HPLB300 Metal High Voltage Connector
This series of connectors is designed for high-current transmission in the electric vehicle (EV) and hybrid power markets. They support crimping for 35 to 70 mm² cables with a rated current range of 150A to 250A. These connectors are primarily used for auxiliary equipment in EV and HEV applications, including high-voltage distribution boxes, on-board chargers, battery packs, motors, and electronic controllers.
Model Description:
Remark:
1. Only plugs and sockets with identical product series, shell number, contact count, and keying position are intermateable. Example: HPLB18X-301-50-A and HPLB00X-301-D6-A.
2. This product is suitable for three cable specifications: 35 mm², 50mm² , and 70mm² . The conductor cross-sectional area shall meet the nominal cross-section requirements.
3. The cables referred to in the following text are GB/T cross-linked polyolefin cables. Tinned copper wire is recommended. If other cable specifications (e.g., silicone rubber cables) are to be used for crimping operations, please confirm and validate with our technical department.
