?Overview

SC(B) series epoxy cast dry-type transformers are made of electrically oriented silicon steel or amorphous alloy as the core material, and the coils are cast with epoxy resin. They have good fireproof and moisture-proof properties, no pollution, and are flame retardant, self-extinguishing fire prevention. It is a product for urban power grid transformation, especially suitable for urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, underground railways, underground power stations, laboratories, bus stations, docks, airports, combined substations and other important places that require flame retardant, explosion-proof and moisture-proof.

?Structural Features

1.CORE：A three-phase three-column laminated core is used, and the three columns are all covered with windings. The left and right magnetic flux phases are different, the core magnetic circuit is unbalanced, and the middle column magnetic circuit is shorter, which reduces the no-load current.

2.WINDING：It is made of H-class film-coated non-woven flat copper wire and epoxy resin insulating material, which is moisture-proof and corrosion-resistant, has small partial discharge, has sufficient dynamic and thermal stability, and will not shift during operation and transportation.

3.CLAMP：Frame structure, the clamping structure bears the clamping force, the gravity of the lifting body and the mechanical force generated when the transformer is short-circuited, ensuring the electromagnetic performance of the cold-rolled electrical steel sheet.
