Issues regarding plastic protective tubes for motor wiring
Thread Content
Hello everyone, I have a question. Plastic sleeves are used for the wiring from the trunking to the motor. **What are the requirements of mandatory standards for this area? Is doing this in line with the mandatory standards? I humbly request assistance from the experts.
Hello! According to the mandatory standards of **, the wiring cables of electric motors must be protected by plastic conduit that meets safety requirements. Such pipes need to possess properties such as fire resistance, high-temperature tolerance, insulation, and corrosion resistance, and they must also undergo testing and certification by relevant certification bodies. If the plastic sleeve you mentioned meets the above requirements and has passed the testing and certification by relevant certification bodies, then using it to protect the motor’s wiring complies with **mandatory standards**. If it does not meet the requirements or lacks the relevant certification, then it fails to comply with **mandatory standards**. It is best to follow **standards** when using it to ensure safety and reliability. .
In explosion-proof areas, thick-walled steel pipes must be used as wire conduits; for other areas, the requirements specified in GB 50217 shall apply.
It depends on the hazard category in your area; it’s not necessarily forbidden to use plastic protective tubes.
