of the current distribution network, with the short investment payback period, which is cost-saving and energy-saving. The product adopts a fully sealed corrugated oil tank structure, without the need of an oil conservator, which isolates the insulating oil from the air and moisture, and delays the insulation ageing. This leads to maintenance free operation and maintenance, greatly reducing the user's total lifespan investment. At the same time, the product has the advantages of low noise, strong short-circuit withstand ability and wide adaptability, and is suitable for the power distribution needs of various scenarios such as urban and rural distribution networks, industrial enterprises, commercial buildings and new energy power plants. It is the mainstream designated energy-saving model in the construction of distribution network of power grid companies.

FAQs

 Q1: What are the noise levels and short circuit withstand capabilities of S20-M-10 transformer?

S20-M-10 series transformers are designed with high permeability magnetic cores and optimised lamination technology and structural design, which can fully satisfy the noise requirements of sensitive environments such as residential area, hospital and school. Meanwhile, the product adopts optimised winding structure, high-strength insulating materials and strong fastening design, with extremely strong short-circuit withstand capacity, and can withstand short-circuit impact at the outlet, so that the equipment can operate safely and stably under extreme conditions. 

Q2: What is the energy efficiency of the S20-M-10 transformer? How long does it take to get the difference back on your investment?

A2: The S20-M-10 transformer can reduce the no-load loss by about 15% compared to the S13 series and by about 40% compared to the traditional S11 series, so it can save a lot of electricity costs in its life. The increase in purchase price compared to the S13 series is typically recovered in electricity cost savings within 3-5 years under normal operating conditions for distribution network transformers which results in a more attractive overall life cycle cost. 

Q3. What is the service life of S20-M-10 transformer? But is it actually maintenance free?

A3: The S20-M-10 series transformers use the fully sealed corrugated oil tank design, and new aging-resistant seals with high-quality insulating oil, so the designed service life is more than 30 years. The product eliminates the need for an oil conservator, isolates it completely from air and moisture and significantly slows down the ageing of the insulating oil. No routine core-lifting maintenance or oil changes are required, only periodic visual inspections are needed, which provides truly maintenance-free operation and greatly reduces user maintenance costs. 

Q4: What applications can S20-M-10 transformer be adapted to? What tailor-made solutions do we have?

A4: The S20-M-10 series transformers can be used in many scenarios, including urban and rural power grid transformation, high-end commercial buildings, large industrial parks, data centres, communication base stations, and new energy power plants. We have various customised solutions to meet different application needs, such as rated capacity (100kVA-6300kVA), rated voltage (6-11kV), rated frequency (50Hz/60Hz), multi-level voltage regulation, high-temperature type, low-temperature type, corrosion-resistant type etc.
