100kva electrical power transformer price Ai Power offers three phases, oil immersed, and naturally cooled distribution and power transformers. Our products from 10kva to 20000kva with a maximum voltage 35kv are manufacture under the standard of IEC60076. The windings are made of high-grade electrolytic cooper and are concentrically positioned. Usually copper foil is used for the low voltage windings. Round shaped, enamel insulated wires is used for the high voltage windings.
Introduction: Our transformers had exported to more than 50 countries in the world up to 200mva 230kv, we offers a complete range of power and distribution transformers designed to grant the reliability, durability, and efficiency required in utility, industrial, and commercial applications. QingZhong is a major transformer manufacturer throughout China offers both liquid-filled and dry-type transformers as well as services for complete life-cycle support, including replacement parts and components.
Excellent Materials: 1.Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformador is lower and the electric performance is better. 2.High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformadores is lower. 3.High-quality wooden laminating insulation pieces, which wonâ??t split or move even under the influence of short circuit. 4.Thoroughly filtrated transformadores oil containing less water, gas and impurities, which makes our transformador es work better. 5.High-quality rubber sealing material, which can prevent the transformadores form aging. url:http://www.ybtransformer.com

1. Ambient air temperature: -5oC~+40oC, the highest monthly mean temperature should not exceed +30oC; 2. Altitude for installing place should not exceed 1000m; 3. When the ambient air temperature is +40, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperatures. Max's average humidity in the dampest month is 90%, meanwhile, the lowest average temperature of this month is +25oC, and condensation on the product surface caused by temperature change should be taken into consideration.
