Quality Control
NSSHOU O/J, NSSHOU 3E, NSSHOU 3E + ST 0.6/1 kV Cable
Raw Material Test
Raw material testing is the foundation of quality assurance for NSSHOU O/J, NSSHOU 3E, and NSSHOU 3E + ST 0.6/1 kV Cables. Copper conductors are tested for electrical conductivity, tensile strength, elongation, and flexibility to ensure stable current transmission and resistance to repeated bending during mining operations. Rubber insulation and sheath compounds are evaluated through tensile strength, elongation, tear resistance, abrasion resistance, and hardness tests. These tests confirm that the materials can withstand heavy mechanical stress and continuous movement. Thermal aging tests assess long-term stability under elevated operating temperatures. Oil resistance and chemical resistance tests ensure that insulation and sheath materials maintain performance when exposed to lubricants, fuels, and mining chemicals.
Process inspection
Process inspection ensures consistent manufacturing quality of NSSHOU O/J, NSSHOU 3E, and NSSHOU 3E + ST 0.6/1 kV Cables throughout all production stages. During conductor stranding, inspections verify strand structure, compactness, conductor diameter, and flexibility. During rubber insulation extrusion and vulcanization, temperature, pressure, and curing time are continuously monitored. Insulation thickness, concentricity, and surface quality are measured in real time. Spark testing is applied to detect insulation defects and ensure electrical integrity. For NSSHOU 3E + ST cables, steel tape armoring is inspected for overlap consistency, coverage rate, and mechanical stability. Outer sheath extrusion is monitored for thickness uniformity, adhesion strength, and surface smoothness.
Finished Product
Finished product testing validates the overall quality and safety of NSSHOU O/J, NSSHOU 3E, and NSSHOU 3E + ST 0.6/1 kV Cables prior to shipment. Electrical tests include conductor resistance measurement and voltage withstand testing to confirm compliance with rated voltage requirements. Mechanical tests assess tensile strength, bending performance, impact resistance, and abrasion resistance. For armored NSSHOU 3E + ST cables, additional crushing and impact tests verify reinforcement effectiveness. Thermal aging tests confirm long-term stability, while oil and moisture resistance tests simulate real mining conditions. Dimensional inspections verify conductor size, insulation thickness, armor structure, and sheath thickness. Flame propagation tests are conducted to meet mining safety standards.
Application
NSSHOU O/J, NSSHOU 3E, and NSSHOU 3E + ST 0.6/1 kV cables are used for power supply to mining machinery in underground mines, tunnels, open-pit mines, and heavy industrial environments requiring flexible and reinforced rubber cables.
