Key selling point: This cable is specially designed for complex and demanding industrial scenarios such as tunnel excavation and mining. Its conductors use multi-strand ultra-fine finely twisted oxygen-free copper wires, strictly complying with VDE0295 CLASS 6 standards. This conductor design not only greatly increases the conductive surface area, making current transmission smoother, but also offers conductivity far superior to ordinary cables, effectively reducing power loss and providing continuous and stable power support for wet spray trucks and other equipment. The special mixed PVC insulation layer is treated with a special process, maintaining stable insulation performance in harsh environments such as high temperature, low temperature, and humidity, making it resistant to aging and cracking, providing long-lasting and reliable insulation that fundamentally reduces leakage risks. The tin-plated copper mesh shielding layer with over 80% shielding density acts like a sturdy protective shield, efficiently resisting various external electromagnetic interferences, ensuring stable and accurate signal transmission in complex industrial electromagnetic environments, and preventing misoperation caused by signal disorder. PURJ polyurethane sheaths perform exceptionally well, with wear resistance several times greater than ordinary rubber sheaths, and are not easily worn even when frequently rubbed against hard objects such as floors or rocks; They also have excellent oil resistance, ensuring that even after long-term contact with hydraulic oil, diesel, and other industrial oils, they do not swell or deteriorate; Weather resistance is also outstanding, maintaining good physical properties whether in harsh winters or hot summers. Additionally, galvanized tensile steel wire rope and Kevlar fiber are specially added inside the cable. This combination of these two high-strength materials greatly enhances the cable's tensile performance, allowing it to easily handle tension generated during equipment movement and operation. It also has excellent torsional bending resistance, making it less likely to twist or break during reel retracting and unloading, greatly extending the cable's service life.
Specifications:
Conductor: Uses multi-stranded ultra-fine precision twisted oxygen-free copper wire, strictly complying with VDE0295 CLASS 6 standards. The diameter of a single strand is as small as 0.1mm, and the number of strands varies from tens to over a hundred depending on the cable specifications, ensuring the flexibility and conductivity of the conductor.
Insulation layer: Uses special mixed PVC material, with uniform insulation thickness between 0.5mm and 2mm, precisely matched according to cable rated voltage. Insulation resistance ≥ 100MΩ·km (at 20°C).
Shielding layer: Made of tinned copper mesh braid, with a shielding density of ≥80%, and a uniform tin plating thickness, which can effectively prevent copper mesh oxidation and improve the longevity of the shielding effect.
Sheath: PURJ polyurethane material, sheath thickness ranges from 1mm to 3mm, smooth surface, with good scratch resistance.
Operating temperature: -40℃ to 90℃. Within this temperature range, all performance indicators of the cable can remain stable, without hardening, embrittlement, or softening.
Rated voltage: Can be customized according to actual needs, commonly 300/500V, 0.6/1kV, etc., and can be customized up to 10kV to meet the power requirements of different equipment.
Cable outer diameter: varies according to specifications, ranging from 10mm to 50mm, and can be selected according to the installation space of the equipment.
Minimum bending radius: 4 times the cable outer diameter for fixed installation, and 8 times the cable outer diameter for movable installation, making it convenient for wiring installation in different scenarios.
Applicable scenarios: Widely used in waste incineration plants, providing stable power for equipment such as garbage cranes in high-temperature, dusty, and corrosive gas environments; in waste-to-energy plants, facing complex electrical equipment and oily environments, the cables' oil resistance and anti-interference performance are fully utilized; at hoisting and lifting sites, whether small cranes indoors or large outdoor lifting equipment, the cables can adapt to frequent movement and bending; during port and dock operations, humid and saline environments pose a great test for cable weather resistance, yet this cable can easily cope, suitable for ship grabs, gantry cranes, and other equipment; in underground mining operations, in dark, damp, and potentially rock-impact environments, the cable's wear resistance and tensile strength ensure the normal operation of underground mining mobile equipment.
