Low-voltage transformer products are composed of casting body (housing), secondary outlet box (including secondary wiring terminals), installation board and other parts.

The body and the epoxy resin mixture are integrally cast or assembled in a sealed plastic housing, and the secondary terminals are directly lead out from the casting body. There is polyester film inside as insulation, and the insulation strength is high. The use of a fully enclosed iron core effectively ensures the stability of product errors. The outside of the secondary terminal is covered with a transparent junction box that can be sealed with lead, which is well sealed and effectively prevents electricity stealing.
