ABB 12556917-738385 RADOX GKW cable

Product Overview

12556917-738385 RADOX GKW is a special cross-linked cable developed by ABB for the electrical transmission needs in harsh industrial environments. It adopts a composite structure design of "multi strand conductor cross-linked insulation shielding layer oil resistant sheath", and its core function is to achieve stable transmission of power supply between industrial equipment and precise transmission of control signals. This cable eliminates the shortcomings of traditional PVC cables, such as poor temperature resistance, easy aging, and weak oil resistance. Through RADOX ® Electron beam cross-linking technology modifies the insulation layer to form a three-dimensional network cross-linking structure, greatly improving the high temperature resistance, aging resistance, and mechanical strength performance of the cable. Its conductor is made of multiple strands of soft copper wire twisted together, which has good flexibility and conductivity, and can adapt to equipment vibration and complex wiring requirements; The outer sheath is made of special oil resistant rubber material, combined with a shielding layer design, which can resist the erosion of oil and chemical reagents, and effectively suppress electromagnetic interference, ensuring the quality of signal transmission. At the same time, the cable complies with international standards such as IEC 60228 and VDE 0250, and is compatible with the wiring requirements of ABB series contactors, frequency converters, sensors, and other automation equipment, providing reliable support for the integrated wiring of industrial electrical systems.

Core functional features

1. RADOX ® Cross linked insulation technology ensures excellent electrical performance

The cable insulation layer adopts ABB's patented RADOX ® Electron beam cross-linked polyethylene material, after electron beam irradiation treatment, the insulating material molecules form a stable three-dimensional cross-linked structure. Compared with traditional PVC insulation, its insulation resistance is increased by more than three times (insulation resistance under normal conditions ≥ 10 ¹Ω· km), and the dielectric strength reaches 20kV/mm, which can effectively prevent short circuit faults caused by insulation breakdown. At the same time, the cross-linked structure greatly improves the high-temperature resistance of the insulation layer, with a long-term working temperature of up to 125 ℃ and a short-term temperature tolerance of up to 150 ℃ (duration ≤ 5s), which can adapt to the wiring needs of high-temperature environments such as metallurgical workshops and boiler surroundings. In addition, the cross-linked insulation layer has excellent aging resistance, with a service life of over 15 years under rated conditions, far exceeding the 5-8 years of traditional cables, significantly reducing cable replacement frequency and maintenance costs.

2. Oil and chemical resistance, suitable for harsh industrial environments

The outer sheath of the cable is made of special hydrogenated nitrile rubber (HNBR) material, which has been modified with a special formula and has super strong oil resistance. It can withstand long-term immersion in various industrial oil stains such as mineral oil, lubricating oil, hydraulic oil, etc. After 72 hours of oil immersion, the volume change rate of the sheath is ≤ 5%, without cracking, swelling or other phenomena. It is particularly suitable for oil intensive areas such as automobile manufacturing workshops and mechanical processing plants. At the same time, the sheath material has good chemical corrosion resistance, which can resist the erosion of chemical reagents such as acid, alkali, salt spray, etc. It can still maintain stable mechanical and insulation properties in the acidic and alkaline environment of the chemical workshop. In addition, the surface of the sheath has undergone anti slip treatment, which combines wear resistance and scratch resistance, reducing sheath damage caused by dragging and friction, and extending the service life of the cable.

3. Shielding structure design to suppress electromagnetic interference

In response to the complex electromagnetic environment of industrial sites, the cable adopts a dual shielding structure of "copper wire weaving+aluminum-plastic composite tape", with a shielding coverage rate of ≥ 95%, which can effectively suppress the interference of external electromagnetic radiation on the internal signals of the cable, and prevent the signals transmitted by the cable itself from generating electromagnetic radiation on surrounding equipment. For specifications used for signal transmission control, the dual shielding structure can control the attenuation of electromagnetic interference to above 40dB, ensuring the transmission accuracy of weak signals such as 4-20mA analog signals and pulse signals, and avoiding equipment control failure caused by interference. The shielding layer is woven with tin plated copper wire, which not only improves conductivity and oxidation resistance, but also facilitates grounding treatment, further enhancing anti-interference effect.

4. Excellent mechanical performance, adaptable to vibration and complex wiring

The cable conductor adopts a multi strand thin copper wire twisted design (with a single wire diameter of 0.2mm, and the number of strands can reach 30-100 according to specifications). Compared with a single strand hard conductor, its flexibility is greatly improved, and the minimum bending radius is only 6 times the outer diameter of the cable (static bending), which can easily adapt to the complex wiring space and frequent vibration environment inside the equipment. At the same time, the anti fatigue performance of the stranded conductor is excellent. Under vibration conditions of 10-500Hz and amplitude 1mm, it can withstand more than 1 million vibration impacts without conductor fracture. The overall mechanical strength of the cable is high, with a tensile strength of ≥ 12MPa and a fracture elongation of ≥ 150%. It can resist external forces such as drag and tension during wiring and use, avoiding transmission failures caused by conductor damage.

5. Wide temperature range adaptability to cope with extreme temperature environments

Relying on RADOX ® The synergistic effect of cross-linked insulation and temperature resistant sheath enables the cable to have a wide range of temperature adaptability, with a long-term working temperature range of -40 ℃ -125 ℃. It can work stably in outdoor equipment and internal wiring in high-temperature workshops in northern cold regions. In a low temperature environment of -40 ℃, the cable can still maintain good flexibility without sheath cracking or insulation embrittlement when bent; In a high temperature environment of 125 ℃, the insulation layer will not soften or flow, and the electrical performance remains stable, fully meeting the needs of extreme temperature conditions in industrial sites.

6. Environmental and safety features, in compliance with international standards

The cable is made of environmentally friendly materials that are halogen-free, low smoke, and flame-retardant. The insulation layer and sheath are free of heavy metals such as lead, cadmium, mercury, and halogen elements, which comply with the requirements of the EU RoHS 2.0 environmental directive. During combustion, the cable has a low smoke density (smoke density level ≤ 50) and does not release toxic or harmful gases, which can effectively reduce the risk of personnel injury and equipment damage in the event of a fire. At the same time, the cable has flame retardant properties and complies with the IEC 60332-1-2 flame retardant standard. It can self extinguish during vertical combustion testing, avoiding the spread of flames and improving the fire safety level of industrial electrical systems.
