Waterproof transformers, we can tell from its name that it is one kind of transformer with the function of water proof. So we can know that waterproof transformers are used in the rainy and wet environment. Waterproof transformers have protective casings that the other sensors don’t have. Inside the waterproof transformers,we usually encapsulate heat-conducting epoxy resin. Waterproof transformers can be undivided into many types, such as aluminum casing waterproof transformers, plastic casing waterproof transformers, EI type plastic casing waterproof transformers, wall mounted waterproof transformers and iron casing waterproof transformers, etc. These transformers need to achieve the IP67 level (IP protection standard) for protection.
Waterproof toroidal transformers are mainly used to prevent the rain and water immersion, the power is generally 40VA to 2000VA and the level of protection is IP67. Waterproof toroidal transformers are mainly aimed at the application for rainy open air, water immersion(the pool, river bank, seaside), high humidity of the air.
Toroidal transformer can deal with the possibility of outdoor high temperature environment with the speciality of high efficiency and Low temperature rise. In order to improve the product pressure stabilizing performance and reduce the difficulty of outdoor construction and installation, Ecko waterproof toroidal transformers are usually designed with the function of over load and short-circuit protection. Lead wires of the Ecko waterproof transformers have the cold and ultraviolet resistance dealing with aging wires caused by strong ultraviolet in intense sunlight and the cold outdoor environment in winter.
