Product Introduction

The SXCY Series High-Voltage Impulse Generator is a high-energy testing system developed for evaluating the insulation strength of electrical equipment under severe transient voltage conditions. It generates controlled impulse voltage and impulse current for simulating lightning and switching transients, providing a reliable test source for transformers, GIS, cables, bushings, insulators, surge arresters and other high-voltage equipment.

Core Advantages

High-Energy Test Capability
The SXCY Series is designed for high-energy impulse testing, with available configurations reaching up to 320 kJ of impulse energy. This enables testing of large-capacity electrical equipment and demanding insulation systems.
Wide Output Voltage Range
Different generator configurations cover output levels from ±100 kV to ±4800 kV, supporting applications ranging from conventional high-voltage testing to ultra-high-voltage laboratories.
Stage-by-Stage Expansion
The generator uses a multi-stage structure. By adjusting the number of stages, the system can be configured for different voltage and energy requirements.
Adaptable Electrical Parameters
Impulse capacitance, stage capacitance, energy capacity and damping resistance can be selected according to the intended test application.
Suitable for Large Electrical Equipment
The system is designed to provide the high-energy impulse source required for testing large and high-voltage electrical apparatus.
Project-Specific Configuration
Rather than relying on a fixed configuration, the system can be engineered according to the customer's test object, voltage level, energy requirement and laboratory conditions.
