Double-sheathed cables for underground loaders, Derui electric loaders cables
Product features
Excellent material quality
Outer sheath: Made of imported polyurethane material, it features high wear resistance, oil resistance, waterproofing, corrosion resistance, and UV resistance, effectively resisting erosion from complex underground environments, such as direct ore wear, moisture, and corrosive substances.
Inner sheath: Generally selected is a specially modified elastomer nitrile or polyurethane PUR material, with a low-viscosity, strong compression design to further protect the cable's internal structure.
The structural design is reasonable
Conductor: Preferably made from multiple strands of ultra-fine oxygen-free bare copper wire, finely twisted, meeting VDE 0295 Class 5 or 6 conductor standards, ensuring excellent conductivity and flexibility, meeting the needs of frequent cable movement and bending during loader operation.
Insulation materials: Typically use high-strength TPE insulation materials or high-strength hybrid elastomer materials to ensure the cables have excellent electrical and mechanical properties, enhancing their durability.
Tensile structure: The cable-forming center is filled with steel wire ropes, aramid fibers, and other high-strength filling components. Some also use Kevlar tensile fiber braided cable tensile layers, enhancing the cable's tensile performance, allowing it to withstand significant tensile forces and prevent core wire breakage during dragging.
Torsional structure: Uses a double-sheath combined with Kevlar tensile fiber braided or aramid fiber warp-weft braided cable body, effectively stabilizing the core and providing excellent torsional deformation resistance, preventing cable spinning and avoiding twisting and deformation during frequent power supply and movement.
Performance advantages
High tensile strength: Can meet the cable tensile strength requirements during underground loader operations, generally withstanding large tensile forces. Some products can meet the 3900N tensile strength requirement, ensuring that cables do not break during pulling.
High wear resistance: The high-quality materials and special structural design of the outer sheath enable it to withstand long-term friction from ore, debris, and other materials without damage. Even in harsh underground environments with frequent movement and contact with various objects, it maintains excellent performance123.
Flame retardant performance: It has flame-retardant properties, effectively preventing fire from spreading along the cable in the event of a fire or similar situation underground, thereby improving the safety of underground operations.
Cold and oil resistance, acid and alkali resistance: Can maintain good flexibility and performance in low-temperature environments, adapting to low-temperature conditions underground; At the same time, it has good resistance to corrosive substances such as oils and acids and alkalis, and does not cause cable damage due to contact with these substances.
UV resistance and weather resistance: It can withstand ultraviolet rays and will not age or crack due to light or other factors even after long-term use underground; It also has good weather resistance, able to adapt to complex underground climate conditions.
Shallow water resistance: It has certain waterproof performance, can operate normally even in shallow water environments underground, and does not affect cable performance or service life due to water immersion.
Application scenarios
Mainly used in underground mining sites, electric loaders provide power transmission and control connections. They can also be used in mining machinery such as roadheaders and rock drilling carts. They can also be applied to related lifting, transportation, and loading/unloading machinery in waste incineration plants, waste-to-energy plants, lifting and hoisting sites, large logistics sites, iron mines, coal yards, cement plants, sand and gravel plants, port docks, and other locations, serving as connecting cables under reels/reels or similar winding and dragging shaft devices
