Import Heavy Duty Alternator 8sc3009z 12v 175a/185a — Buy in Bulk from Supplier in China

The alternator model 8sc3009z delivers a nominal 12 V output with a dual current rating of 175 A continuous and 185 A peak, designed for heavy‑duty OE applications such as Caterpillar and Cummins engines. It features a high‑output design that maintains output at low engine speeds, resulting in lower acoustic emissions and a built‑in double fan capable of coping with elevated operating temperatures. Energy consumption is reported at 75 % efficiency, which is 5‑10 % higher than comparable units, and the unit is compatible with part numbers 110258, 8sc3005v, 8sc3157v and others listed in the source description.

Construction relies on a Butec/prestolite housing that provides corrosion resistance and structural rigidity; typical alternators of this class use a cast aluminium rotor and steel stator laminations to balance durability with weight. Standard industry practice for similar units includes a voltage regulation tolerance of ±2 % and a belt‑driven pulley system sized for 3‑inch pulleys. Typical noise levels for heavy‑duty alternators are below 78 dB(A) at 1500 rpm, and the double‑fan arrangement helps keep the rotor temperature under 120 °C during prolonged idle operation.

Primary buyers are OEMs and equipment importers who fit these alternators into construction and mining machinery. The supplier offers the alternator in a neutral packaging option or can accommodate custom packaging on request, but specific minimum order quantities and incoterms must be confirmed directly with the factory. Because the supplier’s response rate is currently zero, prospective buyers should verify lead‑time, payment terms and any required certifications before placing an order.

Chongqing Lange Machinery Group Co., Ltd. is located at No.65 North Jianxin Road, Jiangbei District, Chongqing 400020, China. The company is classified as an imported tier supplier with a harbour trust tier, indicating it has passed basic verification checks on the platform. Current response metrics show a response rate of 0 % and no recorded average response time, which suggests that communication may require proactive outreach.

The firm lists the heavy‑duty alternator 8sc3009z among its product catalogue and indicates the ability to supply neutral packaging or customised solutions upon request. No additional corporate history, employee count or revenue figures are provided in the source data, and the listing does not claim any specific certifications beyond the technical description.
