(semi-conductive shielding resistance test equipment)
A: This equipment measures the electrical resistance of semi-conductive shielding layers in cables, ensuring they meet industry standards for safety and performance. It is critical for quality control in power cable manufacturing.
A: Look for certifications (e.g., ISO), industry experience, and customer reviews. Ensure they offer calibration services and compliance with international testing protocols like IEC or ASTM.
A: Exporters often provide globally compliant equipment, multilingual support, and streamlined logistics. They ensure adherence to destination-country standards, reducing compliance risks for buyers.
A: Calibration should occur annually or per manufacturer guidelines. Frequent use or harsh environments may require more frequent checks to maintain accuracy.
A: Verify measurement range, accuracy, software compatibility, and after-sales support. Ensure the supplier provides warranties and technical documentation for traceability.
