Custom high voltage test bench solutions for electrical factory laboratory.
Cooperation Case: Impulse Voltage & 6300A 3-Phase Temperature Rise Test System Project for Jiangsu Mige Electric Group

Shanghai DEMIKS Electric Technology company, a professional manufacturer of high voltage power test equipment, has successfully delivered the complete impulse voltage test system and 6300A three-phase temperature rise test system to Jiangsu Mige Electric Group Co., Ltd.
Jiangsu Mige Electric Group is a leading manufacturer of medium & high voltage power distribution equipment, specializing in pole-mounted vacuum circuit breakers, switch-gears and power automation equipment.To meet national & international type test requirements for their high-voltage electrical products, Mige Electric built a professional high-voltage test laboratory. After technical comparison, they selected Shanghai DEMIKS as their test equipment supplier.
Our delivered test system includes two core modules:
- Impulse Voltage Test System: Used for lightning impulse & switching impulse withstand voltage test, to verify the insulation performance of high voltage switch-gear, circuit breakers and power components. It can simulate lightning surge voltage and check the insulation reliability of electrical products under over-voltage conditions.
- 6300A 3-Phase Temperature Rise Test System: High-current temperature rise test bench for power equipment. It injects rated large three-phase current into switch-gear, circuit breakers and bus-bar components, detecting temperature rise of conductive parts, to validate product thermal stability under long-time rated working current.
The full test system adopts integrated control console design. Operators can realize centralized parameter setting, data acquisition, real-time monitoring and automatic report generation on the control platform. The whole set of equipment is widely used for type test, factory routine test and R&D verification of high & medium voltage electrical apparatus.
