Pouring solid
1.The high-and-low voltage system are cast under vacuum, thus the coil will not absorb moisture.
2.Flame retardancy, explosion-poof and no environment contamination.
3.Gas duct is embedded inside it to enhance the radiation power and over-load capacity.
4.Low loss and low noise.
5.It highly withstands short-circuit and lightning impact.
6.Small in volume, light in weight, safe in running and free of maintenance.
7.As per user’s requirements the transformer may be provided with casing and blower fan.
Safety
Model SG(B) new products are dry transformer with the highest safety in current market. All of tis insulating materials are of non-combustion supporting , self-extinguishing, nontoxic one. It shows advantages especially when used in those fields where high safety is required, humidity and temperature are high , and ventilation is poor, such as in power sites, underground railways, ships, chemical and metallurgical sites. Outer casing and blower fan cab be provided if required by users.
Reliability
The coil of model SG(B) is specially designed and made of special material with special technical process, which renders the product excellent moisture-proof, mildew-proof and salty fog-proof performances, much higher temperature endurance, and permanent chap-free ability. The Nomex-based insulating system can remains at the extraordinary excellent and mechanical performances and compressive strength, therefore its coil can keep a compact and tight structure after many years’ service and the transformer can withstand short-circuit voltage.
Environmental protection
Model SG(B) product can be disassembled for recovery after life-end, thus meeting clients’ requirements one environmental protection. While those dry transformers made via epoxy cast can’t be disassembled , because the resin glass has cured into an integral one , and therefore is unfavorable for environmental protection.
Strong overload capacity
Model SG(B) adopts new structure, novel material and up-to-date technology, featuring good heat-sinking capability, long thermal endurance, strong overload capability, it can run stably under 120% rated load for a long period. It can keep a long term running under full-load in IP23 environment without forced air ventilation necessary.
