Huarui Custom D11 D13-Bm-10kVA-10/0.23kv Oil-Immersed Single Phase Overhead Pole Mounted Transformer Price

Liaocheng HUARUI Electric Co., Ltd. established in 1996,located in Liaocheng City, Shandong Province, which is one of the shortlisted suppliers of State Grid Corporation of China and belonging to a national high-tech enterprise.


HUARUI Electric is engaged in the research and development, production and operation of dry-type transformers of 35kV and below, combined transformers, prefabricated substations, transmission and distribution and Control equipment, etc. The annual output of transformers exceed 5 million kVA, and the pad-mounted products exceed 2000 sets.

HUARUI Electric occupies a factory area of 17 hectares, with more than 6 hectares of modern factory building. HUARUI Electric has almost than 200 employees and more than 150 sets of specialized manufacturing equipment.

We have established a sound quality management system, and have passed the certification of ISO9001:2015 quality management system, ISO14001:2015 environmental management system, and ISO45001:2018 occupational health and safety management system.

In order to ensure product quality and in order to meet the development and supply of our dry-type/oil-immersed transformers in overseas international markets, we all participate in type and special tests of internationally recognized independent testing laboratories, and obtain relevant reports.

Core:

1. The core is made of high quality grain-oriented cold-rollled silicon steel of high magnetic conductivity, by using 45°five-step overlapping method to reduce the no-load loss and no-load current.

2. Simulation analysis method is applied for the core design, thus to precisely and effectively calculate the vibration frequency and scale.

3. Flexible connections are adopted between the core and coils, core and clamps. With these measures, transformer's noise level has been improved by 10-15dB over the conventional products.

LV Winding:

1.LV windings are adopting superior foil conductors or made of 100% copper wire, thus to obtain better amperturn balance and reduce more transverse magnetic flux leakage. Then to greatly improves transformer's anti-short circuit capability.

2. Excellent design of oil passage structure, greatly increasing the coils' heat dispersion effect. It helps to decrease temperature rise of the LV winding and improve transformers' overload capability.

HV windings

1. HV windings are manufactured with superior wire conductors, insulated reinforced with fiber glass.

2. The HV windings are cast under vacuum and high pressure conditions resulting the best resin penetration and very low partial discharge( partial discharge for 11kV product could be lower than 5Pc).

3. Optimized structure is adopted for HV windings to improve transformer's electric field. Lighting impulse simulation calculation was adopted for winding model design, thus to substantially improve product's anti-lighting capability.

Tank:

1.The tank is jointed with highquality steel. The surface is eliminated rust phosphate coating and painted with the type of FVC anticorrosive paint.

2.It has ability to prevent the corrosion from oil and chemical matter. It can be broadly applied to outdoors with bad environment for its contour artistic, easily installation and maintenance free.
