FAQ

LANKONG

How long is the after-sales response time?


LANKONG

We have a 24-hour after-sales service hotline, after receiving customer's after-sales request, we will make an initial response within 2-4 hours. For emergencies, we will arrange technicians to rush to the scene in the shortest possible time, the specific time depends on the geographical location of the customer, but we will do our best to ensure that we arrive at the scene within 24 hours (domestic) to solve the problem.

LANKONG

What does the after-sales service of your complete set of switchgear include?


LANKONG

Our after-sales service is very comprehensive. The first is the free repair and replacement service during the warranty period. If the equipment has quality problems during the warranty period, we will respond in time and repair or replace the faulty parts free of charge. Secondly, we provide lifelong technical support, whenever customers encounter technical problems related to equipment, you can contact our technicians, we will provide solutions. In addition, we can also provide regular equipment maintenance services according to customer needs, including equipment cleaning, inspection, fastening screws, electrical performance testing and other content, in order to extend the service life of the equipment.

LANKONG

How to debug the equipment after installation?


LANKONG

After the equipment is installed, debugging is a key step to ensure its normal operation. We will arrange professional technicians to carry out debugging, or provide customers with detailed debugging guidelines. The debugging mainly includes the measurement and setting of electrical parameters, such as the detection and calibration of voltage, current, frequency and other parameters; Testing of various protection functions, such as trigger test of overcurrent protection, short-circuit protection, grounding protection and other functions; And the communication function test of the equipment (if the equipment has a communication interface) to ensure that it can communicate with the host computer or other monitoring systems normally.

LANKONG

Is your switchgear set complicated to install? Do you need professional personnel?
