Heavy-Duty Mining Cable | MSHA & UL 1277 Certified for Underground Operations

Short Description:
Heavy-Duty Mining Cable
Engineered for extreme underground and surface mining operations, our MSHA & UL 1277-certified mining cable delivers unmatched safety and durability. Featuring triple-layer shielding, oil/abrasion-resistant EPR insulation, and -40°C to 90°C temperature tolerance, it powers haul trucks, drills, and conveyors while resisting crushing, chemicals, and explosions. Ideal for hazardous Zone 1/2 environments.

Product Overview
Engineered for extreme mining environments, our mining cable delivers unmatched durability, safety, and performance in underground and surface operations. With triple-layer shielding-40°C to 90°C temperature resistance, and MSHA/UL certifications, it powers haul trucks, drills, and conveyors while resisting abrasion, chemicals, and impact.

Key Features & Benefits

1. Ultra-Durable Construction

  • Conductor: Oxygen-free tinned copper (Class 5 flexibility)

  • Insulation: EPR (Ethylene Propylene Rubber) for heat/oil resistance

  • Jacket: CSP (Chlorosulfonated Polyethylene) – resists UV, chemicals, and tearing

  • Shielding: Braided copper + aluminum foil + grounding drain wire (triple EMI protection)

2. Safety-Certified Design

  • MSHA 30 CFR Part 18 Certified: Explosion-proof for hazardous underground zones

  • UL 1277 Listed: Meals flame-retardant requirements

  • IEC 60502-2 Compliant: Global mining safety standard

3. Technical Specifications

Parameter Specification
Voltage Rating 600V–2000V
Temperature -40°C to +90°C
Bending Radius 6× cable diameter
Conductor Sizes 6 AWG to 500 MCM

Applications

Ideal for:

  • ✅ Shuttle Cars & Haul Trucks

  • ✅ Draglines & Drilling Rigs

  • ✅ Conveyor Systems & Hoists

  • ✅ Explosive Environments (Zone 1/2)

Why Choose Our Mining Cable?

Problem Solved

Standard cables fail quickly in mining due to:

  • ❌ Abrasion from rocks/equipment

  • ❌ Oil/grease degradation

  • ❌ Voltage spikes causing fires

Our Solution

  • Extended Flex Life: 1M+ bend cycles (tested per ICEA S-75-381)

  • Oil Resistance: Passes UL 1277 Oil Immersion Test (168 hrs @ 100°C)

  • Flame Retardancy: Self-extinguishing per UL 1581 VW-1

Installation Guide

  1. Bending: Minimum radius = 6× cable diameter

  2. Termination: Use MSHA-approved connectors (e.g., Eaton Cutler-Hammer)

  3. Maintenance: Inspect every 500 hrs for jacket abrasion

⚠️ Warning: Non-MSHA cables risk explosions in gassy mines!
