FAQ:

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.

Does the WF Series support customization while maintaining IP67 protection?

Yes. We can provide structural adjustment, material replacement and other customization services according to customer needs. All customized products will undergo strict waterproof and dustproof testing to ensure that the IP67 protection performance is not affected. You can contact our sales team to put forward specific customization requirements.

What is the function of the 3+PE contact configuration?

The 3+PE contact configuration includes 3 contacts for transmitting power or signals and 1 PE (protective earth) contact. The PE contact is connected to the equipment shell and the earth, forming a protective earth loop. When the equipment has electrical leakage, the leakage current can be quickly discharged to the earth through the PE contact, avoiding electric shock hazards to operators and protecting the safety of equipment and personnel.
