Engineered for extreme performance, hermetic reliability, and robust arc suppression across Turkey's renewable and EV ecosystems.
Istanbul, serving as the geopolitical bridge between Europe and Asia, has evolved into a premier global hub for automotive assembly, industrial machinery manufacturing, and maritime innovation. Under the Turkish National Electrification Initiative, key regions like Tuzla, Hadımköy, and Dudullu Organized Industrial Zones (OSB) are experiencing an unprecedented surge in demand for reliable power distribution components. High-voltage Direct Current (HVDC) contactors form the backbone of this transformation, acting as safe electrical switches to control high-power flows in battery systems, fast-charging networks, and heavy industries.
The transition toward electric mobility—led by Turkey's domestic EV automaker TOGG and the expanding public Trugo charging network—requires DC contactors that can handle 750VDC to 1000VDC without failure. In the maritime sector, shipyards in Tuzla are increasingly designing hybrid and fully electric tugboats for the Bosporus. These naval projects call for heavy-duty DC contactors capable of dealing with high transient currents and ensuring rapid isolation in safety-critical situations. Our high-voltage DC electromagnetic relays provide the robust arc-suppression capabilities and thermal stability that match these extreme industrial requirements.
Of Production & Export Experience
Established in 2010, Chengdu Suchen Environmental Protection Materials Co., Ltd. has grown from a specialized material developer into a multi-sector industrial powerhouse. With deep roots in metallurgy, laser/plasma cutting parts, and advanced high-voltage switching technology, we serve global heavy industries with unrivaled stability, helping enterprises in Istanbul and throughout Europe achieve their energy transition goals.
The manufacturing process of high-voltage DC contactors requires strict contamination-free cleanrooms and specialized metallurgy. Unlike standard AC switches, DC current does not cross zero naturally, creating intense electrical arcs that can destroy contacts instantly. Suchen utilizes high-purity ceramic-to-metal brazing technology, filling the contact chambers with pressurized hydrogen or nitrogen to quench arcs instantly. This ensures an electrical lifespan of tens of thousands of cycles under full load, safeguarding critical installations in Istanbul.
Istanbul’s engineering firms value not just components, but complete compatibility. Our catalog includes compact footprint relays, ideal for space-constrained electric tractor-trailers, hybrid bus powertrains, and compact DC fast-charging kiosks. By selecting Chengdu Suchen, Marmara’s systems integrators benefit from rapid prototype manufacturing, customizable busbar connections, and reliable coil terminal configurations designed to interface seamlessly with modern Battery Management Systems (BMS).

Discover how Suchen DC switching solutions are integrated into key infrastructure and industrial sectors across the Marmara region.
As Turkey transitions rapidly to electric vehicles, the demand for DC ultra-fast charging piles (150kW to 350kW+) in Istanbul is soaring. Suchen high-voltage DC relays are designed to control the main DC output loop, ensuring safe connection and disconnection during the charging sequence, and providing emergency cut-off capability under short-circuit conditions.
The maritime sector in the Port of Istanbul and Tuzla Shipyard is adopting large battery arrays to hybridize passenger ships and support vessels. Our high-voltage electromagnetic relays manage battery pack string balancing, isolations, and connection to onboard inverters, providing reliable switching in salty, humid marine environments.
Istanbul's proximity to massive industrial clusters makes local solar integration and battery energy storage essential for grid stabilization. Our customizable DC contactors act as safety interlocks in containerized battery storage projects and solar combiner boxes, protecting components from overcurrents and surges.
Istanbul's massive metro transit lines (e.g., M4, M11) require heavy-duty auxiliary electrical control cabinets. Chengdu Suchen's DC electromagnetic contactors are utilized in transit vehicle auxiliary power units (APU), heating, ventilation, and air conditioning (HVAC) systems, operating reliably through high mechanical vibrations.
Our products have passed multiple international authoritative certifications, verifying that Suchen's quality and safety meet advanced global criteria.
