What does Jinjia Power manufacture?

Diesel and gas generator sets from 3 kW to 3000 kW, plus the components that go around them: marine generators, mobile trailer sets, fire pump generators, AC alternators, alternator parts, voltage regulators, generator controls and generator ends.

Which engine brands can I specify?

Cummins, Perkins, Volvo, MTU, Mitsubishi, SDEC (Shangchai), Weichai, Yuchai, Yangdong and Isuzu. The engine is chosen for parts support in the destination country as much as for output, so tell us where the set will run and we will narrow the list.

Which alternators and controllers do you fit?

Stamford, Leroy Somer or Marathon alternators, with Deep Sea or SmartGen controllers and a matched automatic voltage regulator. These are the components that decide voltage stability and whether the set can be paralleled later.

Are you a factory or a trading company?

A manufacturer, assembling in Dongguan, Guangdong since 2011, with established assembly capacity and 5000+ clients in 50+ countries. Because we assemble and load-test on our own floor rather than resell sealed units, a non-standard kVA rating, a dual-frequency 50/60 Hz output or a containerised package does not carry the lead time a distributor would add.

Is every set tested before shipment?

Yes. Every set is load-bank tested at 100 per cent rated output before it ships, and the test record travels with the set. That record is the baseline against which any later performance question is judged.

How fast can you ship?

Most stocked ratings ship within days, and the standard window for an order is three to seven days depending on the rating and the enclosure. Non-standard builds are made to order, so confirm the rating before the ship date is fixed.

Can you build a rating that is not in the catalogue?

Yes, from 3 kW to 3000 kW to specification. Send the standby kVA or prime kW, the voltage and frequency, the enclosure type and the ambient conditions, and we will quote the frame that matches rather than the nearest catalogue page.

What do you need from me to get a quote?

The standby kVA or prime kW you are sizing against, the voltage and frequency, the enclosure type, and the destination country. With those you get a firm quote naming the engine model, the alternator frame and the CIF price, normally inside one working day.

Do you supply parts and service after the sale?

Yes. We hold the consumable list for every rating we build and quote service kits against the engine serial number, and we provide on-site maintenance for diesel and gas sets — filter replacement, routine servicing and field repair.

What is the difference between standby and prime rating?

Standby covers emergency supply with a varying load and no overload. Prime covers continuous supply of a variable load and allows a 10 per cent overload for one hour in twelve. The same set carries both numbers, so always state which one you are quoting against.

Which industries do you supply?

Construction, mining, marine, oil and gas, data centres, hospitals, manufacturing and agriculture. The duty differs enough between them that the selection conversation starts with the application rather than with the kW.

Do you export, and on what terms?

Yes, to 50+ countries, shipping out of Shenzhen and Guangzhou. Quotations are given CIF, and the export documentation is prepared against the destination country's import requirements rather than issued generically.
