The HZCJ-400kV20k series impulse control test system is designed to generate high-magnitude lightning impulse voltages for research and testing. It evaluates the ability of electrical equipment — including arresters, SPDs, transformers, cables, switchgears, and insulating materials — to withstand the thermal and electrodynamic effects caused by lightning impulse voltage. The system is also applicable to electrical engineering, plasma technology, fundamental physics, and environmental science research.

Q1: Is your company a sales agent or a manufacturer?
We are an integrated trade and manufacturing company with our own factory.
Q2: Can you customize our brand or the built-in software of the machine if we have special requirements?
Yes, we accept OEM, ODM, and OBM orders and can customize the built-in software of the product according to the customer's specific requirements.
Q3: What is the usual lead time? How long will it take to receive the order after placing it?
Under normal circumstances, in-stock products can be received within 5 to 7 days via the fastest international express. Other situations may vary depending on the quantity ordered, whether there are special customization requirements, and the chosen delivery method.
Q4: How do you ensure the product will not be damaged during transportation, considering its large size?
We use professional internal and external packaging to ensure the safety and stability of the products during transportation. For fragile or other special parts, we include an extra set so the customer can use the product immediately upon receipt.
Q5: How do you handle after-sales service? What if there is a quality problem or the customer does not know how to operate the product?
For quality issues not caused by human error, we provide a one-year warranty from the time of delivery, along with lifetime technical support. Other after-sales issues will be addressed by our professional technical staff within 24 hours. The product comes with a user manual and an operation video.
