FAQ:

How to ensure the welding quality of the Precast Cable Assembly?

We adopt automatic welding equipment and strict quality control processes in the factory. Each welding point undergoes resistance testing and pull-out force testing. The finished wire harness also undergoes overall insulation and continuity testing to ensure welding quality and connection reliability.

Is the TYPR-231-C connector compatible with other models of Weipu waterproof connectors?

The TYPR-231-C series has a standard interface size and locking mechanism. Under the premise of consistent rated parameters and pin configuration, it can be compatible with some universal industrial connectors of the same specification. For the best use effect, it is recommended to use Weipu original matching connectors.

Can the WT29 series be used with cables larger than 2.5mm²?

No. The max wire size is 2.5mm²/16AWG. Using larger cables may cause poor connection or terminal damage.

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.
