Beiguang Jingyi recommends using a high-voltage leakage trace tester that meets the standards for use in harsh experimental environments.

In the standard "Soft PVC Plastic for Wire and Cable", it is required to conduct a trace resistance test on insulation materials, which is usually completed on a high-voltage leakage trace tester (also known as a trace resistance index tester). In harsh environments such as high temperature, high humidity, and high dust, higher requirements are placed on the stability, safety, sealing, and material corrosion resistance of equipment.

For harsh experimental environments, the following points should be emphasized when selecting equipment:

1.A stable and reliable high-voltage system: The high-voltage power supply must be very stable, have strong anti-interference ability, and be able to maintain the accuracy of output voltage and current during power grid fluctuations or environmental changes.

2.Excellent protection and sealing:

Equipment chassis: High quality stainless steel or metal materials that have undergone anti-corrosion treatment should be used to prevent moisture and corrosive gases from corroding.

Circuit boards and components should be treated with three anti paints (moisture-proof, anti salt spray, anti mold) to improve their service life in harsh environments.

Key components such as lifting mechanisms and electrodes should be made of corrosion-resistant materials (such as stainless steel and platinum electrodes).

3.Precise environmental control (if integrated): AlthoughGBT6653The experiment is usually conducted in a conventional laboratory environment, but if you refer to the "harsh environment" as the testing environment itself (such as simulating high temperature and high humidity box testing), then the equipment needs to be able to link with it or have good environmental adaptability on its own.

4.Comprehensive safety protection: It is necessary to have multiple safety measures such as high-voltage cabin door interlocking, emergency power-off, overcurrent protection, short circuit protection, and grounding alarm to ensure the absolute safety of operators.

5.Automation and data integrity: Equipment with high automation can reduce human intervention and errors, and record complete test data (voltage, current, time, leakage situation, etc.) for easy traceability and analysis.

When communicating with Beiguang Precision Instrument Business, please make sure to clarify the following configuration requirements:

1.Voltage range:GBT6653Usually requires several specific voltages (such as2.5kV）Conduct testing. Ensure that the voltage range of the equipment covers your needs (commonly known as06kV，015kVAnd there is a margin.

2.Electrode system:

Material: Platinum electrodes (compliant with standards) must be required, and plating or other materials are rejected.

Size and Pressure: Ensure Size（5mmx2mmx40mm）Angle（60°±1°) and pressure on the specimen（1.0N±0.05N）Compliant with standards and easy to adjust.

3.Drip system:

Accuracy: Drop time interval（30s±1s）And droplet size（20mm³25mmIt must be highly precise, adjustable, and stable. This is the key factor that affects the experimental results.

Material: The drip tube and needle should be corrosion-resistant (e.gPTFEMaterial) to prevent reagent crystallization blockage.

4.Current measurement and judgment:

The equipment should be able to accurately monitor the circuit current and when the current reaches the set threshold (such as0.5A）And maintain it for a certain period of time (such as2s）At this time, it can accurately determine the failure of the sample and automatically cut off the circuit.

5.After sales service and certification:

Request to provide the metrological verification certificate of the institution (such as China Institute of Metrology).

Clearly define the installation, debugging, and operation training plan for the equipment.

Understand the warranty period, as well as the prices and lead times for subsequent repairs and spare parts supply.

Pursuing high cost-effectiveness and high-quality service: Choose brands like Beijing Beiguang Jingyi, whose models are very close to imported products in terms of performance and can meet the needs ofGBT6653Testing requirements in harsh environments.
