High pressure testing machine series (automatic pressure boost)
Category：Other
Introduction
The High Pressure Testing Machine is designed for automotive wire and cable products, providing both AC and DC high voltage insulation testing. It evaluates the dielectric strength of wires by testing insulation between cores or between the core and outer sheath, ensuring compliance with safety and quality standards.
This machine is widely used by automotive wire manufacturers, testing laboratories, and quality control departments to verify insulation performance, safety, and durability under high-voltage conditions.

FAQ
1. Can this machine test both AC and DC insulation?
Yes, the machine supports both AC and DC high voltage testing, making it versatile for a wide range of wire and cable types.
2. How is the voltage applied and controlled?
The machine features automatic voltage boost, allowing operators to preset the target voltage. The machine then gradually raises the voltage at a programmable speed (10–500 V/s).
3. What safety measures are included?
Safety features include threshold alarms, zero-voltage alarms, acousto-optic boost alarms, breakdown detection, and an emergency stop. The transformer is also protected against overloads.
4. What is the maximum test duration?
The test time is fully adjustable from 1 second to 999.9 hours, providing flexibility for short-term or long-term insulation tests.
5. Can it handle high-current breakdown tests?
Yes, the machine supports breakdown currents of up to 300 mA or 500 mA, depending on the model, making it suitable for various wire specifications.
