Epoxy Resin Cast Dry Type Distribution Transformer
Welcome to purchase this Epoxy Resin Cast Dry Type Distribution Transformer from Ceho factory. As the coils of the resin-insulated dry-type transformer are encapsulated by the epoxy resin, they are nonflammable, fireproof, explosion-proof, maintenance-free, no pollution, small volume, and can be installed in the load center directly. Meanwhile, the scientific and reasonable design and casting technology enable the products to have lower discharge capacity, low noise and strong heat dissipation. This product are able to run for a long time under 140% rated load under forced air cooling condition. Besides, the dry type transformer are equipped with intelligent temperature controllers, have functions of trouble alarm, over temperature alarm, over-temperature tripping and black box, can be connected with the computer through RS485 serial interface to realize centralized monitoring and control.
This Epoxy Resin Cast Dry Type Distribution Transformer is safe, pollution-free, and flame-retardant. It can be directly installed at the load center and offers advantages such as maintenance-free operation, easy installation, low overall operating costs, low losses, and excellent moisture resistance. Ceho transformer can operate normally at 100% humidity and can be put into use without pre-drying when idle. It features low partial discharge, low noise, and strong heat dissipation, and can withstand 120% of its rated load under forced air cooling conditions.

Design and Manufacturing Process
Based on over 320 years of experience in transformer design, manufacturing, and testing, CEHO has developed an advanced 3D+parametric design software capable of automated design, cost optimization, and simulation.
Fully considering national and industry standards, we ensure superior product design.
The high-voltage winding conductors are made of high-quality conductors and reinforced with chopped glass fiber felt. An advanced Heydrich vacuum casting system is used for casting under vacuum conditions, effectively suppressing partial discharge (PDF) with a PDF rate ≤5pc.
The low-voltage winding uses high-quality foil conductors and is wound on an automatic foil winding machine. This machine employs a patented hydraulic energy-saving tension crimping device with a detection accuracy of ±0.5mm and advanced argon arc welding technology, playing a crucial role in ensuring coil winding quality.
The core of the Epoxy Resin Cast Dry Type Distribution Transformer transformer uses high-quality, high-permeability oriented silicon steel sheets, treated with a 45° full-bevel grinding process, and coated with a special moisture-proof and rust-proof coating, effectively reducing no-load current and noise levels.
