2500kVA 20kV Dry Type Transformer 22kV 24kV SCB10 dry type transformer Cast coil transformer manufacturers in China
· Product introduction
SCB10 epoxy resin cast dry-type transformer is an upgrade product of scb9. SCB10 series products features significant high mechanical strength, high electrical strength, high heat resistance and low loss, low noise, low partial discharge. So SCB10 dry-type transformer is environmental protection products for new generation of urban power grid update, and is the mainstream product in the current transformer market. It is especially suitable for commercial center, airport, high building, chemical plant, nuclear power station, ship and other important places requiring fire prevention, explosion-proof and moisture-proof.
This standard defines environment, climate and fire classes and in consequence thereof takes into account varying operating conditions existing at the point of installation.
The climate class takes the lowest ambient temperature into account.
Class C1: Indoor installation not under -5 °C Verification by texting
Class C2: Outdoor installation down to -25 °C Verification by testing
The climate class is thus also a measure for the fracture toughness of the cast-resin compound.
The environment class takes air humidity, condensation and pollution into account.
Class E0: No condensation, negligible pollution
Class E1: Occasional condensation, pollution to a limited extent only Verification by testing
Class E2: Frequent condensation or pollution or both simultaneously Verification by testing
The fire class takes account of the possible consequences of a fire.
Class F0: No provision is made for limitation of the fire hazard Class
F1: Fire hazard is limited as a result of the transformer characteristics Verification by testing.
