Cummins Introduction

Cummins Inc. is a global leader in designing, manufacturing, and selling diesel and compressed natural gas engines. Cummins has invested over $140 million in China, operating Dongfeng Cummins diesel generator sets and Chongqing Cummins diesel generator sets. As a foreign investor in the Chinese engine industry, Cummins owns eight joint ventures and wholly-owned manufacturing facilities in China. Dongfeng Cummins produces B, C, and L series diesel engines, while Chongqing Cummins produces M, N, and K series diesel engines. Our products comply with standards such as ISO 3046, ISO 4001, ISO 8525, IEC 34-1, GB1105, GB/T 2820, CSH 22-2, VDE 0530, and YD/T 502-2000 Technical Requirements for Diesel Generator Sets Used in Telecommunications.

(1) Cummins Diesel Generator Set Technical Performance

Cummins diesel generator set type: Rotating field, single bearing, 4-pole, brushless, drip-proof structure, insulation grade H, conforms to GB766, BS5000, IEC34-1 standard requirements. The generator can be used in environments with sand, gravel, saltwater, and chemical corrosion.

Cummins Diesel Generator Phase Direction: A (U) B (V) C (W)

Stator: Skewed slot structure, 2/3 lap winding, effectively suppressing the waveform distortion of the neutral current and output voltage.

Rotor: Pre-balanced before assembly and directly connected to the engine via a flexible drive plate. The improved damper winding reduces oscillation during parallel connection.

Cooling: Directly driven Cummins diesel generator set centrifugal fan.

(II) Basic Characteristics of Cummins Diesel Generator Sets

Low reactance design of the generator ensures minimal waveform distortion under nonlinear loads and excellent motor starting performance.

Meets Standards: ISO8528, ISO3046, BS5514, GB/T2820-97

Common Power Rating: Refers to the continuous operating power under variable load conditions, allowing for a 10% overload for 1 hour every 12 hours.

Standby Power: Refers to the continuous operating power under varying load conditions during an emergency state.

Standard voltage is 380VAC-440VAC, all rated power at 40℃ ambient temperature

Cummins diesel generator sets feature H-grade insulation.

Service System

Implement quality assurance and warranty commitments in alignment with Cummins International standards.

Established rapid service system according to Cummins International standards: respond to customer inquiries within 30 minutes and confirm service response plan; send service personnel to the site within 4 hours; establish a 24-hour customer service hotline.

Robust National Service Network: 10 regional service centers, over 100 authorized service agents and stations, more than 600 trained service personnel, and a fully-equipped Cummins East Asia High-Power Engine User Training Center.
