Product Q&A

Q: What are the bending radius requirements for IEC60502 Three Core Cables Unarmoured Cables during installation?

A: For unarmoured multi-core cables, the bending radius shall be no less than 12 times the overall cable diameter. During installation, avoid dragging the cable on the ground. The pulling force should be applied to the conductors, not directly to the outer sheath.

Q: How is the conductor screen treated at joints?

A: At joints, the conductor screen should be stripped back according to the accessory manufacturer's instructions. The conductor screen consists of a semi-conducting tape plus an extruded layer of non-metallic semi-conducting compound. After stripping, it should be restored with a compatible semi-conducting material before applying the joint insulation, to avoid electric field concentration.

Q: How should the thermal effect between the three cores be considered when this cable operates long-term in a three-phase system?

A: After the three cores are laid up, there is a mutual heating effect between conductors. The current carrying capacity shall be determined using the correction factors for three-core assembled cables, and the ampacity data for single core cables cannot be directly applied. During installation, avoid laying multiple cables tightly in parallel. If necessary, maintain spacing or take ventilation measures as designed.
