39B1 Locomotive Cable

Detail of 39B1

The 39B1 series is a specialized locomotive cable engineered for exceptional performance and reliability in railway vehicle applications. Designed to meet the rigorous environmental and electrical demands of rolling stock, it provides a robust solution for power, control, and auxiliary circuit wiring where durability and safety are paramount.

Key Features & Benefits:

• Rugged Construction: Features a tough, resilient sheath that offers superior resistance to abrasion, oils, fuels, and chemicals commonly encountered in railway operations.

• Enhanced Thermal Performance: Rated for continuous operation at elevated temperatures (e.g., 105°C), ensuring stable performance in engine rooms and high-heat zones.

• Flame Retardant & Safety Compliant: Formulated to inhibit flame propagation and often features low smoke emission properties, contributing to enhanced passenger and vehicle safety in compliance with key railway standards.

• Flexibility & Vibration Resistance: Designed to withstand constant vibration, flexing, and mechanical stress throughout its service life, ensuring long-term connection integrity.

• Industry Standard Compliance: Manufactured to conform to specific railway application specifications, such as the DIN 5510, EN 50306, or BS 6853 series standards for rolling stock cables.

Primary Applications:

• Internal fixed wiring in electric and diesel locomotives, high-speed trains, and passenger coaches.

• Power supply and control circuits for traction and auxiliary systems.

• Wiring for lighting, HVAC, doors, and other onboard equipment in metro cars, trams, and light rail vehicles.

• General purpose wiring in other heavy-duty mobile equipment and mass transit applications.

Typical Technical Specification (39B1 Series):

• Conductor: Tinned copper, finely stranded for flexibility (e.g., Class 5 per IEC 60228).

• Insulation: Special heat-resistant, flame-retardant compound (e.g., EPR or XLPE based).

• Sheath: Heavy-duty, oil-resistant, flame-retardant compound (e.g., CSP or PVC based).

• Rated Voltage: Commonly 600/1000V or 750/1000V AC.

• Temperature Range: Typically -40°C to +105°C (flexing at -25°C).

• Standards: Compliant with specifications for 39B1 type cables as per relevant railway norms.
