dry type distribution transformer-6-10 KV SCB series epoxy resin cast
Product Features
Resin insulation dry-type transformer is an advanced foreign technology introduced by our company.We independently developed series of thin-walled dry-type transformers with fillers,such as SC(B)10,SC(B)11,SC(B)12 and SC(B)13.Because the coil is encapsulated by epoxy resin,it is flame-retardant,fire-proof,explosion-proof, maintenance-free,pollution-free and small in size,and can be directly installed in the load center.At the same time,the scientific and reasonable design and pouring technology make the product have smaller local discharge,low noise and strong heat dissipation ability, is equipped with intelligent temperature controller, which has the functions of fault alarm,over-temperature alarm,over-temperature trip and black brake,and is connected with computer through RS485 serial interface, so it can be monitored and controlled centrally.Because our dry-type transformer has the above characteristics,it is widely used in power transmission and transformation systems,such as hotels,airports,high-rise buildings,commercial centers,residential quarters and other important places,as well as subways,smelting power plants, ships,offshore drilling platforms and other places with harsh environment.
