ECKABEL PROTOMONT (S) Reeling Cable: Robust and Reliable for Underground Mining Operations

Underground mining operations demand equipment that stands up to tough conditions, and ECKABEL PROTOMONT (S) reeling cables deliver just that.

Designed specifically for trailing and reeling applications in underground environments, these cables excel in handling dynamic loads, frequent directional changes, and high mechanical stress.

Fully compliant with DIN VDE 0250-812 standards and certified by MA (China) and the Fire Certificate of the Russian Federation, the PROTOMONT (S) is a top choice for reliability and safety.

This article delves into the cable's exceptional features, practical applications, and the benefits it brings to underground mining operations.

Applications

The ECKABEL PROTOMONT (S) cable is tailor-made for:

Underground Mining Operations: Ideal for powering scoops (LHDs), mono-spiral reels, and cylindrical reels.

Dynamic Environments: Designed to perform under conditions of frequent directional changes, extreme abrasion, and dynamic tensile stress.

Problem Solving: Addresses common issues such as sheath damage, excessive wear, and reduced cable life, ensuring longer operational durability.

Its robust design ensures operational reliability in some of the harshest mining conditions, providing peace of mind to operators and reduced downtime.

Key Design Features

The technical design of the PROTOMONT (S) cable reflects its commitment to excellence:

Conductor: Electrolytic tinned copper, class FS, for high flexibility and optimal conductivity.

Core Arrangement: Three main cores with three control/earth cores, providing a balanced and durable structure.

Insulation: Made of EPR compound type 3GI3, offering superior heat resistance and electrical safety.

Reinforcement: Reinforced with a polyester thread braid and vulcanized bonding, ensuring exceptional mechanical stability.

Inner Sheath: EPR compound type GM1B for added protection.

Outer Sheath: Synthetic elastomer compound 5GM5, colored yellow for visibility, abrasion resistance, oil resistance, and flame retardancy.

These features make the cable not just reliable but also highly adaptable to varying operational demands.
