FAQ | Single Phase Line Fitting Heat Cycle Test System
1. What is a Single Phase Line Fitting Heat Cycle Test System?
This is a professional testing device for verifying the thermal cycling durability of single-phase power line fittings, clamps and connectors. It simulates actual grid load and temperature cycle changes to detect aging, poor contact, overheating and performance degradation of fittings, providing accurate data for product R&D, quality inspection and certification.
2. What industry standards does this test system comply with?
The system complies with mainstream industry standards including IEC 60840 and IEC 62067. It supports standardized thermal cycle tests for overhead line fittings and power connectors, ensuring test results are valid and acceptable for third-party certification and factory quality audits.
3. What are the core technical parameters of the system?
Core technical parameters: Rated capacity 45kVA, output voltage 0–15V, continuous test current 30A–3000A, measurement accuracy up to 0.5%FS±3 words. It supports long-term continuous operation, precise multi-channel temperature monitoring and customizable test cycles for diverse test scenarios.
4. What test objects is the system applicable to?
It is applicable to thermal cycle and temperature rise tests of all single-phase power line fittings, such as wire clamps, cable connectors, compression fittings, insulating and grounding fittings. Widely used in factory inspection, third-party testing, grid sampling inspection and product performance verification.
5. What are the main test functions of the equipment?
It integrates full-featured automatic test functions: constant current automatic loading, adjustable temperature cycle parameters, real-time temperature data recording, automatic cycle counting, intelligent safety protection, automatic stop and test report generation. It enables unattended full-process tests to verify the long-term operational stability of line fittings.
6. Is the test process fully automatic? Does manual supervision required?
The system supports fully automatic intelligent testing. After setting cycle times, current, temperature threshold and holding time via software, the equipment can automatically complete loading, cycling, data recording, alarming and shutdown. No real-time manual supervision is required, effectively improving test efficiency and avoiding human errors.
7. Does the system support customized test cycle and parameters?
Yes, it supports flexible parameter customization. Users can independently set cycle times, temperature rise/fall rate, high-temperature holding time, current loading duration and interval time, adapting to personalized test schemes for different fitting specifications and meeting R&D and certification test requirements.
8. What safety protection functions does the equipment have?
The equipment is equipped with comprehensive safety protections: over-current, over-temperature, short-circuit, overload and abnormal power-off protection, as well as real-time fault alarm.
