    FAQ

     

    1. What does a surge protector do

    Its main function is to control the instantaneous overcurrent and voltage that suddenly enter the wire loop and signal transmission line within the range that the equipment can withstand, or introduce a strong lightning strike current into the ground to ensure that the equipment or system can be safe and stable. The work will not be damaged by impact.

    2. One line or several days of lines need to install several surge protectors.

    Usually, one is installed for the main line and one for the terminal line, and it is necessary to add one for special places.

    3. delivery time

    Under normal circumstances, the delivery time will not exceed 3 days. In special cases, such as have no enough stocks, the delivery will be delayed, and the longest delivery time will not exceed 7 days.

    4. About shipping time

    Due to the geographical location and transportation environment of different countries, the delivery time of goods in different countries is different. For example, Southeast Asian countries usually take 10-15 days, most European countries and the United States 15-25 days, etc., and remote countries may exceed 30 days. Please waiting patiently.
