Product Q&A

Q:What is the warranty period and coverage?

The warranty period is 1 year (3 years for core components), covering manufacturing defects and installation issues, excluding human or natural disaster damage.

Q:How to handle overheating or discharge faults?

Cut off power to cool down, check joint torque and installation; if loose or damaged, after-sales will reprocess and test insulation to prevent fault expansion.

Q:What to do if SF6 gas chamber leaks?

Stop operation immediately and contact after-sales; technicians will detect leakage, provide free repair or replacement within warranty, and verify pressure interlock.

Q:How to troubleshoot DTU communication failures?

Check SIM card, tariff, and antenna; verify server address and baud rate; contact after-sales for remote assistance or on-site maintenance if issues persist.

Q:How are out-of-warranty maintenance services charged?

Charged based on spare parts cost plus on-site service fee with transparent standards; annual maintenance packages are available with preferential prices.
