Product Overview
The SCBZ11 dry-type transformer we produce adopts high-quality epoxy resin vacuum casting process. Its coil is completely wrapped by the insulation layer, making the transformer moisture-proof and anti-fouling, which is very suitable for harsh operating environments with high humidity, dust and other serious pollution. In addition, our transformer windings will undergo a strict 72-hour salt spray cycle test before leaving the factory. Whether it is high-rise buildings, subway tunnels, airports, data centers, hospitals and other places, this transformer is an ideal choice for these high-security sensitive places.

Product Features
High efficiency and energy saving
Our dry-type transformer uses high-quality silicon steel sheets and epoxy resin casting technology. The no-load loss is reduced by more than 15% compared with traditional models, and the load loss is optimized by 10%. The overall energy efficiency is significantly improved, which can effectively reduce operating costs.
Safety and environmental protection
Our on-load voltage-regulating epoxy cast dry-type transformer uses flame-retardant epoxy resin insulation material. When exposed to open flames, it will self-extinguish and not support combustion. It meets the requirements of relevant standards and can effectively reduce the risk of fire.
Good moisture-proof and corrosion-resistant performance
The conductors of our transformer windings are encapsulated by a solid epoxy resin insulation layer, which makes it difficult for moisture to penetrate and also blocks the conductors from being attacked by harmful gases and corrosive chemicals. They can operate reliably in high humidity environments or places with corrosive gases.

Note:
The load losses listed in the table are the values of different insulation systems at the reference temperature shown in brackets (see GB1094.11). For load losses at other insulation system temperatures not included in the table, the data of the 155℃ (F) insulation system should be used as a reference and appropriate conversion should be performed according to the respective reference temperatures.
FAQ
Q: How long is the delivery time?
A: Normal within 10 days. It depends on detail items and quantity.Please contact us for details.
Q: How to get product quotation?
A: You can contact us anytime through the contact information on the website. You will receive our response within 24 hours.
Q: What after-sales services can I enjoy?

Q: How long is the average lifespan of a transformer?
A: The lifespan ranges from 20 to 40 years, influenced by factors such as maintenance level, operating environment, and load conditions.
Q: How to determine the parameters of the transformer?
A: We can usually find the parameters in transformer nameplates, drawings, outline drawings, and technical tables.
Q: Do you have oil-immersed transformers and dry-type transformers in stock?
A: No, as transformers require customized parameters based on demand, we usually need to design them after receiving an order.
