FAQ

Q: Does the -40°C to +90°C temperature rating account for the mechanical vibration inside a wind turbine nacelle?

A: The temperature rating covers thermal performance only; wind turbine tower and nacelle installations should specify the optional vibration-resistant stranding upgrade.

Q: What is the difference between the 15kV medium-voltage version and a standard low-voltage LSZH cable?

A: The 15kV version uses a thicker semi-conductive insulation screen and stress-control layer at the conductor and insulation interface.

Q: What happens if a drum fails the IEC 61034-2 smoke density test after arrival at the destination port?

A: Buyers must submit a claim with test evidence within 15 days of port arrival, after which a credit note or free replacement is issued within 10 business days upon verification.

Q: What LSZH cable structures are recommended for high-flex applications?

A: For robotics, drag chains, and continuous movement equipment, flexible Class 5 stranded copper conductors with LSZH insulation are recommended to withstand repeated bending cycles.

Q: What factors should be considered when selecting an LSZH cable for a project?

A: The selection depends on voltage level, installation environment, mechanical protection requirements, and fire safety standards.
