New energy cable Installation and precautions: flexible cable is the preferred cable for power transmission materials and signal transmission carriers in the drag chain motion system, also known as drag chain cable, drag cable, mobile cable, robot cable, etc. Flexible cables are different from ordinary fixed installation cables. Please refer to the following installation and precautions during installation: the drag chain cable shall not be twisted, that is, the cable shall not be untied from one end of the cable drum or cable reel, but the cable shall be unfolded by rotating the drum or cable reel first, and the cable can be unfolded or suspended if necessary. The cable used for this occasion can only be obtained directly from the cable reel
Attention must be paid to the minimum bending radius of the cable. The cables must be laid loosely side by side in the drag chain, and arranged separately as far as possible. Use spacers to separate or penetrate into the separation cavity of the bracket gap. The gap between cables in the drag chain shall be at least 10% of the cable diameter. The cables in the drag chain shall not contact each other or be trapped together. Both points of the cable must be fixed, or at least at the moving end of the drag chain must be fixed. Generally, the distance between the moving point of the cable and the end of the drag chain should be 20-30 times of the cable diameter.
Please ensure that the cable moves completely within the bending radius, that is, it cannot be forced to move. In this way, the cables can move relative to each other or with the guide device. After a period of operation, it is better to check the position of the cable. This check must be carried out after the push-pull movement. If the drag chain is broken, its cable also needs to be replaced, because the damage caused by excessive tension cannot be avoided.
Because the halogen containing insulation layer, sheath, outer sheath and auxiliary materials of flame retardant cable are all or part of halogen containing polyethylene PVC flame retardant materials, it has high-quality flame retardant characteristics. However, a large amount of thick smoke and halogen acid gas will be generated when the cable burns. The halogen acid gas has a corrosive risk to the surrounding electrical equipment. When the cable burns, rescuers need to wear gas masks to approach the site to extinguish the fire.
power cable The burning poses a risk to the surrounding electrical equipment and rescue personnel, which leads to the failure of fire fighting and rescue, leading to serious secondary risks. The insulation layer, sheath, outer sheath and auxiliary material wrapping and filling of low smoke halogen-free cable are all or partially made of halogen-free cross-linked polyethylene XLPE flame retardant material, which not only has better flame retardant characteristics, but also has no halogen acid gas emitted when the cable burns, and the smoke emission of the cable is small, The corrosive gas caused by cable combustion is also flame retardant, and the direct compromise between reducing the amount of halogen acid gas has opened up a low halogen and low smoke flame retardant cable. Its halogen content is about 1/3 of that of halogen containing flame retardant cable. The smoke output is also close to the recognized low smoke level.
