ypes of Power Transformers & Mini Substation for Sale
ZJYB main types of power distribution transformersare oil immersed power transformer, epoxy resin dry type transformer, combined transformer substation, etc.
Advanced testing and inspection equipment, strict production process and perfect testing and inspection process are the powerful backing of our product quality, and also the confidence source of YUEBIAN distribution power transformers export.
Our distribution transformers havepassed ISO9001 quality management system certification, product quality in line with IEC60076 international standards and national standards.
Oil Immersed Transformer
The oil insulated distribution is fully oil-filled distribution power transformer. The corrugated fuel tank bright body is a permanently sealed oil tank with its own elasticity to adapt to the expansion of the oil, and has been widely used in various power distribution equipment. The core material is selected from cold-rolled silicon steel sheets.
Dry Type Transformer
The dry type transformer is called an epoxy resin casting distribution transformers productsand uses epoxy resin as an insulating material. The high and low voltage windings are made of copper strip (foil). The epoxy is cast and cured in a vacuum to form a high strength FRP structure. The insulation grade is F and H. Epoxy dry-type transformer has the characteristics of good electrical performance, strong anti-lightning capability, strong short-circuit resistance and light weight. A temperature display controller can be installed to display and control the operating temperature of the transformer windings to ensure the normal life of the transformer.
Dry TransformerVs Oil Transformer
COOLING MEDIUM
Dry-type transformers use air as the cooling medium, while oil-filled transformers use oil instead of air.
MAINTENANCE
Generally, oil-filled transformers require maintenance procedures to be performed more often than with dry-type transformers.
PRICE
Oil-filled transformers are generally cheaper than the dry cast resin transformers, with some exceptions.
SOUND OPERATING LEVEL
Transformers are generally known for being noisy when they are running. With that being said, oil insulated transformer are quieter than the dry-type ones.
EFFICIENCY
Oil-filled transformers are known to be more efficient than dry-type transformers, which are limited in their voltage rating and their size.
Mini Substation
The power electrical transformers chinaused in substation includes high-voltage power distribution device, transformer and low-voltage power distribution device. With various substation equipment for sale, we divided electrical distribution transformer into three functional compartments, namely high-voltage room, transformer room and low-voltage room. The high and low voltage rooms are fully functional, and the high-voltage side primary power supply system can It is arranged in a variety of power supply modes such as ring network power supply, terminal power supply, dual power supply, etc. It can also be equipped with high-voltage metering components to meet the needs of high-voltage metering. The variable pressure chamber can be selected from oil-immersed transformers or dry-type transformers; the low-voltage chamber can be assembled according to user requirements by panel or cabinet-mounted structure, and has power supply and lighting distribution. Various functions such as reactive power compensation, energy metering and power testing meet the different requirements of users. And convenient for the user's power management and improve the quality of power supply.
