Epoxy Resin Cast Dry Type Transformer SCB14-500

Resin-Insulated Dry Type Power Transformer

Epoxy Resin Cast Dry Type Transformer SCB14-500

Epoxy resin is a widely used chemical raw materials, it is not only a flame retardant, flame retardant material, and has superior electrical properties, and then gradually used by the electrical manufacturing industry. Because epoxy resin has high insulation strength compared with air and transformer oil, and has high mechanical strength and superior moisture and dust resistance after pouring, it is particularly suitable for the manufacture of dry transformers.

    Characteristics Of Epoxy Cast Dry Transformer

    (1) High insulation strength: the epoxy resin for casting has an insulation breakdown field strength of 18~22kV/mm, and the oil immersion with the same voltage level has roughly the same lightning impact strength.

    (2) Strong short-circuit resistance: due to the material characteristics of the resin, coupled with the winding is the whole pouring, after heating curing molding into a rigid body, so the mechanical strength is very high, the sudden short circuit test proved that the poured dry transformer due to short circuit damage is very little.

    (3) Outstanding disaster prevention performance: epoxy resin flame retardant, flame retardant and can self-extinguish, will not cause explosion and other secondary disasters.

    (4) Superior environmental performance: epoxy resin is a chemically extremely stable material, moisture-proof, dust-proof, even in harsh environments such as atmospheric pollution can operate reliably, and can even operate normally at 100% humidity, and can be put into operation again without drying and preheating after shutdown.

    (5) maintenance-free: Due to the perfect temperature control and temperature display system, the current epoxy cast dry transformer can be maintenance-free, which can greatly reduce the burden of operators and reduce operating costs.

    (6) Low operating loss, high operating efficiency.

    (7) Low noise.

    (8) Small size, light weight, convenient installation and debugging.

    (9) No separate transformer room is required, no core maintenance is required, the floor area is saved, and the civil construction investment is saved accordingly.
