Product Q&A

Q:What is the warranty period of the ring main unit, and what does the warranty cover?

The warranty period is 1 year (3 years for core components), covering manufacturing defects, component quality failures and installation process issues; excluding damages caused by human factors or natural disasters.

Q:How to deal with overheating or discharge faults at cable joints?

First cut off power to cool down, check the joint tightening torque and installation process; if there is looseness or damage, after-sales will reprocess the joint and conduct insulation testing to prevent fault expansion.

Q:How to handle SF6 gas chamber leakage of the ring main unit?

Stop equipment operation immediately and contact the after-sales team; technicians will use professional instruments to detect leakage points, provide free repair or replacement of the gas chamber within the warranty period, and verify the pressure interlock function.

Q:What is the troubleshooting method for DTU communication failures (such as inability to connect to the network or abnormal data transmission)?

First check the SIM card installation, tariff status and antenna connection; then verify configuration parameters such as server address and baud rate; contact after-sales for remote assistance or on-site maintenance if the problem persists.

Q:How to charge for maintenance services outside the warranty period?

Charged based on the cost of spare parts required for maintenance + on-site service fee with transparent standards; annual maintenance packages are available with preferential prices and priority services.
