Optimized for reliability, fast thermal dissipation, and severe sub-zero operational endurance.
Erdenet, located in Orkhon Province, stands as one of Mongolia’s most critical industrial centers, driven by the massive operations of the Erdenet Mining Corporation—one of the largest copper and molybdenum mining and processing sites in the world. As mining logistics, corporate shuttle fleets, and regional municipal transport move aggressively toward decarbonization, the demand for ultra-reliable electric vehicle (EV) charging infrastructure in Erdenet has reached an unprecedented high.
However, deploying EV infrastructure in Erdenet presents severe environmental and technical hurdles. With winter temperatures dropping to -40°C, heavy airborne copper/dust particulate matter from mining operations, and high-load continuous duty cycles from commercial heavy vehicles, standard commercial charging hardware quickly fails. Cable embrittlement, pin contact resistance spikes, and thermal contraction air gaps represent real operational hazards for operators in Orkhon Province.
As a premiere EV Charger Connector Supplier for Erdenet, Beihai Power delivers specialized, heavy-duty connector assemblies, high-amperage liquid-cooled guns, and customizable tethered cables designed specifically to overcome Northern Mongolia’s extreme environmental pressures.
A deep dive into structural material selection, contact pin metallurgy, and thermal dissipation systems required for high-reliability EV fast charging.
Our connectors utilize high-conductive copper alloy terminal pins coated with a 5-micrometer pure silver (Ag) outer plating layer. This engineering approach achieves an exceptionally low contact resistance of <0.5mΩ, preventing resistive heating even during sustained 250A to 500A power delivery cycles in Erdenet mining transport depots.
For ultra-fast 360kW and 480kW charging stations, our 400A and 500A liquid-cooled CCS1, CCS2, and GB/T guns feature internal closed-loop coolant circulation channels using environmentally friendly synthetic coolant. This maintains terminal temperature rise below 50K under maximum continuous current output.
Standard PVC cabling hardens and fractures under extreme cold. Beihai charging tethered cables employ medical-grade Thermoplastic Polyurethane (TPU) outer jackets combined with flame-retardant synthetic insulation (UL94 V-0), retaining mechanical flexibility and impact resistance (IK10) at -40°C.

Automated terminal crimping, silicone potting, and ergonomic handle housing assembly.
Simulated sub-zero load testing, temperature rise monitoring, and safety insulation checks.
Deploying specialized charging hardware for commercial logistics, heavy industrial fleets, and urban charging corridors.
Heavy mining dump trucks and industrial logistics shuttles operating around Erdenet require high-voltage DC fast charging systems (250A to 500A GB/T and CCS2 guns). Our liquid-cooled guns withstand continuous heavy usage, minimizing charging downtime during shift rotations.
Connecting Northern Mongolia's economic hubs demands weather-sealed 120kW to 180kW dual-gun floor-mounted DC stations. Equipped with auto-load-balancing connectors, these stations ensure rapid energy replenishment for interstate commercial and passenger travel.
For municipal fleets, government parking yards, and corporate offices in Erdenet, our 22kW 3-Phase AC Type 2 chargers with tethered cables provide affordable, reliable overnight charging backed by RFID access and smart OCPP 1.6J grid integration.
Addressing common technical questions regarding sub-zero operations, protocol compatibility, and bulk logistics.
Our specialized cold-weather connectors feature modified Thermoplastic Polyurethane (TPU) outer cabling jackets and silicone-rubber internal gaskets engineered specifically for sub-zero elasticity. Standard PVC cables become brittle and crack below -20°C, whereas our TPU assemblies pass cold-bend and impact tests at -40°C, ensuring safe flexibility, IP67 sealing integrity, and comfortable user ergonomics in Mongolian winters.
Air-cooled DC guns (typically rated up to 250A) rely on passive copper conductor sizing to dissipate heat, resulting in thicker, heavier cables at higher current levels. Liquid-cooled guns (rated 400A to 500A+) circulate coolant fluid along internal channels directly to the contact terminals. This allows smaller conductor cross-sections, producing lighter, highly maneuverable cables capable of delivering up to 500kW ultra-fast power delivery without overheating.
Yes. Many heavy-duty commercial haulers imported into Mongolia utilize Chinese national GB/T standards, while European and Japanese passenger EVs utilize CCS2 or Type 2. We manufacture dual-gun DC charging stations equipped with both GB/T and CCS2 connectors, operating via intelligent power distribution modules to dynamically allocate power based on the plugged vehicle standard.
All Beihai DC fast-charging guns integrate dual PT1000 or NTC precision temperature sensors directly against the positive and negative power terminals. The real-time temperature data is monitored continuously by the charger’s main controller. If terminal temperatures exceed safe operational thresholds (e.g., 85°C), the system automatically ramps down output current or halts charging to prevent connector thermal damage.
Our EV connectors offer IP55 protection in un-mated conditions (with rubber cap closed) and IP67 / IP69K ingress protection when mated to the vehicle inlet. This prevents airborne copper dust, fine quartz particles, rain, and pressure-wash water from penetrating the internal electrical contact chamber.
Standard OEM/ODM orders take approximately 2 to 3 weeks for manufacturing completion, followed by expedited rail or overland trucking transport directly from our factory to Erdenet or Ulaanbaatar via Zarubino/Erenhot customs corridors. Customization options include tethered cable length (from 3.5m to 10m+), specialized branding, custom enclosure paint, and protocol customization.
