Pouring epoxy resin inside waterproof transformer,mainly because the epoxy resin has excellent adhesion strength to the surface of metal and non-metallic materials, good dielectric properties and thermal conductivity, which can bring the following benefits to the waterproof transformer:
1. Quakeproof.
It can effectively reduce the vibration produced during the operation of the internal ring transformer, so as to play a shockproof effect.
2. Helps the transformer dissipate heat.
The toroidal transformer is sealed and installed in the waterproof shell, which will generate heat and temperature rise when it operates. If the heat generated by the transformer can not be effectively dissipated, the transformer is easy to burn down. This problem can be solved by pouring epoxy resin, because epoxy resin has good dielectric and thermal conductivity, which is conducive to heat conduction and heat dissipation.
3. Improve the waterproof effect of waterproof transformer.
Pouring epoxy resin can improve the waterproof effect of waterproof transformer. For example, the aluminum shell waterproof transformer can reach the waterproof level of IP67 by pouring epoxy resin. Even if it is immersed in the water for a long time, it can ensure that the water does not enter the aluminum shell.
Waterproof transformer is generally used in outdoor landscape, outdoor engineering lighting, underwater lights and other places with waterproof or moisture-proof requirements.
