Dry-type Power Transformer Dry-type Power Transformer Product Description Dry-type transformers   are widely used in local lighting, high-rise buildings, airports, docks CNC machinery and other places, simply that dry-type transformers refers to the core and the winding is not immersed in the insulating oil transformer. Cooling is divided into natural air cooling (AN) and forced air cooling (AF). Natural air-cooled, the transformer can be rated for long-term continuous operation. Forced air-cooled, the transformer output capacity can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation. Due to the large increase of load loss and impedance voltage during overload, it should not be in continuous non-economic operation for a long time. Construction performance： 1.Solid insulation wrapped winding 2.Not wrapped around the winding Winding the two windings, the voltage is higher voltage winding, the lower is the low voltage windin

High Insulation Materials Insulating materials in the early 20th century, with the development of European and American electrical industry with the emergence of the modern electrical industry “vascular and heart” of the main components. It’s very commoto see in our daily life like “wire layer indoor”, “inside and outside wall insulation sleeve”, “Touch and low-voltage electrical plastic”, “height of the insulator,” etc., are of insulating materials, but these only the “tip of the iceberg. More precise definition of insulating materials are: volume resistivity of the material 109 ~ 1020 Ω • m posed by substances in electrical insulating materials is technically called, also known as the dielectric. The insulating material has a very large direct current resistance, in the DC voltage applied, in addition to the outer surface leakage tiny, virtually nonconductive, and for alternating current through the capacitive current, but is not considered conductiv. In long-term use of insul

High Voltage Insulation Materials according to generally as the points, solid insulation materials commonly used in pipe insulation, laminates, insulation film, insulation paper , rubber, plastics, glass, ceramics, mica, etc.; liquid materials are insulating paint, glue, resin, transformer oil, and the liquid material is often a pre-semi solid material; material with nitrogen gas, sulfur hexafluoride. Classification according to degree of heat is one of the most professional classification;Insulation material is divided into A, E, B, F, H, C and other levels, each corresponding temperature heat levels as follows Class A insulation — temperature 105 ℃, Class E insulation — temperature 120 ℃, Class B insulation — temperature 130 ℃, Class F insulation — temperature 155 ℃, Class H insulation — temperature 180 ℃, Class C insulation — temperature above 200 ℃ Insulation performance and stability of insulation materials will get worse, If the temperature get higher.
