KYN28A-12 metal-clad withdrawable switchgear

12 kV switchgear for the incoming and outgoing feeders of a 10 kV substation, with the interlocking and test documentation a project needs.

What it is

The switchboard between the transformer and the network

KYN28A-12 is a metal-clad, metal-enclosed withdrawable switchgear: the circuit breaker sits on a withdrawable truck, so it can be racked out for maintenance without exposing the busbar compartment. Each compartment is segregated, and the mechanical interlocks prevent the breaker being moved with the circuit live.

We build it together with the transformers and packaged substations on the same site, which means the interface dimensions, cable entries and protection settings are resolved before the equipment leaves the factory.

KYN28A-12 questions

Question	Answer
Can it be supplied with the transformer as one package?	Yes. It is normally built into the packaged substation, or supplied loose for site assembly.
Do you provide the type test report?	Yes, for the type. Send the project standard and we will confirm the report matches it.
What is the MOQ?	Quoted per project; switchgear is usually ordered with the transformers rather than on its own.
What are the payment terms?	T/T 30% deposit, 70% before shipment; L/C at sight for tender orders.
