Recently, Guangzhou ZEER Electromechanical Technology Co., Ltd. has strengthened its strategic partnership with German Kupplungswerk Dresden AG (KWD AG), formally obtaining exclusive distribution rights for KWD industrial couplings in China. This collaboration marks a significant expansion of the partners’ longstanding railway cooperation, establishing a more efficient and comprehensive localized service and supply system.

About KWD AG

Established in 1887 and headquartered in Dresden, Germany, KWD AG boasts over 130 years of expertise as a specialized coupling manufacturer. As a Tier-1 supplier to Deutsche Bahn, KWD possesses core technologies for rail transit drivetrains. Its products are widely deployed in high-speed trains, metros, trams, rack railways, and electric locomotives, making it Europe’s sole manufacturer providing couplings for all rail vehicle types.

ZEER-KWD Collaboration Legacy

Since its inception, Guangzhou ZEER Electromechanical has focused on electrical and mechanical interface solutions for rail systems. Building on deep industry expertise, ZEER partnered with KWD in 2015 to establish Coupling Union (Changzhou) Co., Ltd., specializing in advanced maintenance (overhauls), local assembly, and after-sales services for KWD rail couplings. With technical training and quality oversight from German headquarters, the Changzhou facility has become KWD's key service center in China.

The exclusive industrial coupling distributorship signifies KWD’s recognition of ZEER’s product expertise, market development capabilities, and technical service proficiency, demonstrating deepened bilateral cooperation.
