XLPE-HDPE Tree Cable Aluminum 25kV 1x70mm²

Raw material testing is the foundation of quality assurance for the XLPE-HDPE Tree Cable Aluminum 25kV 1×70mm². The aluminum conductor is tested for electrical conductivity, DC resistance, tensile strength, elongation, and strand uniformity to ensure stable current transmission and mechanical reliability. XLPE insulation compounds are tested for dielectric strength, volume resistivity, thermal aging resistance, tensile strength, and elongation after aging. These tests confirm the insulation’s ability to withstand medium-voltage electrical stress and long-term operating temperatures. HDPE sheath materials undergo mechanical and environmental testing, including tensile strength, elongation, abrasion resistance, environmental stress crack resistance, UV resistance, and weathering performance. These tests ensure long service life under outdoor exposure.

Process inspection ensures consistent manufacturing quality of the XLPE-HDPE Tree Cable Aluminum 25kV 1×70mm² throughout all production stages. During conductor stranding, inspections verify conductor diameter, strand construction, surface cleanliness, and concentricity. During XLPE insulation extrusion, critical parameters such as extrusion temperature, pressure, and line speed are continuously monitored. Insulation thickness, eccentricity, and surface smoothness are measured to ensure uniform electrical performance. HDPE outer sheath extrusion is inspected for thickness uniformity, adhesion to the insulation layer, and surface quality. Spark testing is conducted to detect insulation defects during production. All inspection data is recorded and reviewed. Any deviation from specifications triggers immediate corrective action, ensuring stable quality of the XLPE-HDPE tree cable.

Finished product testing verifies the safety and performance of the XLPE-HDPE Tree Cable Aluminum 25kV 1×70mm² before delivery. Electrical tests include conductor resistance measurement and AC voltage withstand testing to confirm insulation integrity. Mechanical tests evaluate tensile strength, bending performance, and impact resistance to ensure installation reliability. Thermal aging tests confirm insulation stability under continuous operating conditions. Dimensional inspections verify conductor size, insulation thickness, and overall cable diameter. Final visual inspection ensures smooth surface finish, correct marking, and defect-free construction. Only cables that pass all finished product tests are approved for shipment.
