The main purpose of the waterproof transformer is to prevent rain or water soaking. The capacity is generally 10VA to 10kVA, and the protection level is IP67. The waterproof transformer is specially designed for outdoor rain shower (outdoor wall hanging), water soaking (pool, river, seaside), air humidity and other application occasions. In order to cope with the high temperature environment that may occur outdoors, the transformer adopts the ring transformer, which has the advantages of high efficiency and low temperature rise. Protective housing (outer housing) generally no longer use iron and plastic shell, but use aluminum shell to facilitate heat dissipation; In order to improve the product voltage stability performance and reduce the difficulty of outdoor construction and installation, the ring waterproof transformer is generally designed with overload and short circuit protection functions; In order to cope with the wire aging caused by the strong ultraviolet in the strong sunlight during the day, and the cold outdoor temperature in the northern winter environment, the input and output leads must use wire with cold resistance and uv resistance characteristics.

The transformer is made of silicon steel with high magnetic flux and low loss and double insulation and high strength enameled wire. 1. Long life power supply: thermal conductive epoxy resin is completely sealed; 2. Safe power supply: dustproof, moisture-proof and waterproof; 3. High efficiency power supply: higher energy conversion efficiency; 4. High standard design: double insulation enamelled wire winding;High quality process: 5. Standardized winding process and welding level.

Ring waterproof transformer is specially designed for outdoor rain shower (outdoor wall hanging), water immersion (pool, river, sea), air humidity, etc. Toroidal waterproof transformer is designed with overload and short circuit protection. In order to cope with the wire aging caused by the strong ultraviolet in the strong sunlight during the day, and the cold outdoor temperature in the northern winter environment, the input and output leads must use wire with cold resistance and uv resistance characteristics.

Waterproof transformer is a transformer with waterproof (moisture-proof/rainproof) function.Waterproof transformer has a special protective shell (outer cover), and the internal transformer is treated with pouring and sealing (generally using thermal conductivity epoxy resin as the pouring and sealing material), which can deal with high temperature, humidity, rain, water immersion and other harsh environment. IP protection grade is relatively high (IP67). When used as outdoor, environmental factors change greatly, transformer must have heat dissipation performance, high temperature resistance, cold resistance, uv resistance requirements, considering outdoor construction and installation use, general requirements with overload and short circuit protection. Waterproof transformer has been widely used in outdoor lighting, urban lighting engineering, mining, Marine equipment, electronic sanitary equipment, industrial atomization humidifier, medical equipment, precision instruments and other industries.
