Frequently Asked Questions
What scenarios are most suitable for Weipu WS Series Connectors?
They are most suitable for industrial automation, mechanical equipment, electronic equipment, outdoor industrial facilities and automobile manufacturing fields that require stable connection, anti-vibration performance and certain environmental adaptability, especially scenarios with temperature fluctuations or humid/oily environments.
Is there any special attention during on-site installation of the Precast Cable Assembly?
During installation, please ensure that the connector is inserted in place and the locking mechanism is fastened to avoid loose connections. Avoid excessive pulling or bending of the wire harness during installation and use, and keep the harness away from high-temperature heat sources and sharp edges to prevent damage to the insulation layer.
What's the difference between plastic and metal housings of Weipu heavy-duty series?
Plastic housing: Lightweight, corrosion-resistant, cost-effective, suitable for mild low-vibration scenarios; Metal housing: High mechanical strength, strong vibration resistance, suitable for high-load high-vibration industrial equipment.
What does V-0 flame resistance mean for the WT29 series?
V-0 means the shell self-extinguishes within 10 seconds when ignited (no burning droplets), meeting strict fire safety standards for industrial environments.
