Product details

Environmentally Friendly SC(B)10-13 Dry-Type Transformer

Premium Dry Type Three-Phase Transformer for Reliable Power Supply
Our Dry type power transformers are meticulously engineered for excellence, seamlessly blending cutting-edge electrical engineering with state-of-the-art manufacturing techniques. These transformers belong to the esteemed SC(B)10, SC(B)11, and SC(B)13 series, purposefully designed to meet the ever-evolving demands of modern power distribution with unparalleled efficiency, safety, and minimal environmental impact. By incorporating advanced features and adhering to stringent quality standards, our transformers provide a reliable and sustainable power solution for a wide range of applications.
The versatility of our Dry type transformers allows them to be deployed across a diverse range of settings, including:
(1) High insulation strength: The epoxy resin used for casting has an insulation breakdown field strength of 18~22kV/mm, and has roughly the same lightning impulse strength as the oil-immersed transformer of the same voltage level.
(2) Strong short-circuit resistance: Due to the material properties of the resin and the fact that the winding is cast as a whole, it becomes a rigid body after being heated and cured, so the mechanical strength is very high. The sudden short-circuit test has proved that cast dry-type transformers are rarely damaged by short circuits.
(3) Outstanding disaster prevention performance: Epoxy resin is flame-retardant and can extinguish itself, so it will not cause secondary disasters such as explosions. (4) Excellent environmental performance: Epoxy resin is a chemically extremely stable material that is moisture-proof and dust-proof. It can operate reliably even in harsh environments such as polluted air, and can even operate normally at 100% humidity. It 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, epoxy cast dry-type transformers can now be maintenance-free, which can greatly reduce the burden on operators and reduce operating costs.
(6) Low operating loss and high operating efficiency.
(7) Low noise.
(8) Small size, light weight, easy installation and commissioning.
(9) No need for a separate transformer room, no need for hanging core maintenance, saving floor space and correspondingly saving civil engineering investment. 3. Epoxy resin cast dry-type transformer production process.

Technical features

The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, 45° full-bevel joints, five-step lamination method, and the core column and iron yoke are both multi-stage circular cross-section shapes, which can obtain smaller no-load loss and lower noise.
Each phase is equipped with an independent axial flow fan and a split temperature controller to effectively reduce temperature rise, increase transformer output capacity, and ensure safe operation of the transformer.

Product advantages

Good fire resistance, low loss, low noise, no pollution, maintenance-free, strong short-circuit resistance, small size, and light weight.
