YD series oil-immersed test transformer is mass produced based on same type and after a large of improvement according to electromechanical department (test transformer) standard, YD (JZ) series light type AC/DC high-voltage test transformer is new type product produced and after improvements based on YDJ series test transformer and according to national standard (JB∕T 9641-1999). This series product has small size, light weight, tight structure, multi-functional, big versatility and convenient use characters etc. Especially it is suitable for electric power system, industrial and mining enterprises, scientific research departments etc which do insulation test in power frequency and DC high-voltage to high-voltage electric equipment, electric component and insulating material. It is necessary equipment in high-voltage test.
Features:
1, This series product is iron lead and single phase, it is made of high quality cold-rolled oriented silicon steel plate stacked and using steel clamps for fastening means.
2, Cylinder multi-storey tower type of Test transformer HV coil, winding by polyester enamelled wire and high and resistant voltage insulation materials.
3, Low-voltage coil is outside, meter coil is an independent coil windings, normally it is 100v.
4, Shell is octagonal and movable wheels are equipped on over 10kVA testing transformer with light weight, small size, easy to move, superior performance etc characteristics.
