Oil Immersed Non-excitation Tap-changing Transformer of 35kV and Below
Tap-changing Transformer of 35kV and Below
This kind of product is applied to power system of three-phase, 50Hz as well as
35kV and below, it is the main transformer equipment of medium and small-sized
transformer substation, supplies power distribution, power and illumination for
the industry and agriculture.
The company introduces in domestic and overseas advanced technique, adopts
the latest material and optimizes design, which enables the product structure
more reasonable, and greatly improves the product electric strength, mechanical
strength and heat-sinking capability. S9 series product has passed the short-circuit
test prepared by Wuhan High Voltage Research Institute and also the test
prepared by National Center for Quality Supervision & Test of Transformer.
1.Iron core The iron core is made of high quality cold rolled silicon steel sheet, adopts the kinds of types like full-bias multi-step seam, no punched hole, winding iron core, etc., besides, both stainless steel stay plate and epoxy glass belt are for clamping it.
