Core Engineering Features

Advanced Conductor Design

At the heart of the PROTOMONT (N)TSKCGECWOEU cable is its very finely stranded, tinned copper conductor (class FS). This design choice isn't arbitrary—it provides several critical advantages:

• Enhanced flexibility: The fine stranding allows for repeated bending without metal fatigue

• Improved conductivity: Optimized electrical performance under varying loads

• Corrosion resistance: Tinning provides protection against moisture and chemical exposure

• Vibration tolerance: Minimizes the risk of conductor breakage during equipment operation

The conductor design represents a careful balance between electrical performance, mechanical durability, and long-term reliability in harsh underground environments.

Superior Insulation Systems

The PROTOMONT cable employs a sophisticated multi-layer insulation system:

1. Core insulation: EPR (Ethylene Propylene Rubber) PROTOLON special compound 3GI3 provides:

• Excellent electrical insulation properties

• Superior thermal stability

• Resistance to moisture and chemicals

• Maintained flexibility across temperature ranges

2. Semi-conducting layer: The semi-conductive NBR easy-strip layer serves multiple purposes:

• Ensures uniform electrical field distribution

• Prevents partial discharge

• Facilitates easier termination and installation

• Provides an additional mechanical protection layer

3. Inner sheath: Special EPR compound GM1b creates:

• A protective barrier against mechanical damage

• Additional electrical isolation

• Improved flexibility for chain operation

• Enhanced thermal performance

4. Outer sheath: PROTOFIRM polychloroprene (PCP) special compound >5GM5 delivers:

• Exceptional abrasion resistance

• Oil and chemical resistance

• UV and ozone protection

• Superior flame-retardant properties

This multi-layered approach creates a robust cable that maintains its electrical integrity while withstanding the mechanical stresses of mining operations.

Mechanical Reinforcement System

What truly sets the PROTOMONT (N)TSKCGECWOEU cables apart is their specialized mechanical reinforcement system designed specifically for chain operation:

• Monitoring conductor: A spinning of steel/Cu-tinned wires provides:

• Structural reinforcement against tensile forces

• Monitoring capability for cable integrity

• Enhanced mechanical protection

• Improved resistance to torsional stress

• Double concentric control/PE wire spinning: Located in the outer interstices, this feature:

• Distributes mechanical stress evenly

• Provides redundant earth/ground connections

• Enhances overall cable stability

• Improves resistance to lateral compression

These reinforcement systems allow the cable to withstand the unique stresses of chain operation, where the cable must repeatedly flex while absorbing tensile forces as it trails behind moving mining equipment.
