SCB14 cast-resin dry-type transformers, 30 to 2500 kVA

No oil, no fire load. For indoor substations where an oil-immersed unit is not acceptable, at Class-2 energy efficiency.

Why dry-type

When the transformer sits inside the building

In a factory, a shopping centre or an office building, an oil-filled transformer brings fire load, oil containment and ventilation requirements that the building design has to carry. A cast-resin dry-type unit removes most of that: the windings are sealed in epoxy, there is no oil to contain, and the unit can sit closer to occupied space.

SCB14 is the Class-2 efficiency version of our cast-resin range. If your specification scores losses, ask about SCB18 for Class-1.

Where it is used

Factory substations

Renewable converter stations

Step-up and station service duty inside wind and solar plants.

SCB14 questions

Question	Answer
Difference between SCB14 and SCB18?	Same platform, different loss level. SCB18 is Class-1 efficiency and costs more; SCB14 is Class-2.
Can it be installed outdoors?	Only in an enclosure that suits the site. Dry-type units are normally indoor; for outdoor duty we would usually propose a packaged substation.
Do you supply the type test report?	Yes, for the series, on request. Every unit also gets a routine test record.
What is the MOQ and lead time?	10 units per order. Lead time quoted per order; it depends on the rating mix.
What are the payment terms?	T/T 30% deposit, 70% before shipment; L/C at sight for tender orders.
