Technical Specifications

Conductor and Insulation Materials

The NSSHOEU cable features tinned copper class 5 conductors manufactured according to IEC 60228 standards. These finely stranded conductors provide exceptional flexibility while maintaining excellent electrical conductivity and corrosion resistance. The tinning process creates a protective barrier that prevents oxidation and ensures long-term electrical performance in harsh environments.

The insulation system utilizes EPR compound type 3GI3 compliant with DIN VDE 0207-20 specifications. This advanced insulation material offers superior thermal stability, electrical properties, and mechanical durability. The EPR compound maintains its insulating properties across the cable's operating temperature range while providing excellent resistance to environmental stresses including moisture, chemicals, and mechanical deformation.

Sheath Construction

The cable's protective system features a dual-sheath construction designed for maximum environmental protection. The inner sheath consists of GM1b synthetic rubber compound conforming to DIN VDE 0207-21 standards. This inner protection layer fills interstices between conductors and provides additional mechanical support while maintaining cable flexibility.

The outer sheath utilizes 5GM5 heavy-duty rubber compound, also meeting DIN VDE 0207-21 requirements. This UV oil moisture resistant mobile equipment cable sheath provides the primary barrier against environmental hazards including oil exposure, moisture ingress, and ultraviolet radiation. The characteristic yellow color with inkjet marking ensures easy identification and traceability in field installations.

Electrical and Thermal Parameters

The NSSHOEU cable operates across multiple voltage ratings including 0.7/1.2 kV standard configuration with capabilities extending to 3 kV for specialized applications. The maximum permissible operating voltage reaches 0.9/1.8 kV for AC systems and 2 kV for DC applications, providing flexibility for various electrical system requirements.

Thermal performance spans from -40°C to 80°C for fixed installations and -30°C to 80°C for flexible movement applications. The maximum permissible conductor temperature reaches 90°C during normal operation, with short-circuit capabilities up to 200°C. These thermal parameters ensure reliable operation across the full range of industrial environmental conditions.

Mechanical Performance

The cable withstands maximum tensile loads up to 15 N/mm² on conductors, providing exceptional resistance to pulling forces encountered during installation and operation. Bending radius specifications allow 4× outer diameter for fixed installations and 5× outer diameter for flexible movement, ensuring proper installation without compromising cable integrity.

These mechanical specifications make the heavy-duty rubber cable for open pits and quarries particularly suitable for applications involving frequent movement, vibration, and physical stress. The cable maintains electrical and mechanical integrity even under continuous flexing and dynamic loading conditions typical of mobile equipment operations.

Environmental and Operational Resistance

Oil and Chemical Resistance

The cable demonstrates exceptional resistance to oil and various industrial chemicals according to IEC 60811-404 testing standards. This resistance ensures reliable operation in environments where petroleum products, hydraulic fluids, and industrial lubricants are present. The specialized sheath materials maintain their protective properties even after prolonged exposure to aggressive chemicals commonly found in mining and heavy industrial operations.

The oil resistance extends to both the outer sheath and inner protective layers, providing comprehensive protection against chemical ingress that could compromise electrical performance or mechanical integrity. This feature is particularly crucial for mobile equipment applications where hydraulic systems and lubricants are integral to machinery operation.
