Latest company blog about YJV32 / YJV42 Steel Wire Armored Cables for Mine Shaft, Deep Well and Vertical Heavy-Duty Power Supply

YJV32 and YJV42 are steel-wire armored cross-linked polyethylene (XLPE) power cables designed for extreme vertical installations, power supply for mine hoists, deep-well wiring in factories, and heavy-duty machinery load projects.

Unlike traditional steel-tape armored cables, YJV32/YJV42 utilizes a galvanized steel wire armor structure, providing exceptionally high tensile strength to withstand the immense vertical tensions in mines and deep wells. They also effectively resist mechanical impacts, crushing, rodent bites, and harsh underground corrosive environments. For electrical engineers, building contractors, mining project developers, and power distributors, YJV32 and YJV42 are the preferred standard solution for vertical heavy-duty power distribution in demanding industrial and mining environments.

Core Structure and Professional Performance Advantages
  • Structure: Copper conductor + XLPE insulation + inner sheath + steel wire armor + outer sheath
  • Ultra-high tensile strength: Can withstand long-distance vertical suspension tension, perfectly suited for vertical laying in mines and deep wells
  • Strong mechanical protection: Resistant to compression, impact, and rock cutting
  • Rodent and termite prevention: The steel wire armor effectively blocks the gnawing and damage from rodents in underground and mountainous environments
  • XLPE insulation: Can operate continuously at 90℃, low dielectric loss, aging resistant, and stable electrical performance
  • Good corrosion resistance and moisture resistance: Suitable for damp mine soils, humid deep well environments, and corrosive industrial environments
Model Differences
  • YJV32: Single-layer steel wire armor, suitable for vertical laying with medium tensile strength and conventional underground engineering.
  • YJV42: Double-layer steel wire armor, with stronger tensile strength and mechanical protection, suitable for ultra-deep mines, ultra-long vertical drops, and power supply for heavy equipment.
Main Application Scenarios
  • Vertical power supply for mine shafts, power distribution for mine hoists and underground mining equipment
  • Deep well and pump shaft wiring in factories, and long-distance vertical shaft wiring in basements
  • Power transmission through vertical shafts in heavy industrial equipment and power distribution in terrains with significant elevation differences
  • Mountain engineering, deep-buried tunnel shafts, and engineering projects in harsh geological environments
  • Places requiring high tensile strength, rodent protection, and strong mechanical damage protection
  • Heavy-duty vertical shaft power supply in large industrial parks and power distribution for remote underground engineering projects
Professional Laying and Installation Methods
  • Vertical Shaft/Deep Shaft Suspension Laying

    Core application of YJV32/YJV42; relies on steel wire armor to bear its own weight and vertical tension, ensuring safety and reliability, suitable for long-distance, high-drop vertical suspension.

  • Underground Cable Trench and Pipe Gallery Laying

    Suitable for high mechanical pressure, rock compression, and complex geological conditions.

  • Direct Burial Laying in Harsh Terrain

    Suitable for mountainous areas, rocky soils, areas infested with rodents, and engineering areas susceptible to compression.

  • Heavy-Duty Fixed Laying for Machinery and Equipment

    Suitable for heavy industrial machinery and fixed vertical power supply lines subjected to frequent vibration and external impact.

Installation and Laying Precautions
  • Strictly Control Tension

    During vertical hoisting and laying, never exceed the cable's rated tensile force; avoid excessive pulling to prevent damage to the conductor, insulation layer, and armor structure.

  • Protect the Outer Sheath and Armor Layer

    During transportation and construction, avoid dragging, scratching by sharp stones, and severe impacts; once the outer sheath is damaged, moisture will seep in, shortening its service life.

  • Bending Radius Meets Standards

    The bending radius should meet the minimum bending radius standard for steel wire armored cables; excessive sharp bends will cause deformation of the steel wire armor layer and damage to the internal insulation layer.

  • Vertical Laying Fixed Support Standards

    When laying cables vertically in shafts, fixed support points should be set at regular intervals to distribute the cable's weight and reduce long-term concentrated tensile stress.

  • Armor Grounding

    Both ends of the wire armor must be reliably grounded to prevent induced voltage and ensure the safe operation of medium- to high-power systems.

  • Environmental Restrictions

    Avoid construction in extremely low temperatures, heavy rain, and muddy mine environments; ensure the construction environment is dry and clean.

  • Corrosion Protection and Sealing Treatment

    For damp deep wells and mining areas, proper sealing and corrosion protection treatment should be applied to cable joints to prevent water infiltration and oxidation-induced heat generation.

Value and Engineering Selection Reasons in Power Engineering
  • Solves the problem of ordinary cables being unable to withstand the vertical tensile forces in mines and deep wells.
  • Integrates three major protective properties: tensile strength, resistance to mechanical damage, and rodent protection.
  • Reduces line failure rate and frequency of maintenance, lowering long-term operating costs.
  • Provides stable power transmission performance, suitable for heavy-load, continuous industrial power supply.
  • Complies with international IEC standards, suitable for bidding on global mining, industrial, and infrastructure projects.

YJV32 and YJV42 steel wire armored cables are indispensable professional choices for applications such as mine shaft power supply, factory deep well wiring, and high-drop power distribution for heavy equipment. They possess superior tensile strength, excellent mechanical protection, and rodent and corrosion resistance, perfectly adapting to various harsh underground and vertical laying environments. Engineers and construction personnel can select YJV32 or YJV42 based on actual vertical drop and tensile strength requirements, and strictly adhere to standardized installation specifications to ensure the long-term safe, stable, and low-failure-rate operation of heavy-duty power distribution systems.
