Indoor & Outdoor Dry Type Transformers.


Dry type transformers require absolute minimum maintenance to provide long-lasting of reliable hassle-free service. A dry-type transformer has no moving parts and maybe a completely static solid-state device, under normal operating conditions, usually ensures an extended and hassle-free life. Normally liquid fill transformers which are cooled with oil, dry-type units utilize only environmentally safe. Dry type transformers provide a safe and reliable power source which does not require fireproof vaults, cast reins are enough. By ensuring the safety factors allow the installation of dry type transformers inside buildings on the brink of the load, which improves overall system regulation and reduces costly secondary line losses.

Cast resin transformers are compatible for installation in Multi-storied buildings, underground tunnels, hospitals, school, steel factories, chemical plants and places where fire safety may be a great concern. Hazard liberal to the environment, dry type transformers have over the years proven to be highly reliable. Dry type transformers are automatically cooled by normal air ventilation. The dry type transformer doesn't require a liquid like oil or silicone or the other liquid to chill the electrical core and coils. Dry type transformers are voltage changing (Step-up or Step-down) or isolation device that's air-cooled instead of liquid-cooled. The transformer case is ventilated to permit air to flow and cool the coil (coils).

Dry type transformers differ from liquid-filled units in some ways, and separate industry standards apply to their design, construction, and maintenance. Dry-Type Transformers are suitable for indoor and outdoor applications. Cooling ducts within the windings allow heat to be dissipated into the air. Dry-types can operate indoors under almost all friendly conditions for commercial buildings and light manufacturing facilities. For outdoor operations, a dry-type transformer's enclosure will usually have louvres for ventilation. But, these transformers can be affected by hostile environments like dirt, moisture, corrosive fumes, conductive dust, etc. because the windings are exposed to the air. Other approaches to putting together dry-type transformers for harsh environments include cast coil units, cast resin units, and vacuum pressure encapsulated (VPE) units, sometimes employing a silicone varnish.
